It would be interesting to see a current A-Z update on your electrical set as it is now. Maybe with links to the batteries and other items needed for the full setup. Thanks for all you do!
I know this is already 3+ years old, but this was super helpful into getting a basic understanding of what to expect when considering an ambo build. I appreciate the details! Thanks!
Lefty is so hilarious, I wonder what he thinks when you just start talking to the camera, the way he looks at you is truly funny. I've watched you from the beginning and you totally amaze me with the beautiful home you put together. It would be very easy to be very happy living in it. Your knowledge is amazing and so is your channel.
I've seen 2-3 videos of yours now that deal with electric, wiring, solar, etc and you are always good and clear about being careful along with warnings and good detailed info, there is a lot of value in your videos I am saying again. Thanks man.
Appreciate all your teachings and tips. Enjoyable introduction music on every video...very soothing. Naturally love Lefty since I work in an animal rescue shelter and have two rescues.
If you are doing a conversion this is the Channel you must watch! This channel not only gives you pertitnant info it gives it to you in a safe and very clear way making it easy or easier for even a novice to understand!
This means a lot. I am currently doing my research and so far a retired ambulance will be the best for what I am looking for. I will be doing a cross Canada research documentary for my PhD and I am now seeing I will need to connect with a proper electrician for my use of an ambulance. I am very utilitarian in my needs so the luxury videos are cute but not necessary. Your knowledge is necessary. so thank you. V.
Hi Niki and thank you for watching. I'm happy that the videos help you gather info and make decisions. An ambulance is a great start to a great travel vehicle that give you a lot of options. Have fun with it!
Your vidoes abotu chosing and ambluance and then working with the systems in the vans are the best I have found anywhere! Thank you so much for sharing your experiences and your knowledge!
Wonderful basic presentation. I just bought a 2002 ambulance without an inverter so i am trying to figure out how to set up house lights, air cond, heater, computer, refridg. This video was a great start to get me going. Xlnt presentation.
Thank you Mike - I'm glad you're grabbing some information from the videos! Remember, the wiring is all basic stuff really; dig into it and trace your wires... it will all start to make sense after that :)
This was so informative especially for the non-electrician. All I've heard is that an ambulance is a wiring nightmare. You're so generous with your knowledge! This was excellent. You are a natural-born teacher. Tell Lefty "who's a good dog? Are you a good dog?" for me :) please.
This is a very very good video! You do an excellent job of simply explaining in layman terms all of the electrical functions pre-existing in your rig and also how you built them out. Great job!
I am looking for an ambulance to turn it into a camp. Your valuable videos clear a lot of my questions. Thank you so much, man! Looking forward more of your videos.
I'm only 9 minutes into this, and I can already say this is a superb video. Thank you for doing this. Without you and people like you, many of us would have to learn everything the hard way. I've picked up about lead-acid batteries to never let them get below about 55 percent charge. The reason for that is because it destroys the batteries and you'll need to buy a new one much quicker. That's not the case with lithium batteries. You can discharge them all the way with no issues. When I heard that the van lead-acid batteries went dead a few times (below 55 %, I'm guessing), you had to recharge them with your portable generator. It made me think of this. Lead-acid batteries are perfect for starting vehicles. The alternator almost immediately recharges the battery to 100 percent soon after the engine starts, provided you drive your vehicle regularly. They are not so good at running the "House" due to the reasons listed above. Cheers
Been watching campulance videos for a couple of years because they are already insulated, wired and built to withstand accidents. I have come to realize that the wiring would be way beyond my skill set. Your explanation of the difference between the van and the house was illuminating but I will hire professionals to make sure I avoid any snafus. I subscribed in a heartbeat when I saw Lefty. It is a bonus to hear you explain the ins and outs of owning a campulance because you do so in such an easy going manner(made me smile when you dropped the F bomb). Please continue your informational vlogs interspersed with Lefty shenanigans'...
Thank you Cherel. Soak up everything you can when you have the work done and know too that there are a lot of people on the road that will help out if you have any issues while traveling :) Yes, I do cuss sometimes!!! But not at Lefty :)
Thank you for going in depth and explaining your experience with the system. Mine is very similar. It's a 96 Chevy. The main power switch in the front actually is used for the van electrical & the starter batteries. I think I will leave all of that intact for now, and build my home system completely separate. You made it seem less intimidating thanks again
Thank you, thank you, thank you! My skills are vast and varied but I've always shied away from electrical/mechanical as I never felt I had enough time to fully absorb it properly, as I deal with an OCD brain. All in or all out baby! This will be such useful info as I explore converting my "new" '85 E350. My goal is this ambo as a starter conversion to use for personal local business and a stepping stone to a live-in vehicle. You have helped me so much! Thanks Dave
Hey! So I recently purchased a type 2 ambulance and begun learning how these things operate. It was helpful that the maker, AEV, was really responsive to my request for information about the electrical system and quickly e-mailed a full graphic. Your presentation here is absolutely wonderful! I am just halfway through it at the moment and I am impressed with your teaching ability. I am really confident that I will be able to add solar to my rig and to understand the big picture as well as the details. That way when problems arise, I will have a head start on isolating the issue. I had thought I'd have to hire an electrician to bring me up to speed. Just want to say a big thank you to you for sharing your knowledge with us!
Thank you so much! I am in the process of buying an ambulance. My son tried to explain all of this to me, but I have been very thick in absorbing what he is telling me. I totally get what you are saying! Once I figure out what I want/need, I will be able to have my son (marine engineer) and my brother (marine electrician) help me. But I totally need to understand what is what and how it works!
I was lucky enough to buy two identical ambulances at auction. One eas decommissioned wear a lot of relays were removed and more sloppily cut grounds and things. I didn't know which one to start with to get running or keep. I was selling one keeping the other. I decided to keep the one with the cleaner motor with the remanufactured 6.0 diesel tags on the valve covers . That was last week so far it runs like a top I had to figure it all out my own I don't know anything about diesels luckily mine still had most everything intact except for a lot of relays and weird buttons and under the column rubber plunger thing that I found was what keeps it from going to drive as a theft to turn when they're running. Ty for this sir.
Thank you! this is such a great video to get a start how to figure out the ambulance electrical system because it is overwhelming when you see just the amount of wires and systems!!
Wow! Thank you! :) I'm hoping to buy a used Ambulance late winter and although I don't plan to hook up the electrical myself, I want to have a good understanding of it. In many of the ambulance conversions I watched, they talk about not using the existing electrical & it has seemed so wasteful. So, very happy to hear your knowledge of the typical systems used in them. Blessings to you and yours...
wow, we just bought a 2013 ambulance with a 2006 remount and are seriously overwhelmed. I'm having an ambulance mechanic go over all the wiring as it has been butchered when they took all the siren, flashing lights etc out. Cost ly but will give me a place ot start. The battery under the stair well was an eye opener. I thought like you that it was for the interior
Don't get overwhelmed- if items were removed and you don't need them, the wires can be capped off and left. I honestly don't use any of the factory items, but left outside scene lights and interior dome lights operational. The best thing is to become familiar with everything - it's really not complicated but seems so in the beginning :)
Good information about the electrical system and how you had to do all your DC wiring. I learn more by watching how it’s done but at least I did take in some things that I might have to go back to help or get help from someone else who knows what they are doing and I will watch them so I could figure out how to fix it if needed.Thank you very much.
I commented that I had access to a ambulance and you send message. Just checked. After almost a year being up for sale . It would be that it was sold!. It is very interesting that you are going over electrical since the ambulance had a problem with the back house. I would have never known how that electrical would be needed or how to fix!
Excellent explanation! I am taking notes. I was a first responder for 28 years and I have used the ambulance with the switch and without the switch. I've spent a lot of time in the Frazer Ambulance which uses a generator and one circuit board to power the box. I could also plug into shore power at the station to keep my box cool in the Texas heat. Your video here has been the best explanation of how to separate these systems and add the solar power. I do not have an ambulance or campulance of my own yet. I am just doing the research for now. I have an idea of how I want to setup the inside and keep the cabinetry which I've been so used to for many many years. I am also looking at composting toilets. I have a pull behind RV camper that I stayed in for four years but it is cumbersome to setup for towing. With the campulance I can take my motorcycle and go. I am also researching insurance BEFORE I buy.
Great information! I am looking to buy an ambulance to use as an office and to pull a travel trailer behind to actually live in. I plan on adding solar to both the ambulance and my travel trailer so I can work and live anywhere. You helped me understand the ambulance part much better. Thank you!
@@TheCampulanceMan I have spent the last two hours watching your videos. Great information. I do like touring other setups but your the only one who has explained installs etc. I would like to buy a sticker but can't figure out how to do it.
What ties the two systems *together is not at the cutoff (which you videoed then at your seat), but rather at the “Main” switch, usu labeled as such on the console. NOTE: There are always a couple of circuits that remain HOT all the time, like a clock; trace em out. (Every wire is labeled). Also, run a conduit from one side to the other and front to back for future use; I used an old garden hose, and can add wires easily without going into the insulation(!). Definitely cap any cut wires, cuz the decommissioning process by the last owner is often rather crude. I wasn’t able to get a diagram from my builder, WheeledCoach. I have a Generac generator as well (ONLY for emergency). Make sure you keep its bowl clean or it’ll definitely fail. It’s considered a low-quality generator by repair shops.
Each manufacturer has differences and my rig had no constant hot to the box when the main seat switch was off. My seat switch stopped all power to the house and now acts as a gateway between my crank and house batteries.
Thanks for taking the time to do this! You covered a lot of great information, and I've thought the same thing about wiring closets I've seen on others' ambo builds....when we do our build I'll disconnect most things, and eventually pull all the stuff that's not connected/needed to clean up the space. Great video. :D
My semi has 4 batteries for starting the truck. It then has 4 batteries for the bunk. The alternator charges all the batteries. I have the big inverter and shore power option. I have a TV, microwave oven, 2 outlets for ac. I usually run the truck when using the microwave.
Good informative video, I'm getting ready to look into all those wires. Mine is probably different from yours being a 94 model F-350. You did clear-up some things thought between the cab and the house. Thanks...!
Thank you Fred - my hopes are that the videos help people with their work! The F series ambulances are very similarly configured to the E series except there's usually 2 batteries under the hood... I'll lend a hand if you need info :)
On the rigs I'm looking at has the Battery Bank is in the a Drawer built-in to the rear Bumper. If I end up getting it I'll probably use my Jackery Power Unit (and a 100w Harbor Freight Solar Panel kit) as "Stage Zero" of the house power.
I'll be adding the victron system from my bus, to my ambulance. I'll be adding a DC, to DC converter. I've been in my shuttle bus, for 18 months. So, ive got an idea of what's going on. I've also got an on/off switch, and, a breaker box from an offshore fishing vessel, that has a 120 breaker wired to each switch. Also, I'm running a 2"x ¹/4 bus bar setup, with 10 connections, positive, side, 10 connections, negative side. I run two charge controllers, to control each side of my panels, without either side hurting the other, no matter how I'm parked.
Does the switch on the driver’s seat activate relays that then allow the 12v to power the inverter and the 12v items? In which case does the 12v come from the batteries to the relay?
On my truck, the seat switch connected the crank batteries to the inverter and the power cabinet. Then a small rocker switch turned on the rear switch panel. That was its original config.
@@TheCampulanceMan Interesting. That's a lot of current through that switch. I know some use the switch to activate a relay or solenoid witch actually carries the current. Your setup seems simpler. As long as the switch holds up.
This is the most helpful video i have ever seen on youtube. I just picked up an ambulance, and didn't even know what the seat switch did. My outlets in the house are not getting any power. I have a feeling the electric side of this is going to kill me.
Thank you for watching and your comment I do appreciate it! The electronics can be conquered - start looking at and tracing wiring and make diagrams of all of it. Let me know if I can help :)
Great explanation. I'm trying to get my wiring right in a ford stripped chassis e150 5.4L based SHERROD rec van. Have a lot of exposed wiring that I don't know where they lead to. The TV, rear DVD, game console etc was on a sub panel behind drvr seat, plus power fold 3 row seat, rear ac/heat. I want to series relay power @ 120v but am not experienced with that type of wiring. Any types on ga sizing. ( using 14vdc relays in series to directly make a 3 prong DC electric circut. ) RESEARCH says that this is the same as a house 120v AC circuit and has the same wiring size requirements, BUT can cause potential hazards (fire & shock, if not properly grounde, looped to prevent standby power waste etc.) I have (2) 200A 14.4V relays direct from b+ of 230A alternator. 1 at b+, 1 at + of 2nd start battery parallel to engine bay battery. Where should I install the series 50a relays? I was thinking of a 2nd salvage engine bay fuse box wire. The one that connects alternator to starter and fuse box with the L shaped metal connector that powers the entire fuse box. Wouldn't that provide the "right" power type & amount to the whole series string of relays to make a 120vdc 50A POWER STRIP? THANKS FOR ADVISE ON THIS? REALLY APPRECIATE THE HELP.
My 120v system: from the shore power plug, it runs in to a breaker box through a 20a breaker (just like house style). That then feeds into my inverter/charger. My inverter AC output goes to the same breaker box and through 15a breakers. Then that output runs to the wall outlets. It's a simple system really and is how the ambulance was originally wired. I did upgrade the wiring to a larger gauge - 14ga as recommended by the inverter manufacturer. You need to convert your DC power to AC power using an inverter.
Thank you so much for these videos. I am in the process of attempting to go over all of your vids from start to present because your information is greatly needed and appreciated. We are in the process of buying our first ever rig and to be honest I have no idea how to go about this. I have found a rig that I am interested in buying and I will be getting in contact with you vis email (if I may please) to run some things by you. Again, I love your videos and love all the knowledge I'm gaining from you. Please, you and Lefty be safe out there, God bless you both.
If there is a native AC unit, why the addition of the window unit? Is it more efficient? How long can you run the AC on your batteries? We are in the market and are planing. We will keep it shore power only and add in the solar system later.
Hi - the rear AC in my, and most all other ambulances, works only when the engine is running. It's good to use when we're traveling to keep the back cool but can't be used when we're camped. Good question...
I just bought an ambulance. 2003 E450. I don't have the manual switch on the driver seat. What I have is a commander 300 vstart which after 5 minutes cut the power in the house. There are almost 0 info on that module. Still searching...nice video TY
Nice job with your breakdown of the systems, I'm trying to get back on track with a project I've wanted to do for years, which is to install my ambulance inverter charger in my Tahoe, which over time became a solar powered set up , in my head, I believe it's a vanner ™ & I believe is in many ways identical to your Ames,,, ie; inverter/charger switchable & roughly the same power specs... I now have solar panels which should yield 100watts of energy to the charge controller, & would like to use them to power the inv./Chrgr. But when I went to connect the dots & see which piece to try to work out squiring & juz got caught up in Soo many variations and the technological gains and a new & wide range of capabilities & ways of using it,,,till my little intended couple of u tube sessions/research turned into more and more that I've gotta decide about, and I know my measley 100 watt setup is nothing compared to most and use of out there today from what I'm seeing and all these videos. It's what I managed to become able to afford and when it went on sale, I found a way to get it, I guess I'm just wondering , so that I'm not trying to save up for more than I need & making the expense any more than necessary since having to go on disability & huge loss of income, I have to be very extremely creative & patient especially to do any extra projects like I always have, but I'm blessed, & patience is a virtue!! Sorry I've gone on so long , so , long story short, if you or anyone ur subs has any info or recommendations on products, parts, Or 12v , 24v , 48v pros n cons,, batteries,,,, that might help me to piece together a quality smaller system with what I have so far... Would be greatly appreciated,,, and save me a good bit of my hairline...lol thanks 4 listening,,,🤔 or reading,,& any links or advice !!
Sorry if I missed this in the comments somewhere. If you wanted to charge your house batteries off your van alternator, couldn't you just flip the master switch while the engine was idling (or while driving) rather than hooking up the generator?
any idea where the house electrical disconnect switch is on the 2006 ford E450 / medtec is? there is a module disconnect toggle on the center console but I don't think this does the same thing
Many rigs (and mine) have the main disconnect switch, then a second toggle switch. The main and the toggle switch both have to be on to get power to the box. When you flip you toggle, does the box lose all 12v power? It may be triggering a disconnect relay...
Another helpful video, thank you! Just a FYI, my ambulance is a 1996 Chevrolet 3500 7.4 with a Horton box. The 'On / Off ' switch on mine, next to the drivers seat, powers On everything and powers Off everything, both in the truck and the box. So when it is 'Off' it can not be started. However there is a 'module' Connect / Disconnect switch on the cab control panel that powers the box 'On / Off ' What did you do with the two battery cables that were wraped in gauze, are they now connected to the inverter? I was not clear about that part.
Yes those cables were for the inverter. I replaced them with new larger cables and connected them to the new inverter. I've seen another rig with that type off switch - thanks for sharing that!
@@TheCampulanceMan Of the (4) four cables running into the inverter compartment on my ambulance, two are the 'shore power' in / out, and the other two, which are cut, one of those has 12v DC and the other is just bolted to the frame under the truck, is that the normal setup for an inverter connection? They appear to be 2/0 (00) or 3/0 (000) cables based on a OD measurment of 0.6625".
@@Nonthanburi2 Yes, from what you described those are the 12v cables that would connect to the inverter. The frame mount is negative and the other is positive. I would recommend running both of those directly to your house batteries. No frame ground. The shorter those cables are, the better. You may have noticed I put my batteries right next to my inverter for that reason. The longer the cable, the larger they must be to minimize voltage drop. Good work tracing your wiring!
I have 1998 E450 Ambulance (McCoy Miller). I have the two battery tray in the box. I have a 700ma draw with the rig off. In the battery tray compartment there is a single stud where the battery positive is connect to two large gauge wires. I find that most of the drain is going to the sub panel in the box. I tried disconnecting that one from the system to see if the rig would start and the cab is dead. This rig needs both fat wires to be connected to the battery to start. My truck has a battery switch on the side of the drivers seat. This seems to control a relay. With everything hooked up the cab is dead without the battery disconnect being on. Switch it on and everything works. The 700ma draw is there regardless of the switch position. My Box has a fairly large PC board in a cabinet. There is always power to this board and I think this is where the 700ma is going. For some reason the box needs to be powered in order to start the engine. I was hoping to separate the two parts and am just getting into figuring out how. McCoy Miller doesn't respond to inquiries. I have to believe at some point there was build documentation for this truck. Some one didn't just free form wire it. I know its 22 years old so its likely long gone. My end goal would be to have a separate system for the running the truck. I would love to just remove all the ambulance electronics and start fresh in the box. The thing is all the lights in/out of the box are relay controlled by that big board in the box. And for some reason the starting circuit for the truck seems to be tied to the Box electronics. Any information source would be helpful. I could probably find a E450 schematic from 1998. That might help to figure out where the Box electronics are interfering with the starting circuit. We are in Northern Vermont and just started to mess with this project.
You made the statement that the "house" is separate from the "vehicle (van)". how are the lights for normal traffic in the "house" wired. Like turn signal, tali lights, clearance lights, backup lights etc.
Hi Charles - the taillights/turn signals/reverse are a part of the chassis wiring (van powered). The clearance lights are powered by the house batteries but relay triggered by the van wiring. The scene lights are house battery powered.
I just bought an ambulance and trying to tackle this. I have the switch in the seat like you said and my inverter is missing and I have no house batteries as of yet but in your video you you said that the switch will switch from van to house. Now I was told that I needed to turn the switch to both ( batteries) to start the truck. Is this not the case?
It depends on how yours is wired. The way I wired mine, the switch is between the 2 battery banks and connects them together. Most rigs, the switch is just to turn on the box, but I've seen different wiring methods.
do you still have main switch hooked up for emergency starting power in case starting batteries go dead just wondering ? may see you out there some day after get past some barriers going on in my life right now
@@TheCampulanceMan That's what I figured. I have worked on diesel ambulances but mostly Gms. When I was at a Chevy dealership. Best thing for a diesel is change filters often. Maintenance is way more important on diesel. The fuel is dirty and filters are big for a reason!
I bought two type 2 ford 350 vans. Neither van has a switch. One has 4 batteries (but identical vans in almost every way ) one has 3. The one with 3 has a 110 breaker box behind the seat. The one with 4 doesnt. The only switch that I have that I know of to control the systems is the overhead main power switch. It's confusing despite leader Incorporated did send me the schematics and I have novice level knowledge on 12 volt systems, i havent made sense of it. Any input appreciated
The best tip I have is to start tracing battery cables to find out how it's wired. They typically all join, then feed the 12v distribution cabinet and feed the inverter. Once you've figured that out, you disconnect them from the cabinet and inverter, add your new 2nd battery bank, and connect your new batteries to the cabinet and inverter.
@@TheCampulanceMan I have 3 now and am buying 4 more. I will be converting to construction vehicles and you inspired me to try one like yours. I can check if any have higher headspace... I am in Middletown NY, Orange County.
@@TheCampulanceMan Cool, I will defiantly work with you since your videos have been great and I have only seen a few. I will check them all first before using them for the construction trade. My construction guys don't make me any money if they are hanging in the vehicle...
Hi Sorry if this was already asked somewhere, but what would you say is the total output in a day that your system would be capable of? I don't know much about electronics, I am looking at building an ambulance like yours out, and wondering if I'd be able to run a desktop computer and game at all.
I have been lucky enough to find a company that does electrical and lighting for emergency vehicles in my town, amazing. The tech there suggested I keep my inverter, I think to use for shore power. We are going to sit down and go over everything but was curious about what you thought? Would you have kept yours if you had one? If so, why? I think my components for my solar system should all be new? (inverter, charge controller, batteries etc.) Thanks!
Many of the rig inverters are 1000watt, and I needed to have 2000watt minimum so I installed a 3000watt unit. Mine is an inverter charger so shore power still works with it. It depends on how much power you'll be using (air fryer, hot plate, microwave, etc) that will determine how big of an inverter you'll need.
Gotcha, I am planning on having 1200w of solar on top and I think I need a 3000w inverter/charger as well. I also plan on getting 4 - 200 watt hour deep cycle lithium phosphate batteries and of course a charge controller...all for the house solar system. I will also keep the shore power capabilities. I am of the same mind as you when it comes to not wanting to have to watch every watt I use! Having said that, would there be any use otherwise for the ambo's inverter?
@@anniewisecarver744 Only if you wanted to have 2 inverters. I would replace the original inverter with your new inverter/charger, then sell the old inverter on Ebay. They can bring decent money as they're typically UL certified units.
Can you add solar panels and a charge controller and tie into the original system and use the stock ambulance inverter to power the house? I understand you run the risk of draining the batteries and not being able to start the van, just curious if it's do able
Yes, you can add solar to the ambulance batteries. You already mentioned the drawback, but it can be done. My friend Pam's rig is set up that way and she's been using it for a few years now, but she did have additional batteries added to the crank system so she has 1 very large battery bank that cranks the engine and powers her box/devices.
@TheCampulanceMan right on! Thank you for taking the time to reply. I am looking at picking up an older k3500 ambulance sometime this week. Your videos have already been so incredibly helpfull
Hi David! I just purchased an Ambulance as well and in the process of converting it. My question is that you said a few time to keep the house and truck batteries completely separate, but what about being able to charge your three house batteries VIA the alternator while driving? I'm also changing over the shore power plug in to charge the three house batteries as well, So my though is I can charge my batteries three way, while driving , with shore power and with solar... Let me know what you think about this! Id love to hear.
Hi Erika - yes you can connect the 2 systems through a battery bank charger, that gives you the ability to charge from alternators if desired. That will still keep the 2 systems seprate from each other :)
My 94 e350 has two master switches. right side of seat controls the house. Left side of the seat shuts the whole vehicle down. I stripped the house of everything. Re-insulated the house. Took out lights, air conditioner and heat. All cabinets, bench, seat, cabinets and counter top. Cut and removed much wiring and have a lot to go. I have two battery's under the hood. No inverter. I have installed shore power but don't have house battery yet. Solar down the road sometime. I know how I want to finish but cost is more than I planned so slow going. I have been following you as I see you are from Rochester, ny. I am a retired police lieutenant from Watertown, ny. I am in Kansas but legal resident of South Dakota for tax purposes. I will have some more questions as I go. You are the one source I have found, re ambulance build, that has been helpful. My girlfriend plan to be full time at some point. Later.
Hi James and thank you for watching. Sounds like you went real deep on the customizing!! If there's anything I can help with let me know and have fun on your build!!
Hi David. After watching this I went out to check my ambulances switches. The one on my seat kills all power to the van and house. There is a switch on my counsel that says master, that kills the house only. Mine is a 97 ford e350. Yours looks alot like mine. I'm just shorter i think.
Thanks for inspiring me to buy an ambulance! I am converting it into an office/moving van for my nonprofit. I bought a 2000 Ford E-350 turbo diesel type III ambulance yesterday. I don't think I am going to have to make many changes to it, it just needs some minor body work, painting and cleaning. I will probably add solar panels later this year. I am having a hard time finding replacement keys for the outside storage lockers. Any ideas? I also need a replacement round rear brake light. I hope you plan to visit Hawaii soon, if you do, let me know. You can stay in my Campulance! Aloha!
An ambulance makes a great platform for businesses - great choice! The locks, if like mine, are standard type and can be replaced as a cylinder or the whole handle with lock, for low cost: amzn.to/3fcSNug
thank you for the informative videos. Just wondering when you mentioned the original wiring for the fan and a/c in the box is there a productive way of using the existing air ducts from the original install with your new heater or new a/c units? Thanks (maybe a good topic for a video)
It would be interesting to see a current A-Z update on your electrical set as it is now. Maybe with links to the batteries and other items needed for the full setup. Thanks for all you do!
BEST explanation on electrical systems needed for van life I have seen so far!!! Thank you, Campulance Man 😃
Thank you :)
This really clears up the few points of concern/confusion I had about the wiring. Very helpful.
Glad it helped
I know this is already 3+ years old, but this was super helpful into getting a basic understanding of what to expect when considering an ambo build. I appreciate the details! Thanks!
Thanks - I'm glad it helped!
Lefty is so hilarious, I wonder what he thinks when you just start talking to the camera, the way he looks at you is truly funny. I've watched you from the beginning and you totally amaze me with the beautiful home you put together. It would be very easy to be very happy living in it. Your knowledge is amazing and so is your channel.
Thank you Ellen - I've tried to make us comfortable in the truck and we're getting there :)
Just bought a 2001 E350super duty Marque for commercial use but now thinking about CAMPER. Your videos are great . Thank you for sharing.

Thanks John - that's a perfect rig for it!
Great information, I dont own an ambulance, but am factory certified repair tech for 2 ambulance manufacturers and worked on them for 10 years.
Hi David - thank you! Means a lot coming from a tech!
Can we get your email sir lol
I'm getting ready to buy an ambulance. Tomorrow in fact.
I really like Lefty, he is like so many Pit's. My female Pit is the same age as Lefty with the same personality.
You know how it is then - they are actions dogs!!
Thank you for making this so much more understandable! Now I just have to find an electrician who can do all of this. I will show them this video.
Glad it was helpful!
I've seen 2-3 videos of yours now that deal with electric, wiring, solar, etc and you are always good and clear about being careful along with warnings and good detailed info, there is a lot of value in your videos I am saying again. Thanks man.
I learned from my mistakes over the years... a lot of 'whoops'!! Thank you for the encouragement.
I was going to say the same thing. These videos are awesome
Appreciate all your teachings and tips. Enjoyable introduction music on every video...very soothing. Naturally love Lefty since I work in an animal rescue shelter and have two rescues.
Many thanks! I was lucky to catch Lefty's eye at the shelter all those years ago :)
If you are doing a conversion this is the Channel you must watch! This channel not only gives you pertitnant info it gives it to you in a safe and very clear way making it easy or easier for even a novice to understand!
Thanks Rob!
This means a lot. I am currently doing my research and so far a retired ambulance will be the best for what I am looking for. I will be doing a cross Canada research documentary for my PhD and I am now seeing I will need to connect with a proper electrician for my use of an ambulance. I am very utilitarian in my needs so the luxury videos are cute but not necessary. Your knowledge is necessary. so thank you. V.
Hi Niki and thank you for watching. I'm happy that the videos help you gather info and make decisions. An ambulance is a great start to a great travel vehicle that give you a lot of options. Have fun with it!
Your vidoes abotu chosing and ambluance and then working with the systems in the vans are the best I have found anywhere! Thank you so much for sharing your experiences and your knowledge!
Thank you Liz!!
Thanks! A ton of good information.
Who the hell would give this a thumbs down? Maybe someone that spent $30k on a van build out.
Thank you Tim. I appreciate that :)
Thank you so much. I am so grateful for your experience. Lmao at your response to lefty. I can totally relate. That love hate relationship. So cute.
Wonderful basic presentation. I just bought a 2002 ambulance without an inverter so i am trying to figure out how to set up house lights, air cond, heater, computer, refridg. This video was a great start to get me going. Xlnt presentation.
Thank you Mike - I'm glad you're grabbing some information from the videos! Remember, the wiring is all basic stuff really; dig into it and trace your wires... it will all start to make sense after that :)
This was so informative especially for the non-electrician. All I've heard is that an ambulance is a wiring nightmare. You're so generous with your knowledge! This was excellent. You are a natural-born teacher. Tell Lefty "who's a good dog? Are you a good dog?" for me :) please.
Thank you! Their wiring is actually not to complicated once you dig in :)
You sound like very kind man.🥰
That's a very nice comment, thank you.
This is a very very good video! You do an excellent job of simply explaining in layman terms all of the electrical functions pre-existing in your rig and also how you built them out. Great job!
Thank you for your comment! I appreciate that :)
I am looking for an ambulance to turn it into a camp. Your valuable videos clear a lot of my questions. Thank you so much, man! Looking forward more of your videos.
Thank you MD!!
Did ya find one?
I'm only 9 minutes into this, and I can already say this is a superb video. Thank you for doing this. Without you and people like you, many of us would have to learn everything the hard way. I've picked up about lead-acid batteries to never let them get below about 55 percent charge. The reason for that is because it destroys the batteries and you'll need to buy a new one much quicker. That's not the case with lithium batteries. You can discharge them all the way with no issues. When I heard that the van lead-acid batteries went dead a few times (below 55 %, I'm guessing), you had to recharge them with your portable generator. It made me think of this. Lead-acid batteries are perfect for starting vehicles. The alternator almost immediately recharges the battery to 100 percent soon after the engine starts, provided you drive your vehicle regularly. They are not so good at running the "House" due to the reasons listed above. Cheers
Lefty needs his own channel
thank you sooooo much for all of this useful info!! i also appreciate the amazon links to each item in your system!
Been watching campulance videos for a couple of years because they are already insulated, wired and built to withstand accidents. I have come to realize that the wiring would be way beyond my skill set. Your explanation of the difference between the van and the house was illuminating but I will hire professionals to make sure I avoid any snafus. I subscribed in a heartbeat when I saw Lefty. It is a bonus to hear you explain the ins and outs of owning a campulance because you do so in such an easy going manner(made me smile when you dropped the F bomb). Please continue your informational vlogs interspersed with Lefty shenanigans'...
Thank you Cherel. Soak up everything you can when you have the work done and know too that there are a lot of people on the road that will help out if you have any issues while traveling :)
Yes, I do cuss sometimes!!! But not at Lefty :)
Thank you for going in depth and explaining your experience with the system. Mine is very similar. It's a 96 Chevy. The main power switch in the front actually is used for the van electrical & the starter batteries. I think I will leave all of that intact for now, and build my home system completely separate. You made it seem less intimidating thanks again
I'm glad the videos are helping out! Thank you for watching and commenting :)
Who made your module (house)? Mine’s a 96 type-I WheeledCoach.
Awesome video - Great information. I'm going to learn some electronics & I'll watch this video probably a bunch more times if I need to.
Thanks Mike!
Thank you, thank you, thank you! My skills are vast and varied but I've always shied away from electrical/mechanical as I never felt I had enough time to fully absorb it properly, as I deal with an OCD brain. All in or all out baby! This will be such useful info as I explore converting my "new" '85 E350. My goal is this ambo as a starter conversion to use for personal local business and a stepping stone to a live-in vehicle. You have helped me so much! Thanks Dave
Thank you Wendy :)
Hey! So I recently purchased a type 2 ambulance and begun learning how these things operate. It was helpful that the maker, AEV, was really responsive to my request for information about the electrical system and quickly e-mailed a full graphic. Your presentation here is absolutely wonderful! I am just halfway through it at the moment and I am impressed with your teaching ability. I am really confident that I will be able to add solar to my rig and to understand the big picture as well as the details. That way when problems arise, I will have a head start on isolating the issue. I had thought I'd have to hire an electrician to bring me up to speed. Just want to say a big thank you to you for sharing your knowledge with us!
Thank you! It sounds like you're getting your arms around the electrical systems! If you run into questions let me know :)
Lic Elec .... owned alarm co. (Low voltage)... if ya have issues ?quest. Dm me. Will help if can
Hi I also have a type 2. Leader manufactured. Can I get your email I would love to ask a couple ?s please. Ty in advance
Thank you so much! I am in the process of buying an ambulance. My son tried to explain all of this to me, but I have been very thick in absorbing what he is telling me. I totally get what you are saying! Once I figure out what I want/need, I will be able to have my son (marine engineer) and my brother (marine electrician) help me. But I totally need to understand what is what and how it works!
Thank you! So glad I helped :) That's why I'm here!!!
I was lucky enough to buy two identical ambulances at auction. One eas decommissioned wear a lot of relays were removed and more sloppily cut grounds and things. I didn't know which one to start with to get running or keep. I was selling one keeping the other. I decided to keep the one with the cleaner motor with the remanufactured 6.0 diesel tags on the valve covers . That was last week so far it runs like a top I had to figure it all out my own I don't know anything about diesels luckily mine still had most everything intact except for a lot of relays and weird buttons and under the column rubber plunger thing that I found was what keeps it from going to drive as a theft to turn when they're running. Ty for this sir.
Thank you! this is such a great video to get a start how to figure out the ambulance electrical system because it is overwhelming when you see just the amount of wires and systems!!
Wow! Thank you! :) I'm hoping to buy a used Ambulance late winter and although I don't plan to hook up the electrical myself, I want to have a good understanding of it. In many of the ambulance conversions I watched, they talk about not using the existing electrical & it has seemed so wasteful. So, very happy to hear your knowledge of the typical systems used in them. Blessings to you and yours...
Great to hear of another joining the fleet!! Have fun with your planning and building :) Thank you for watching and commenting!
That's because of the lazy people don't want you to use them they want to be paid to use their own new systems
wow, we just bought a 2013 ambulance with a 2006 remount and are seriously overwhelmed. I'm having an ambulance mechanic go over all the wiring as it has been butchered when they took all the siren, flashing lights etc out. Cost ly but will give me a place ot start. The battery under the stair well was an eye opener. I thought like you that it was for the interior
Don't get overwhelmed- if items were removed and you don't need them, the wires can be capped off and left. I honestly don't use any of the factory items, but left outside scene lights and interior dome lights operational. The best thing is to become familiar with everything - it's really not complicated but seems so in the beginning :)
Good information about the electrical system and how you had to do all your DC wiring. I learn more by watching how it’s done but at least I did take in some things that I might have to go back to help or get help from someone else who knows what they are doing and I will watch them so I could figure out how to fix it if needed.Thank you very much.
Thank you :)
Very good video David I am sure you are helping a lot of folks!!!! Your build is soooo clean and tidy, this is absolute one of my favorite channels!!!
Thank you Wattsa! I was upset at myself for not dusting off my gear before shooting the video :(
@@TheCampulanceMan It is very clean considering the roads you go down LOL
I commented that I had
access to a ambulance and you send message. Just checked. After almost a year being up for sale . It would be that it
was sold!. It is very interesting that you are going over electrical since the ambulance had a problem with the back house. I would have never known how that electrical would be needed or how to fix!
Thank you Sandra!! :) If you need help let me know...
Thanks for making these videos, you’ve given me confidence to tackle mine.
Awesome!!! Glad to give you the push :)
I just started an ambulance, wiring ambulances for the first time never. I look forward to all... I have an unquestionable thirst
Get after it Jackie!! You'll become expert :)
Do not listen to him
I have some experience with them
@@thomasharrington6454 Thomas, the ambu conversion community needs your help! Try ambulancerv.com FB, IG, and Reddit !
Excellent explanation! I am taking notes.
I was a first responder for 28 years and I have used the ambulance with the switch and without the switch. I've spent a lot of time in the Frazer Ambulance which uses a generator and one circuit board to power the box. I could also plug into shore power at the station to keep my box cool in the Texas heat.
Your video here has been the best explanation of how to separate these systems and add the solar power. I do not have an ambulance or campulance of my own yet. I am just doing the research for now. I have an idea of how I want to setup the inside and keep the cabinetry which I've been so used to for many many years. I am also looking at composting toilets. I have a pull behind RV camper that I stayed in for four years but it is cumbersome to setup for towing. With the campulance I can take my motorcycle and go. I am also researching insurance BEFORE I buy.
Excellent comment Kelly thank you! Sounds like you're an ambulance expert!!!
Yes :)
More videos like this.
I really learned something I didn't know.
Lefty is so darn cute, too!
(edited for typos)
Thank you!
Best Vid so far my friend! THANK YOU!!!👍
Very nice informative video. And Lefty puts in his 2 cents as well. Thanks.
Thank you! Lefty always goes for an appearance!!!
Awesome content. I have had 2 ambulances and the electrical is overwhelming sometimes. I have learned a lot. Thank you so much!
Thank you!
Cast your bread upon the water and it will come back twice. 💕
Extremely helpful and informative, thank you.
Great information! I am looking to buy an ambulance to use as an office and to pull a travel trailer behind to actually live in. I plan on adding solar to both the ambulance and my travel trailer so I can work and live anywhere. You helped me understand the ambulance part much better. Thank you!
Great! I'm glad that it helped you out. Thank you for watching!
Great job thanks for the info! Hope to build mine soon.
THANKS YOU alot of help..more help.....t
So incredibly helpful. Thank you so much.
Good information especially on the Solar. Would like to see how your house type A/C is vented to the outside.
My AC unit is in a rear outside cabinet - I open that cabinet door ro expose it to the outside. Thank you for watching and commenting!
@@TheCampulanceMan Thanks for responding. I just found your a/c video. Thanks again.
@@TheCampulanceMan I have spent the last two hours watching your videos. Great information. I do like touring other setups but your the only one who has explained installs etc. I would like to buy a sticker but can't figure out how to do it.
@@highway75 In the video description of all my newer videos there's a PayPal link for getting a sticker. Thank you!!
What ties the two systems *together is not at the cutoff (which you videoed then at your seat), but rather at the “Main” switch, usu labeled as such on the console. NOTE: There are always a couple of circuits that remain HOT all the time, like a clock; trace em out. (Every wire is labeled). Also, run a conduit from one side to the other and front to back for future use; I used an old garden hose, and can add wires easily without going into the insulation(!).
Definitely cap any cut wires, cuz the decommissioning process by the last owner is often rather crude. I wasn’t able to get a diagram from my builder, WheeledCoach.
I have a Generac generator as well (ONLY for emergency). Make sure you keep its bowl clean or it’ll definitely fail. It’s considered a low-quality generator by repair shops.
Each manufacturer has differences and my rig had no constant hot to the box when the main seat switch was off. My seat switch stopped all power to the house and now acts as a gateway between my crank and house batteries.
Gotta love Lefty....blah blah blah. Get to the point...dogs...got a love em
Thanks for taking the time to do this! You covered a lot of great information, and I've thought the same thing about wiring closets I've seen on others' ambo builds....when we do our build I'll disconnect most things, and eventually pull all the stuff that's not connected/needed to clean up the space. Great video. :D
Thank you Pat - It's all really just simple wiring - just a lot of it!
Great explanation on the setup and how to break it down into smaller chunks.
Thank you!!
Excellent overview. Thanks so much for the information.
Thanks Woody!
My semi has 4 batteries for starting the truck. It then has 4 batteries for the bunk. The alternator charges all the batteries. I have the big inverter and shore power option. I have a TV, microwave oven, 2 outlets for ac. I usually run the truck when using the microwave.
Good informative video, I'm getting ready to look into all those wires. Mine is probably different from yours being a 94 model F-350. You did clear-up some things thought between the cab and the house. Thanks...!
Thank you Fred - my hopes are that the videos help people with their work! The F series ambulances are very similarly configured to the E series except there's usually 2 batteries under the hood... I'll lend a hand if you need info :)
On the rigs I'm looking at has the Battery Bank is in the a Drawer built-in to the rear Bumper.
If I end up getting it I'll probably use my Jackery Power Unit (and a 100w Harbor Freight Solar Panel kit) as "Stage Zero" of the house power.
You have a lot of options and can go a lot of different directions :)
@@TheCampulanceMan
I learned that the Inverter in this rig is crapped out, and at it's age is probably Square Wave.
@@TheCampulanceMan
A detail I like about the "Van" ambulance control panel is that it's built in to the Roof, instead of the Doghouse.
I'll be adding the victron system from my bus, to my ambulance.
I'll be adding a DC, to DC converter.
I've been in my shuttle bus, for 18 months.
So, ive got an idea of what's going on.
I've also got an on/off switch, and, a breaker box from an offshore fishing vessel, that has a 120 breaker wired to each switch.
Also, I'm running a 2"x ¹/4 bus bar setup, with 10 connections, positive, side, 10 connections, negative side.
I run two charge controllers, to control each side of my panels, without either side hurting the other, no matter how I'm parked.
That's a great system you're putting in! What a fun project :)
Does the switch on the driver’s seat activate relays that then allow the 12v to power the inverter and the 12v items? In which case does the 12v come from the batteries to the relay?
On my truck, the seat switch connected the crank batteries to the inverter and the power cabinet. Then a small rocker switch turned on the rear switch panel. That was its original config.
@@TheCampulanceMan Interesting. That's a lot of current through that switch. I know some use the switch to activate a relay or solenoid witch actually carries the current. Your setup seems simpler. As long as the switch holds up.
Good breakdown.
This is the most helpful video i have ever seen on youtube. I just picked up an ambulance, and didn't even know what the seat switch did.
My outlets in the house are not getting any power. I have a feeling the electric side of this is going to kill me.
Thank you for watching and your comment I do appreciate it! The electronics can be conquered - start looking at and tracing wiring and make diagrams of all of it. Let me know if I can help :)
YOU ARE AWESOME !!!! THANKS SO MUCH !!!!!!
Just bought an ambulance. Ill have to get a closer look at my wirong
The best thing you can do is go over all the wiring and trace it out so you're familiar with it!
@@TheCampulanceMan A cursory Google search indicates that the company that made mine still exists so I’m going to try to contact them about a diagram.
Great explanation. I'm trying to get my wiring right in a ford stripped chassis e150 5.4L based SHERROD rec van. Have a lot of exposed wiring that I don't know where they lead to. The TV, rear DVD, game console etc was on a sub panel behind drvr seat, plus power fold 3 row seat, rear ac/heat.
I want to series relay power @ 120v but am not experienced with that type of wiring. Any types on ga sizing. ( using 14vdc relays in series to directly make a 3 prong DC electric circut. ) RESEARCH says that this is the same as a house 120v AC circuit and has the same wiring size requirements, BUT can cause potential hazards (fire & shock, if not properly grounde, looped to prevent standby power waste etc.)
I have (2) 200A 14.4V relays direct from b+ of 230A alternator.
1 at b+, 1 at + of 2nd start battery parallel to engine bay battery.
Where should I install the series 50a relays? I was thinking of a 2nd salvage engine bay fuse box wire. The one that connects alternator to starter and fuse box with the L shaped metal connector that powers the entire fuse box.
Wouldn't that provide the "right" power type & amount to the whole series string of relays to make a 120vdc 50A POWER STRIP?
THANKS FOR ADVISE ON THIS? REALLY APPRECIATE THE HELP.
My 120v system: from the shore power plug, it runs in to a breaker box through a 20a breaker (just like house style). That then feeds into my inverter/charger.
My inverter AC output goes to the same breaker box and through 15a breakers. Then that output runs to the wall outlets. It's a simple system really and is how the ambulance was originally wired. I did upgrade the wiring to a larger gauge - 14ga as recommended by the inverter manufacturer.
You need to convert your DC power to AC power using an inverter.
Do yo have video from start to finish of redoing interior .
LOVE YOUR DOG!!!
Thank you so much for these videos. I am in the process of attempting to go over all of your vids from start to present because your information is greatly needed and appreciated. We are in the process of buying our first ever rig and to be honest I have no idea how to go about this. I have found a rig that I am interested in buying and I will be getting in contact with you vis email (if I may please) to run some things by you. Again, I love your videos and love all the knowledge I'm gaining from you. Please, you and Lefty be safe out there, God bless you both.
Thank you Scott for watching and commenting. You can email anytime - my address is in the descriptions of all my newer videos
If there is a native AC unit, why the addition of the window unit? Is it more efficient? How long can you run the AC on your batteries? We are in the market and are planing. We will keep it shore power only and add in the solar system later.
Hi - the rear AC in my, and most all other ambulances, works only when the engine is running. It's good to use when we're traveling to keep the back cool but can't be used when we're camped. Good question...
I just bought an ambulance. 2003 E450. I don't have the manual switch on the driver seat. What I have is a commander 300 vstart which after 5 minutes cut the power in the house. There are almost 0 info on that module. Still searching...nice video TY
Hi AJ - I haven't seen one of those, interesting. Thank you for watching and commenting :)
If you turn the switch by the seat with the motor running wouldn’t you charge the house batteries?
It will, yes. I've done that a couple of times (by accident) :)
Very very helpful, thank you so much for sharing your knowledge!
How much power does your inverter draw at idle when there is nothing connected to it?
I'll have to look up the spec.
Nice job with your breakdown of the systems, I'm trying to get back on track with a project I've wanted to do for years, which is to install my ambulance inverter charger in my Tahoe, which over time became a solar powered set up , in my head, I believe it's a vanner ™ & I believe is in many ways identical to your Ames,,, ie; inverter/charger switchable & roughly the same power specs... I now have solar panels which should yield 100watts of energy to the charge controller, & would like to use them to power the inv./Chrgr. But when I went to connect the dots & see which piece to try to work out squiring & juz got caught up in Soo many variations and the technological gains and a new & wide range of capabilities & ways of using it,,,till my little intended couple of u tube sessions/research turned into more and more that I've gotta decide about, and I know my measley 100 watt setup is nothing compared to most and use of out there today from what I'm seeing and all these videos. It's what I managed to become able to afford and when it went on sale, I found a way to get it, I guess I'm just wondering , so that I'm not trying to save up for more than I need & making the expense any more than necessary since having to go on disability & huge loss of income, I have to be very extremely creative & patient especially to do any extra projects like I always have, but I'm blessed, & patience is a virtue!!
Sorry I've gone on so long , so , long story short, if you or anyone ur subs has any info or recommendations on products, parts,
Or 12v , 24v , 48v pros n cons,, batteries,,,, that might help me to piece together a quality smaller system with what I have so far... Would be greatly appreciated,,, and save me a good bit of my hairline...lol thanks 4 listening,,,🤔 or reading,,& any links or advice !!
Sorry if I missed this in the comments somewhere. If you wanted to charge your house batteries off your van alternator, couldn't you just flip the master switch while the engine was idling (or while driving) rather than hooking up the generator?
I could, but the charge profile isn't correct for my house batteries. It would work in an emergency.:)
In my box dome lights I have completely different light bulbs. Is one for shore power and other for battery?
Sorry using voice command. Supposed to say I have two completely different light bulbs
They are usually for low, and high dome. The low is one bulb, and high is both bulbs.
any idea where the house electrical disconnect switch is on the 2006 ford E450 / medtec is? there is a module disconnect toggle on the center console but I don't think this does the same thing
Many rigs (and mine) have the main disconnect switch, then a second toggle switch. The main and the toggle switch both have to be on to get power to the box. When you flip you toggle, does the box lose all 12v power? It may be triggering a disconnect relay...
So, if I want to keep the lights inside all the cabinets in the back, I just don't disconnect them right?
Yes leave them connected to your panel or, if you're removing your panel, add a relay to 12v.
@@TheCampulanceMan ok. thank you so much!❤
Great stuff - you left a bit of swearing at Lefty. on your cut
Another helpful video, thank you! Just a FYI, my ambulance is a 1996 Chevrolet 3500 7.4 with a Horton box. The 'On / Off ' switch on mine, next to the drivers seat, powers On everything and powers Off everything, both in the truck and the box. So when it is 'Off' it can not be started. However there is a 'module' Connect / Disconnect switch on the cab control panel that powers the box 'On / Off '
What did you do with the two battery cables that were wraped in gauze, are they now connected to the inverter? I was not clear about that part.
Yes those cables were for the inverter. I replaced them with new larger cables and connected them to the new inverter.
I've seen another rig with that type off switch - thanks for sharing that!
@@TheCampulanceMan Of the (4) four cables running into the inverter compartment on my ambulance, two are the 'shore power' in / out, and the other two, which are cut, one of those has 12v DC and the other is just bolted to the frame under the truck, is that the normal setup for an inverter connection? They appear to be 2/0 (00) or 3/0 (000) cables based on a OD measurment of 0.6625".
@@Nonthanburi2 Yes, from what you described those are the 12v cables that would connect to the inverter. The frame mount is negative and the other is positive.
I would recommend running both of those directly to your house batteries. No frame ground. The shorter those cables are, the better. You may have noticed I put my batteries right next to my inverter for that reason. The longer the cable, the larger they must be to minimize voltage drop. Good work tracing your wiring!
I have 1998 E450 Ambulance (McCoy Miller). I have the two battery tray in the box. I have a 700ma draw with the rig off. In the battery tray compartment there is a single stud where the battery positive is connect to two large gauge wires. I find that most of the drain is going to the sub panel in the box. I tried disconnecting that one from the system to see if the rig would start and the cab is dead. This rig needs both fat wires to be connected to the battery to start. My truck has a battery switch on the side of the drivers seat. This seems to control a relay. With everything hooked up the cab is dead without the battery disconnect being on. Switch it on and everything works. The 700ma draw is there regardless of the switch position. My Box has a fairly large PC board in a cabinet. There is always power to this board and I think this is where the 700ma is going. For some reason the box needs to be powered in order to start the engine. I was hoping to separate the two parts and am just getting into figuring out how. McCoy Miller doesn't respond to inquiries. I have to believe at some point there was build documentation for this truck. Some one didn't just free form wire it. I know its 22 years old so its likely long gone. My end goal would be to have a separate system for the running the truck. I would love to just remove all the ambulance electronics and start fresh in the box. The thing is all the lights in/out of the box are relay controlled by that big board in the box. And for some reason the starting circuit for the truck seems to be tied to the Box electronics. Any information source would be helpful. I could probably find a E450 schematic from 1998. That might help to figure out where the Box electronics are interfering with the starting circuit. We are in Northern Vermont and just started to mess with this project.
You made the statement that the "house" is separate from the "vehicle (van)". how are the lights for normal traffic in the "house" wired. Like turn signal, tali lights, clearance lights, backup lights etc.
Hi Charles - the taillights/turn signals/reverse are a part of the chassis wiring (van powered). The clearance lights are powered by the house batteries but relay triggered by the van wiring. The scene lights are house battery powered.
I love the dog 🤣
Fantastic information. Thanks.
Thank you Rita I hope its useful :)
The Campulance Man My husband is watching it for the second time. It will be very useful.
I just bought an ambulance and trying to tackle this. I have the switch in the seat like you said and my inverter is missing and I have no house batteries as of yet but in your video you you said that the switch will switch from van to house. Now I was told that I needed to turn the switch to both ( batteries) to start the truck. Is this not the case?
It depends on how yours is wired. The way I wired mine, the switch is between the 2 battery banks and connects them together. Most rigs, the switch is just to turn on the box, but I've seen different wiring methods.
do you still have main switch hooked up for emergency starting power in case starting batteries go dead just wondering ? may see you out there some day after get past some barriers going on in my life right now
Yes the switch is still wired like that, just in case.
@@TheCampulanceMan That's what I figured. I have worked on diesel ambulances but mostly Gms. When I was at a Chevy dealership. Best thing for a diesel is change filters often. Maintenance is way more important on diesel. The fuel is dirty and filters are big for a reason!
Great vid. Very much appreciated. Thanks!
Thank you Richard!
I bought two type 2 ford 350 vans. Neither van has a switch. One has 4 batteries (but identical vans in almost every way ) one has 3. The one with 3 has a 110 breaker box behind the seat. The one with 4 doesnt. The only switch that I have that I know of to control the systems is the overhead main power switch. It's confusing despite leader Incorporated did send me the schematics and I have novice level knowledge on 12 volt systems, i havent made sense of it. Any input appreciated
The best tip I have is to start tracing battery cables to find out how it's wired. They typically all join, then feed the 12v distribution cabinet and feed the inverter. Once you've figured that out, you disconnect them from the cabinet and inverter, add your new 2nd battery bank, and connect your new batteries to the cabinet and inverter.
Are you still in NY area ever? I have a few Ambulances and getting more for construction and maybe a few like what you have done. Just Awesome !!!
Hi Joel - I will be back in NY in the spring... where are you located? Any rigs with over 6' of headroom???
@@TheCampulanceMan I have 3 now and am buying 4 more. I will be converting to construction vehicles and you inspired me to try one like yours. I can check if any have higher headspace... I am in Middletown NY, Orange County.
@@solarjoelvinolas6468 If you're going to build one for a camper pick one with full headroom. I'm 6'0 and need about 5 inches more in mine...
@@TheCampulanceMan Cool, I will defiantly work with you since your videos have been great and I have only seen a few. I will check them all first before using them for the construction trade. My construction guys don't make me any money if they are hanging in the vehicle...
Hi Sorry if this was already asked somewhere, but what would you say is the total output in a day that your system would be capable of? I don't know much about electronics, I am looking at building an ambulance like yours out, and wondering if I'd be able to run a desktop computer and game at all.
You can run a desktop, TV, game console... anything you want. Just design your solar and battery system to do it :)
I have been lucky enough to find a company that does electrical and lighting for emergency vehicles in my town, amazing. The tech there suggested I keep my inverter, I think to use for shore power. We are going to sit down and go over everything but was curious about what you thought? Would you have kept yours if you had one? If so, why? I think my components for my solar system should all be new? (inverter, charge controller, batteries etc.) Thanks!
Many of the rig inverters are 1000watt, and I needed to have 2000watt minimum so I installed a 3000watt unit. Mine is an inverter charger so shore power still works with it. It depends on how much power you'll be using (air fryer, hot plate, microwave, etc) that will determine how big of an inverter you'll need.
Gotcha, I am planning on having 1200w of solar on top and I think I need a 3000w inverter/charger as well. I also plan on getting 4 - 200 watt hour deep cycle lithium phosphate batteries and of course a charge controller...all for the house solar system. I will also keep the shore power capabilities. I am of the same mind as you when it comes to not wanting to have to watch every watt I use! Having said that, would there be any use otherwise for the ambo's inverter?
@@anniewisecarver744 Only if you wanted to have 2 inverters. I would replace the original inverter with your new inverter/charger, then sell the old inverter on Ebay. They can bring decent money as they're typically UL certified units.
@@TheCampulanceMan, that’s what I’m thinking as well. Thank you!
Can you add solar panels and a charge controller and tie into the original system and use the stock ambulance inverter to power the house? I understand you run the risk of draining the batteries and not being able to start the van, just curious if it's do able
Yes, you can add solar to the ambulance batteries. You already mentioned the drawback, but it can be done. My friend Pam's rig is set up that way and she's been using it for a few years now, but she did have additional batteries added to the crank system so she has 1 very large battery bank that cranks the engine and powers her box/devices.
@TheCampulanceMan right on! Thank you for taking the time to reply. I am looking at picking up an older k3500 ambulance sometime this week. Your videos have already been so incredibly helpfull
Hi David!
I just purchased an Ambulance as well and in the process of converting it.
My question is that you said a few time to keep the house and truck batteries completely separate, but what about being able to charge your three house batteries VIA the alternator while driving? I'm also changing over the shore power plug in to charge the three house batteries as well, So my though is I can charge my batteries three way, while driving , with shore power and with solar... Let me know what you think about this! Id love to hear.
Hi Erika - yes you can connect the 2 systems through a battery bank charger, that gives you the ability to charge from alternators if desired. That will still keep the 2 systems seprate from each other :)
My 94 e350 has two master switches. right side of seat controls the house. Left side of the seat shuts the whole vehicle down. I stripped the house of everything. Re-insulated the house. Took out lights, air conditioner and heat. All cabinets, bench, seat, cabinets and counter top. Cut and removed much wiring and have a lot to go. I have two battery's under the hood. No inverter. I have installed shore power but don't have house battery yet. Solar down the road sometime. I know how I want to finish but cost is more than I planned so slow going. I have been following you as I see you are from Rochester, ny. I am a retired police lieutenant from Watertown, ny. I am in Kansas but legal resident of South Dakota for tax purposes. I will have some more questions as I go. You are the one source I have found, re ambulance build, that has been helpful. My girlfriend plan to be full time at some point. Later.
Hi James and thank you for watching. Sounds like you went real deep on the customizing!! If there's anything I can help with let me know and have fun on your build!!
Hi David. After watching this I went out to check my ambulances switches. The one on my seat kills all power to the van and house. There is a switch on my counsel that says master, that kills the house only. Mine is a 97 ford e350. Yours looks alot like mine. I'm just shorter i think.
Hi Wille - I've seen a lot of combinations of switch operations and yours is interesting. So the seat switch disables engine cranking also?
@@TheCampulanceMan yes. Kills the entire truck. Can't start it.
How long can you run your air conditioner on your batteries?
All day and evening until the sun starts to set. Then the batteries start to drop. They stay at 100% while the sun is on the panels.
Thanks for inspiring me to buy an ambulance! I am converting it into an office/moving van for my nonprofit. I bought a 2000 Ford E-350 turbo diesel type III ambulance yesterday. I don't think I am going to have to make many changes to it, it just needs some minor body work, painting and cleaning. I will probably add solar panels later this year. I am having a hard time finding replacement keys for the outside storage lockers. Any ideas? I also need a replacement round rear brake light. I hope you plan to visit Hawaii soon, if you do, let me know. You can stay in my Campulance! Aloha!
An ambulance makes a great platform for businesses - great choice! The locks, if like mine, are standard type and can be replaced as a cylinder or the whole handle with lock, for low cost:

Super helpful!!! Thanks 🙏🏻 🙏🏻🙏🏻
thank you for the informative videos. Just wondering when you mentioned the original wiring for the fan and a/c in the box is there a productive way of using the existing air ducts from the original install with your new heater or new a/c units? Thanks (maybe a good topic for a video)
