Between Eric here, Eric O and Eric the car guy, if you name your kid Eric they will grow up to be Awesome Auto Technicians. That's just science right there. Awesome work again!
Hey use an Infrared Camera to find parasitic draw... You can see what fuse and or module has a load on it from the temperature difference... its pretty fun and very fast to find the suspected circuit..
Nicely done my friend finding a parasitic draw in a Ford is so difficult because of the modules waking up all the time. You showed incredible patience waiting for everything to go back asleep thank you awesome video
@@fredsalter1915 internal short but the op has the idea of a true solution. I actually did this on a GPS system. I installed a relay that was triggered by the ignition switch, usually these modules have direct power and another power circuit powers them on internally. A short would cause amp draw like this, very typical with radios too because they have direct current and ground.
And if you see 19:36 the dark spot on the right of the DVD has like 2 small purple lights. Which I think are the Infrared LEDs to read the remote controls input. Indicating it was on
Thank you for the video. If you don't feel like voltage drop testing the fuses while searching the draw you may want to pull fuse by fuse but not put them back in until you pulled all of them. That way you'll avoid waking up components and you don't have to wait for them to power down.
Great detective work, very educational and entertaining. The heat and humidity in cramped spaces must have been unbearable but you overcame it and kept moving forward. You are doing a good job!
When I was dealing with the same problem, I just had made leads long enough to take multimeter in the car with me. So I didn't need to have a helper. Additional leads voltage drop was irrelevant.
As Murphy dictates, you start removing fuses at one end, but Murphy makes it that you should have started at the opposite end. I feel for you Eric. It must have been a real pain... An excellent fault find and diagnosis... WELL DONE!!! 10/10
Eric, Excellent job is finding the parasitic drain. You did a fantastic job in explaining the step by step method of finding the problem even a novice would understand.
I'm glad you said something about letting Fords time out for about 40 mins to an hr. Service data says this, and covers all vehicles from about '00 to about '11. It has been my experience that the smart junction fuse box battery saver relay sticks, and will cause about a 400mA draw. Sometimes it's just the relay, other times the magic box. If so, the box must be programmed to make the remote key fob work, even with the same P/N. Glad you found the issue!
Fantastic as always Eric! Try looking for voltage ACROSS fuses, so you don't need to disturb them! (I'm out of commission for a short while. No vids until I get my computer data recovery)
typical voltage drop 5mv per amp across 15A fuse . Measuring parasitic currents this way can be done, but you need a voltmeter with 50 microvolt or better resolution .
30 yrs ago, a VW convertible had a parasitic drain on the battery. I was by myself, so I made long leads, hooked up a volt meter, battery was draining .01 volts per minute. I followed the exact same process. Battery started at 13.31 volts. I pulled every fuse, no change. Battery was down to 11.55 volts. I pulled a non-fused, grey wire. Voltage jumped to 12.55 volts. I checked to see what did not work. I did not have a wiring schematic. All things worked. Business colleague later told me that the light that came on to indicate a gear shift was required no longer worked. (it was a stick shift). Business colleague had brought his daughters vehicle to a number of electrical shops in Jacksonville, Fl. He asked me to check as a favor.
This case was hard for Eric being hot, upside down. Great video! Keep them coming, I am learning a lot. If I am not mistaken, the IR emitters for the wireless headset were illuminated.
Extremely useful video. You provide an incredible service to your viewers. Now I know why my back hurts so damn bad as I have contorted myself in very much the same way trying to repair our family vehicles. Thanks again. Great job. Thanks for reminding viewers about "waking up' modules and how to avoid doing so.
Incredible troubleshooting! Sir you need to stop apologizing, there is no need, because you do great work, and fantastic info and knowledge to the rest of us. Keep it up if you enjoy it 🤩
I feel for you with the extreme heat, cramped and uncomfortable quarters, all while trying to do the work. My back's always sore after working under a dash, or around the kick panel areas.
Thanks for making this video. It was the same issue draining my battery. There must be an internal issue with these overhead dvd players. Important thing to know is that fuse 21 is the instrument cluster. At first I thought this was my issue. This circuit takes 40 minutes to go to sleep. If you pull the fuse leave it out and test the other fuses. If you put it back in you will have to wait another 40 minutes for it to go to sleep again.
Back in the day, information and technical training was scarce and at a premium price, the videos have helped me a ton as I'm still active in auto repair, just not in dealer setting, nevertheless great full for all the folks sharing, but one question I hv do videos interfere with techs and there ability to make billable hours, or as it appears not much of an effect, based on how busy u still are
Great video Eric. I was going to suggest trip the door latch/actuators so the vehicle “thinks” the doors are closed, but you did it before the end of the video. Always fun to record in one hand and remove DVD from ceiling with the other hand. Thanks for the video. They are always educational!
Great job Eric , I wonder how you go about charging for this type of job ? , looks like from start to finish its at least 4 hr ......here in Canada auto shops charge up to 100$ per hour , thats about 500 BUCKS !!! with taxes , fees , shop supply's etc.
You are no doubt very gifted . however in this test with the fuss"s do the same test but DON'T put the fuss's back in leave them out until you find the problem . by reinserting the fuss you wake up modules deny it power until you find the problem . i hope i helped cheers !
Great video! I was following your wiring on Mitchel. Maybe you should have started with the door latches on all 4 doors closed but the doors open. That way you have access to the inside of your vehicle. Also make sure that it's the supply wire to the fuse box that's taking the amps and not any other line.
After watching this I am so happy to know it’s not just me. 😂 The batteries in the voltmeter died, the position you had to work in sucked, it was hot, etc. That’s about how it always goes for me.
Hey Eric keep up the great content. Where can I find a wiring diagram for a 2010 Buick LaCrosse. Having front window problems and radio and lights not turn off when door opens.
one tip after you found the correct fuse hook the meter to the fuse box where that fuse was that way if you wake up any modules you want have to wait for them to power down as meter hooked to the battery cable
My 04 navigator is doing the same thing. I’m going to pull the 4 fuse and check since I can hear the dvd player making noises sparatically. Wish me luck.
Did the replacement PCM come pre-flashed? If they are available pre-flashed it would be good news to us DIY'ers. There are few qualified independent shops like Eric that can do this. We would have to depend on a stealership that won't do it unless you buy the PCM from them at a ridiculously high price and then charge you an eye to re-flash it.
@@lordjaashin the same ones Eric struggled with here, before starting I would prep all the doors by setting up the latches to have the door open but not have the interior lights on. Many times this meant setting up the trunk or rear hatch in the same way so that I had full access to the interior and didn't have to reset my sleep timer by opening a door. Also when possible I would test by measuring voltage drop across a fuse to see if a circuit was active rather than unplug and reinstall fuses which would wake up modules and cause me to take more time on a diag than necessary. Another thing that really helped was taking multiple pictures of the fuse box before I touched anything so that I could at least get it back to it's original starting point. Although they don't always show up with everything in the right place at least it wouldn't be my fault something was in the wrong slot. I had to implement these changes after a couple diags took me hours that they shouldn't have. Also Uni-t has a handheld amp clamp (UT210E) that is awesome for finding even very small amounts of current flow and it's like $50 using that I didn't have times where my connection to the battery would get disturbed and reset the sleep timers and I didn't take the risk of popping fuses inside my meter since some of those are not the easily found or easy to replace kind.
@@lordjaashin I truly don't think you'll be disappointed it's a really good tool and it has more applications than just parasitic draw diags I've used it many times for charging system diagnosis as well. Good luck with it
@@jwilkers1 I keep seeing the comment to test across the fuse. Is this either side of the fuse or from the fuse to ground. Sorry for the extremely uneducated question. Just trying to understand. Thanks

@@ErikTheVikingMechanic 🤣
I felt your pain upside down in that car. I always open doors and latch them at the start . Once you established the cause it was easiest fix ever. 👍
Hey use an Infrared Camera to find parasitic draw... You can see what fuse and or module has a load on it from the temperature difference... its pretty fun and very fast to find the suspected circuit..
Its amazing to watch you disconnect wiring with one hand and still make the video with your other hand.
I want to appreciate you and Oz mechanic. Thank you all for what you have done for me.
after 48 years of strugling with electrical i purchased a flir tg167 first time i used it i found a glowing alt. i am sold. you rock my brother
Nicely done my friend finding a parasitic draw in a Ford is so difficult because of the modules waking up all the time. You showed incredible patience waiting for everything to go back asleep thank you awesome video
So many gadgets, so many problems... Luxury comes at the cost of dependability. Excellent video. The thumbnail photo is fucking hilarious.
If the DVD unit is still operational, perhaps you can install an on-off toggle switch on the housing to disconnect the power when not in use.
Maybe a firmware update woulda fixed the DVD player. It seems like it was not going to sleep when the car was turned off.

Man really great video. My kids mom having issue with her battery draining every two days. I told her she need to drive the truck.
Like your approach to isolating the problem.
You did it right, good diagnosis! It's those 45 minute waits that are tough, and Ford's Smart Junction Box can be real joy to work on.
Fantastic as always Eric!

From UAE watching, You did well man... I like the way u patiently sorted things out. Nice one
I have a 2005 LN and it just started doing this after a battery change. I don't have a DVD player in the Base model.
Thanks for this!

Exactly because of this video i did my drain check on my Vw mk4 👍🏻
Learned something new today. I really like your train of thinking....
Muy interesante nunca pensé q ese sería el problema nunca me a pasado gracias por tu tiempo para enseñar .
Eric keep up your good work you help alot of people .
Open circuit it, I do it all the time. Nice Ammeter guys

Great video bro,my Navi is doing the same thing most likely is the same problem...👍👍👍👍
Bad ass dude! bad ass way of diagnosing the problem
Great job
Remember less is better. They want us to buy all this extra crap with causing more problems later. I miss the 80's/90's

Nice find Eric. Go get something cold to drink and cool off. Stay safe and well Artie the heat is bad up here in New York also. 👍

Experience diagnosis amigo nice video. Pwro. Tengo una preguta es normal kw puedes kitar y poner fusi Keno se tiene ke medir con voltmeter

wow working in that heat.thanks
So much fun watching you brother!
Very impressive work.
You need an amp hound. You can just touch the top of the fuse without pulling the fuses to see the amp draw.
Awesome work. i never would have thought that to be an issue
Nice troubleshooting 👏👏
You the best from Richard in the UK love the Chanel
Great diagnostic. 👍
Great work Eric. I would recommend that you get a nice garage to take it to and get an air conditioner for it so you can work in comfort 😉
My new favorite channel🔥
This just goes to show how technology is coming and going faster and faster.
Awesome job guy's, thanks for the training!
fantastic job Eric
Love your trouble shooting skills man.
I didnt quite understand the current meter setup.. How was it connected to the battery?
Thank you. Very entertaining
Great job Eric and Great video thanks for sharing.

No need to replace battery terminal, just use a post shim. Got a video on my channel of how that works.
Would it be OK to use an Amp clamp rather than disconnting the battery cables and connecting and an Amp meter in series?
You could but sometimes can be inaccurate, connecting in series is a exact reading.
Hey man thank you for this video !!! Appreciate your time and effort

question- i have a P0300 code on a 2010 chevy Equinox, how bad is it and have come across this problem before
Nice video as always Eric 👍👍
Oh you are in Houston hey if I ever need mechanic service how do I get a hold of you??? I live here in Houston as well
Thanks for the video brother
Good idea to tape to the door buttons down or trip every latch first even on boot and bonnet, yeah yeah, I’m an Aussie, ok hood and trunk.
