@JerryRigEverything Hey Jerry can you reply me some questions....can you give me your old iphone which were preety durable during your durability test ??? Please
Our advise, as an EV Manufacturer Start-up, would be to isolate the charger from the CAN Bus and connect to it with a laptop in order to see the messages that it is broadcasting. If there is a fault other than the communication, you will know. You mentioned this charger is from Siemens, but I'm pretty sure they are just reselling a TC Charger as it looks exactly the same as the one we use (but at a lower voltage). Those charger needs an input from the BMS, normally as a CAN message to start charging. There are 2 messages, both on 2 bytes, one for the targeted termination voltage and the other for the max DC current. Since this particuliar charger handle the EVSE (pilot and prox) itself, it might be a little different, but not that much as the BMS must be in control of all current flowing. Once the charger works as isolated form the CAN bus, like other suggested, plug back on the networks just the BMS to make sure it is still working. Maybe you have a bitrate difference between two devices. Then, you mentioned in the video that you checked the pinout of all the plugs so it should be good but a fault would be thrown if the DC connector was inverted. In resume, I think you pinpoint the trouble correctly to the CAN bus, so I would check that first with a laptop and an USBCAN or a CANALYST and have a look at what is running on this bus. Hope this helps. I'm sure we can be of more helps with more details on the build, if needed.
@@electricsupercar Also these TC chargers won't do anything if there is no DC voltage detected. There might be a contactor between charger and battery pack (or it is the main contractor for example) and if that doesn't close, the charger won't see the high dc voltage and not do anything. I don't know if this is equal to a TC charger, but if it is, it probably has some pcb in there that handles the EVSE communication. That pcb might or might not be connected to the CAN bus and it likely be powered by the 12v output of the AC charger. Lots of assumptions but I hope it helps.
In my experience just smash a bunch of electronics shoplifted from a thrift store and tape whatever resistor you hack out of there in place with a section of silicone beverage straw covering it. It's either the red wire or the blue wire. Just try both. Should work. Worked last time
I have a tip for you. Your walls might have some hard surfaces, but your roof is the biggest unfurnished surface in the room. Hanging up some large acoustic panels there will definitely improve the reverb
Note that if you want something less expensive than these felt pads, you can use quilts or sections of quilts. That's a common trick in the voiceover community. Of course, quilts wouldn't look as nice as the felt pads, so there is that trade off.
@@electricsupercar I work with audio and can tell you that any fabric on the ceiling will help and you dont need to cover it all. Get yourself some cheap thick blankets and nail them up there

Nope, it is in the video. It is very common, new youtubers start with the image and audio is an afterthought. When in fact, audio is more important than the image in most videos. You can test it. Mute audio and see how much you can understand what is happening. Then let audio only thru, minimize the browser, open another tab. Can you follow what is going on?
My first thought would be to disconnect everything from CAN bus and start with just BMS and battery. If that works then add more components to bus, see, when it starts to fail. I hope the batteries are fine. Good luck!
Just saw your supercar build project today ... nowni cant stop watching all of your videos ... Congratulations bro... from one build junky to another .. your simply awesome bro... great ambitions with the drive to match

Make sure the termination resistors or terminating nodes are at the physical ends of the CAN network. Also make sure the connections go from node to node to node etc., no ring, star or stub connections. If the slaves can auto detect the bit rate make sure the Master has a fixed bit rate. Any node that cannot auto detect set the rate to match Master. Also make sure every node has a unique ID. Hopefully atleast one of these gets everything talking.
With a can analyzer i always recommend canalyzer with a can case its a good start, you need to assert that all units on the bus are talking with the same bus speed otherwise no messages will get through. Setting up a can network will be tricky and you might need a can master that can translate all those messages between the different systems and can profiles. I spent 4 years peograming EV can networks for inverters, it gets messy quick
Love your channel and content, I would suggest that you use a Lavalier microphone, your channel is large and it would be a good addition for high quality audio.

Nice to see you working with Zack! You may want to do some research on connecting stranded wire. My understanding is that crimp connectors should be used, not solder. The issue is solder turns stranded wire into solid wire which when flexed eventually breaks. That's why stranded wire is used in automotive applications where the wire is constantly flexing.
I’d love to see a video, once everything is fixed, on what you would have done different to avoid these issues. Whether it is different parts, earlier testing in the build, or different system all together. Thanks and I love the content.
I was just wondering a couple of weeks ago what Zack has done to this military Hummer. I thought he liked the Rivian so much he ditched this car but great to see it being worked on again. Love to see this functioning the way it was intended (tough off roader, occasional road car/truck).
Cool intro! Somebody skipped the 'ugly, but working' on a test bench step, and the thankless 'document what works' step, and went direct for the 'beautiful build' step. You deserve an award for stepping in with knowledge and a calm assessment of what needs to get accomplished. It's actually 2x as hard to find and resolve design problems after all the quality build efforts have been applied, tightened everything up, and closed the harnesses. An ohm measurement is nice but you need to remember that the time domain aspects of the data bus design requires the actual locations of the resistors to be correctly placed at the electrical ends of the CAN bus. If you really don't know how the bus is routed use a TDR (time domain reflectometer) to assess the bus line, best plan: terminator, VCU, Display, BMS, Charger, terminator. Configure each terminal # correctly, sometimes the default terminal numbers are same or the VCU controller is talking to the Charger as #1 and the Charger thinks it is #4 and the BMS thinks it is #1. etc. I always get the VCU and Display working, then add the BMS, then add the Charger.
This is the first time i watch your videos . I really am impressed by the way you explained everything , it was clear and easy . Can't wait to watch more educative videos . Keep up the good work
I was a broadcast engineer for years, one particular model of HDTV transmitter used CAN Buss for communications between control boards, exciter amplifier, and final Power Amplifiers. I recall a CAN Buss wiring getting a few wires shorted on the bus wiring, which took on the communications IC Chip on most of the PA " power amplifier" modules. I basically had to go online and order new IC chips and purchase a soldering station for surface mount Integrated Circuit soldering, and replace approximately a dozen of these ICs to gain back communications on the CAN Buss. I'm just putting this info out there, this all started because of shorted wiring in the buss wiring. Don't know if this is what your problem would be, but for what it's worth.
Really nice of you to fix the jerry rigging.... you should post an affiliate link (if that's possible) to that magnet/grabber tool you had. I've never seen anything like that. Would love to get one.
I am an EV battery Pack design Engineer and have also worked on the power electronic of EV, you should purchase a CAN Adapter to log and record CAN message on a Open ended software like BUSMaster and check if your OBC is sending and receive CAN messages as per protocols mentioned by the vendor. 1) Make sure you are sending all the necessary CAN messages to OBC ( On board charger ) as per OEM instructions. 2) Receiving the feedback CAN messages and no fault code is detected. ( Please refer to CAN data sheet of On board charger ) 3- You are using J1772 charging socket and it used CC and CP pins to communicate with OBC please make sure there are also properly connected. Just let me know, I will be more than happy to help you guys out in this project. Kudos !!
Thanks for the comment! At the moment I am troubleshooting with Orion as well as evolve. It seems that the CAN is communicating. It seems that the BMS is not happy about something so...still trying to find out what.
@@electricsupercar I have used Orion BMS for EV prototype battery pack, I am completely aware about its software also. You can email me the issue you are facing with Orion BMS. I hope we could solve this issue ASAP! just let me know. Regards
Since your pin outs are good I would start checking that all the grounds/neutrals/returns are solid. PLCs and drives are really finicky when it comes to cable noise or bad grounds. Edit: To be more clear, anything that is communications should be shielded cable that is grounded. It was a necessity in the lehr loaders I used to build and install in glass factories. I’m not sure how necessary it is in an EV but it is a high voltage system so it’s just my 2 cents.
Great job. Thanks for doing this! The Orion BMS2 does have two CAN networks, and I think one is internally terminated, so I agree that that probably shouldn't be the error at this point. Two things I'd like to see you address are the communication baud rate and the HVIL connector setup for the Valeo Siemens. So far, I haven't found any guidance on how the HVIL should be integrated, though my assumption is that the charger is simply reading an open versus closed circuit loop.
I was wondering if there are people who actually watch these videos, these types of videos are trending in the most watched ones Nobody can interfere in anyone's life!
I've worked with CAN bus before and I had a ton issues with it. Heres a few ideas: CAN ID collision? It does happen from time to time. Depending on the protocol it could be a 1/255 chance. Perhaps the frequency is not the same on both sides? It could also be mismatched protocols (regular frame vs extended frames) It could be a dead transceiver on the charger so trying to isolate the charger and talking to it directly can help diagnose it. Improper grounding? Unlikely but try adding a grounding wire between the charging box and the VCU.
Id probably try a few things: an oscilloscope on the can network to check on the signal Check can for is the right messages are passing and any trouble codes Check sequence of operation and interlocking on the high voltage DC side for any issues (like contactors needing to be closed first so the charger can see DC voltage from the battery in the right range for a healthy battery, many chargers require that before they start re check the can wiring matches specs, I know he mentioned using some wire designed for can but the branches of the trunk didn't look like they were using that special wire, with relatively long and high speed data connections (as in more than a foot or two and into kilobits per second) things can get interesting and seemingly minor issues with wire become major problems, shielding is important, as is lengths, especially of any branches, but also things like characteristic impedance which is also why those termination resistors are needed, if you have a mismatch of the wires or miss a termination resistor the signal will bounce off and back down the wire interfering with itself, I don't know the exact specifics for can in particular but I'd expect that branch for Jerry's laptop should be terminated whenever a can device isn't connected and I would not be surprised is the characteristics of the branch wires were wrong and creating reflections at one or both ends of each branch due to impedance mismatch. I'm in IT and deal with a lot of non Ethernet "networks" for various things and I've seen a few of these types of issues crop up, multi drop bus networks (which can is) in particular can be very picky and if you only have worked with point to point or very slow and/or very short cabling (in signal time vs speed of propagation, so short here means very short, and is inversely proportional to speed, in high speed terms for things like connections to ram I side a computer or inside of computer chips, long might be well under a foot) you may not realize how important some seemingly minor specs can be.
Have you measured the Can H and can L with an oscilloscope to check if the signal is mirrored and if you can actually see the voltage oscillating? I would assume that the can speed is around 500kbps so make sure to calibrate the oscilloscope properly. Good luck!
Don't make it to hard on your self, just get a CAN sniffer and see if the messages go over the network. No traffic = something's is wrong with the wires.
Yeah, I would check the config in all controlers that they are communicating at the same CAN speed etc, if they have different speeds, say 250kbps and 500kbps things will not work. :p And are the ends of the trunk terminated? If not put in resistors 120 ohm in both ends will help with signal, although I would think it would work on such a short run anyway..
Normally I wouldn’t nitpick, but since you care about audio, the mic’d sound in this video is often panned to the right ear, the voiceover is boomy and distorted. I still thoroughly enjoyed the content!
Oddly I hate the audio on Jerry rig everything to the point I don’t watch his videos. It sound fake and overproduced to me. I have such a strong reaction to it.
When I built an electric JetSki I had soooo many problems with the charging. It was the same Thunderstruck motors box. Ultimately it had to do with grounding the charger itself to the negative terminal of the 12v battery. As well as plugging the box into my computer and programming the charging settings. Anything helps 🤷🏽♂️
How odd - there really isn't a neutral in the J1772 connector, L1, L2, and Ground. Maybe Ground is supposed to go on top of that charger connector. Weird European charger stuff! Nice first video. I'm guessing you're right about the CAN bus being the culprit.
Not weird european thing, thats a US market specific connector. Europe uses a different connector. The US one is often known simply as J1772 or J1772 Type 1. Europe uses J1772 Type 2 or "mennekes" which has 3 phases and a neutral. For US usage. You can use L2 interchangeable as the true L2 in a domestic split phase system or as a neutral in either industrial 220V single phase or domestic 110V single phase. The standard allows both and the onboard chargers are designed to tolerate both.
There was one thing with the locking pin where some plugs can sense the opposite, I am paraphrasing but wonder if this could be related to a locking pin sensor, detecting whether the pin is fully attached or not.
Great video!!! The conceptualization and scripting was spot on, and not every one understands the work that goes into production, editing and ULing these videos for commenters to criticize your every waking move, after all you are just someone that builds EVs for a living, integrating not necessarily meant to talk to one another parts into some homogenous friendly group that plays well together and tell you that the can bus is not a Token Ring or that the can bus needs ending resistors that are actually at the ends....
Check Unified Diagnostic Services (UDS) using CAN. Use CANalyser and CANape for Diag. It will provide you the error codes and possible fault(s). I do that all the time with most of the Electronic Control Units (ECUs) of a car. Diagnostic and Communication via CAN, CAN-FD or LIN or any of those expensive comms(MOST, Flex Ray and Ethernet) is a headache. I always follow the boot sequence, diag session (Default session), then check for Read Diagnostic Trouble Code (DTC). Check the response code for Read DTC.
I'm so interested in the electric hummer working and I can only support you guys with prayers cos I have no clue what you need to do to make it happen. Good luck and best wishes guys. I'll be watching with keen interest and by the way Happy New Year 🙂. Subscribed 👍
Yes I drove a 1972 Dodge Challenger for 15 yrs and it didn't catch fire 🔥 because the wiring was done perfect! An as far as I know I got the most miles out of dodge Chrysler challenger! An everyone else didn't drive the car or it Burned! Which is kind of cool I think that I've started thinking I should convert it into a EV called the radio station and discussed on air with the NPR PBS host who was super nice and added she'd love to drive in one of those!
As others have commented already I would try components in isolation. I have had issues in the past with message IDs clashing, checking the broadcast message IDs from each component individually would help identify any clashes. You mentioned checking continuity, but have you confirmed the BMS is waking using the output from the charger?
My suggestions: #1 Check the grounds. Seems so many vehicle electrical problems caused by bad grounding. #2 Put an analyser on the CAN bus and see what the charger is sending. The fault code should indicate what the problem is. Given Jerry’s previous comments about inability to see metrics on the display, I would suspect the CAN bus connections / configuration.
There's something off with the audio. Cam u please combine stereo to mono wherever possible because the left channel has way too much volume than the right. Headphone experience isn't good
New to the channel followed watching the whisper project. It's a really interesting channel. keep up the hard work. I look forward to seeing some more awesome builds
Connect a oscilloscope to the Can Bus and look if data packets are being sent over the network. Look at bias voltages as Can Low should be at 2.5v nominal and pulled down to 1.5v and Can High should be at 2.5v nominal and pulled up to 3.5v. If your voltages are lower it usually means a bad power feed to a module that communicates on the Can Bus and if you have elevated voltages there is a module with a bad ground that communicates on the Can Bus. That is the only way to truly troubleshoot a Can Bus system. A multi meter leaves to many variables when testing Can Bus as you need to see the data packets. Make sure the waveform has good square waves with a higher square wave at the end of every message. Make sure the wave forms are not leaning into a direction but pull straight up and straight down. Hope this helps
Your video production is pretty good although I think the biggest room for improvement is microphones. A good mic could dramatically improve your video. I'm not confident enough to give a recommendation, but there are tons of resources online to get recommendation at any budget.
@@NvidiaRTX5080 Ya thats true for some reason i assumed it would be wired in 4.2v but that would not make sense for any electric motor. It may just be 1 cell that is faulty and you will not know unless you tested every cell individually or if the computer was smart enough to display a error with a pack of cells then your stuck checking every one yourself. Because it took him so long to make the hummer chances are the batteries got really low and is causing these issues. Its the most common problem with lithium batteries and its the same reason why samsung phones are popping open because of the batteries inflating. Charge your batteries! 3.7v for long term storage.
I actually saw this when Zack announced it, and had already given it a thumbs up, but sadly didn't follow it up with the rest of the videos. I will immediately remedy that now, lol.
Great video! Listening on headphones, the first 3 minutes your right channel sometimes sounds like you're underwater, it's only the low frequencies, while the left channel sounds fine. Maybe you didn't notice before, maybe it's a known issue, just thought I'd let you know :)
Thats a huge inprovements as i have been following this project from the day it started and i am really enjoying and learning a lot of things here keep up the good work definitely waiting for a new video
I have been intrigued in doing EV conversion, and JerryRigEverything have been delivering every nuance of the conversion job on his converted military Humvee. I will be watching the incoming videos to see how you can fix the Humvee and get it back on road.
You could build a short extension cable for your can bus connections then sniff the traffic. You can sniff with a scope. I also recall that if you have access to the individual wires you can use a clamp on sniffer. Of course your can topology is important, but I recall the owner already me noted that.
The felt made a nice difference to the reverb in the room but I'd add some square block corner foams - that'll cut down but still leave enough to enjoy music
Finally all caught up in the whisper project videos. Nice job tackling the HUMVEE. I think in the next video we will see it driving out of your garage.
I know that I'm late to this party. Anyway, in the industrial applications where we had communication issues, I would rent an oscilloscope that has a CAN decode function and analyze the packets in order to narrow the issues down (to a device or a configuration issue). Don't know if that is an option for you. There's also some good CAN to USB converter and analysis software out there. It's just that the Scope served multiple purposes, for my use case. Good Luck!
Lol! That intro is amazing!

@@electricsupercar I have used Orion BMS for EV prototype battery pack, I am completely aware about its software also. You can email me the issue you are facing with Orion BMS. I hope we could solve this issue ASAP! just let me know. Regards
@@syedahmedhassan7951 what is your email?
@@electricsupercar Please check electric super car email, I have left a note on that email.
Since your pin outs are good I would start checking that all the grounds/neutrals/returns are solid. PLCs and drives are really finicky when it comes to cable noise or bad grounds.
Edit: To be more clear, anything that is communications should be shielded cable that is grounded. It was a necessity in the lehr loaders I used to build and install in glass factories. I’m not sure how necessary it is in an EV but it is a high voltage system so it’s just my 2 cents.
Thanks for the comment!
@@electricsupercar make sure all the firmware/software is up to date… Should probably start with that first
Great job. Thanks for doing this! The Orion BMS2 does have two CAN networks, and I think one is internally terminated, so I agree that that probably shouldn't be the error at this point. Two things I'd like to see you address are the communication baud rate and the HVIL connector setup for the Valeo Siemens. So far, I haven't found any guidance on how the HVIL should be integrated, though my assumption is that the charger is simply reading an open versus closed circuit loop.
Thanks for the comment!
Great video, love the intro!
Was it only me or was most of the sound only from left channel?
Also, why not connect CP and PP to the orion Bms?
I was wondering if there are people who actually watch these videos, these types of videos are trending in the most watched ones Nobody can interfere in anyone's life!
Thanks for the update! Solid work on that troubleshooting
No problem 👍
I've worked with CAN bus before and I had a ton issues with it. Heres a few ideas:
CAN ID collision? It does happen from time to time. Depending on the protocol it could be a 1/255 chance.
Perhaps the frequency is not the same on both sides?
It could also be mismatched protocols (regular frame vs extended frames)
It could be a dead transceiver on the charger so trying to isolate the charger and talking to it directly can help diagnose it.
Improper grounding? Unlikely but try adding a grounding wire between the charging box and the VCU.
Thanks for the comment!
Great intro! Just a note, your audio is skewed towards the left channel and the video is unwatchable with headphones
Good to know!
Id probably try a few things:
an oscilloscope on the can network to check on the signal
Check can for is the right messages are passing and any trouble codes
Check sequence of operation and interlocking on the high voltage DC side for any issues (like contactors needing to be closed first so the charger can see DC voltage from the battery in the right range for a healthy battery, many chargers require that before they start
re check the can wiring matches specs, I know he mentioned using some wire designed for can but the branches of the trunk didn't look like they were using that special wire, with relatively long and high speed data connections (as in more than a foot or two and into kilobits per second) things can get interesting and seemingly minor issues with wire become major problems, shielding is important, as is lengths, especially of any branches, but also things like characteristic impedance which is also why those termination resistors are needed, if you have a mismatch of the wires or miss a termination resistor the signal will bounce off and back down the wire interfering with itself, I don't know the exact specifics for can in particular but I'd expect that branch for Jerry's laptop should be terminated whenever a can device isn't connected and I would not be surprised is the characteristics of the branch wires were wrong and creating reflections at one or both ends of each branch due to impedance mismatch.
I'm in IT and deal with a lot of non Ethernet "networks" for various things and I've seen a few of these types of issues crop up, multi drop bus networks (which can is) in particular can be very picky and if you only have worked with point to point or very slow and/or very short cabling (in signal time vs speed of propagation, so short here means very short, and is inversely proportional to speed, in high speed terms for things like connections to ram I side a computer or inside of computer chips, long might be well under a foot) you may not realize how important some seemingly minor specs can be.
Have you measured the Can H and can L with an oscilloscope to check if the signal is mirrored and if you can actually see the voltage oscillating? I would assume that the can speed is around 500kbps so make sure to calibrate the oscilloscope properly. Good luck!
Nice! Thanks for the comment!
Don't make it to hard on your self, just get a CAN sniffer and see if the messages go over the network. No traffic = something's is wrong with the wires.
Yeah, I would check the config in all controlers that they are communicating at the same CAN speed etc, if they have different speeds, say 250kbps and 500kbps things will not work. :p And are the ends of the trunk terminated? If not put in resistors 120 ohm in both ends will help with signal, although I would think it would work on such a short run anyway..
My left ear loved this video
To reduce the echo, those pads must also be placed on the ceiling. Great video 👏.
That would be awesome!
Im here from JerryRigEverything channel, new subscribers your channel 😊
Welcome!!
Normally I wouldn’t nitpick, but since you care about audio, the mic’d sound in this video is often panned to the right ear, the voiceover is boomy and distorted.
I still thoroughly enjoyed the content!
Oddly I hate the audio on Jerry rig everything to the point I don’t watch his videos. It sound fake and overproduced to me. I have such a strong reaction to it.
Got it! Thanks for the comment
I’m 99% here for the content, I wouldn’t have even mentioned it, if it wasn’t for the segment about buying acoustic foam to improve audio.
When I built an electric JetSki I had soooo many problems with the charging. It was the same Thunderstruck motors box. Ultimately it had to do with grounding the charger itself to the negative terminal of the 12v battery. As well as plugging the box into my computer and programming the charging settings. Anything helps 🤷🏽♂️
Thanks for the comment!
How odd - there really isn't a neutral in the J1772 connector, L1, L2, and Ground. Maybe Ground is supposed to go on top of that charger connector. Weird European charger stuff!
Nice first video. I'm guessing you're right about the CAN bus being the culprit.
Thanks for the comment!
Not weird european thing, thats a US market specific connector. Europe uses a different connector. The US one is often known simply as J1772 or J1772 Type 1. Europe uses J1772 Type 2 or "mennekes" which has 3 phases and a neutral.
For US usage. You can use L2 interchangeable as the true L2 in a domestic split phase system or as a neutral in either industrial 220V single phase or domestic 110V single phase. The standard allows both and the onboard chargers are designed to tolerate both.
Neutral is only needed if you want to get 110VAC from the 220VAC, which isn't necessary in this application.
There was one thing with the locking pin where some plugs can sense the opposite, I am paraphrasing but wonder if this could be related to a locking pin sensor, detecting whether the pin is fully attached or not.
Great video!!! The conceptualization and scripting was spot on, and not every one understands the work that goes into production, editing and ULing these videos for commenters to criticize your every waking move, after all you are just someone that builds EVs for a living, integrating not necessarily meant to talk to one another parts into some homogenous friendly group that plays well together and tell you that the can bus is not a Token Ring or that the can bus needs ending resistors that are actually at the ends....
Thanks for the comment!
You and Zach are my 2 favorite channels. This was an awesome video. Well done.
Wow, thanks!
The influence of JerryRigEverything is just amazing
Yes it is!
So excited for this video.
Check Unified Diagnostic Services (UDS) using CAN. Use CANalyser and CANape for Diag. It will provide you the error codes and possible fault(s). I do that all the time with most of the Electronic Control Units (ECUs) of a car. Diagnostic and Communication via CAN, CAN-FD or LIN or any of those expensive comms(MOST, Flex Ray and Ethernet) is a headache. I always follow the boot sequence, diag session (Default session), then check for Read Diagnostic Trouble Code (DTC). Check the response code for Read DTC.
Thanks! I'll check it out
I'm so interested in the electric hummer working and I can only support you guys with prayers cos I have no clue what you need to do to make it happen. Good luck and best wishes guys. I'll be watching with keen interest and by the way Happy New Year 🙂. Subscribed 👍
Welcome aboard!
Yes I drove a 1972 Dodge Challenger for 15 yrs and it didn't catch fire 🔥 because the wiring was done perfect! An as far as I know I got the most miles out of dodge Chrysler challenger! An everyone else didn't drive the car or it Burned! Which is kind of cool I think that I've started thinking I should convert it into a EV called the radio station and discussed on air with the NPR PBS host who was super nice and added she'd love to drive in one of those!
As others have commented already I would try components in isolation. I have had issues in the past with message IDs clashing, checking the broadcast message IDs from each component individually would help identify any clashes. You mentioned checking continuity, but have you confirmed the BMS is waking using the output from the charger?
Thanks for the comment!
Thanks for the quick update. Also looking forward to seeing the project completed.
You and me both!
Keep up the good work. Came because of Zach's car, will stay because of the cool content.
Awesome! Welcome aboard!
So excited for this series
Well,- Then, why don't you send a "Super thanks"??
Welcome aboard!
My suggestions:
#1 Check the grounds. Seems so many vehicle electrical problems caused by bad grounding.
#2 Put an analyser on the CAN bus and see what the charger is sending. The fault code should indicate what the problem is.
Given Jerry’s previous comments about inability to see metrics on the display, I would suspect the CAN bus connections / configuration.
Thanks for the comment!
Here’s my tip: don’t put your finger where you wouldn’t put your dinger!
Been following Jerry form years
Now and I loved his hummer project hope it will be fixed
Yes it's out
Thanks for putting a video out! After hearing that Zach was bringing it to you I was eager to watch. Glad you got a light on lol
Thanks for watching!
There's something off with the audio.
Cam u please combine stereo to mono wherever possible because the left channel has way too much volume than the right. Headphone experience isn't good
Got it!
Very interesting. I did a pin out to heavy duty fan on my Hemi
Nice to see your expertise being put to good use...
I'm convinced that electrons have a mind of their own...
OMG! You are so right!
Thanks very much for your care and interest in the whisper project!
Any time!
New to the channel followed watching the whisper project. It's a really interesting channel. keep up the hard work. I look forward to seeing some more awesome builds
Welcome aboard!
Connect a oscilloscope to the Can Bus and look if data packets are being sent over the network. Look at bias voltages as Can Low should be at 2.5v nominal and pulled down to 1.5v and Can High should be at 2.5v nominal and pulled up to 3.5v. If your voltages are lower it usually means a bad power feed to a module that communicates on the Can Bus and if you have elevated voltages there is a module with a bad ground that communicates on the Can Bus. That is the only way to truly troubleshoot a Can Bus system. A multi meter leaves to many variables when testing Can Bus as you need to see the data packets. Make sure the waveform has good square waves with a higher square wave at the end of every message. Make sure the wave forms are not leaning into a direction but pull straight up and straight down. Hope this helps
Thanks for the comment!
Great synergy! Keep it up.
Thanks, will do!
New subscriber here; I like your generous and genuine approach to solution finding. Nice catch on the polarity of the branch circuit.
Thanks for the sub!
nice.
Thank you! Cheers!
First soldering I've seen on youtube in the last few months that looks like you gave a damn about what you were doing. Brought me good brain juice.
Thanks for the comment!
Is it just me or is his voice only coming through the left speaker?
I'll have to check it out
When you record on an Iphone you can change the audio to be mono in the camera app, so the sound will come out of both speakers when played back.
Thanks for the suggestion!
Your video production is pretty good although I think the biggest room for improvement is microphones.
A good mic could dramatically improve your video. I'm not confident enough to give a recommendation, but there are tons of resources online to get recommendation at any budget.
Thanks for the comment!
@ElectricSuperCar I suggest a lavalier mic since the audience can hear you no matter were your camera is pointed
I have now a new member in my favourite RUclipsr’s list , Thanks Zack!
Thanks Friend!
You may have to charge each cell individually then try again. All it takes is one cell reading under 2.7v and it wont function.
I'll have to get a CAN adapter and talk with the BMS, see if something like that is going on
One row*. The all the cells in parallel would have the same voltage
@@NvidiaRTX5080 Ya thats true for some reason i assumed it would be wired in 4.2v but that would not make sense for any electric motor. It may just be 1 cell that is faulty and you will not know unless you tested every cell individually or if the computer was smart enough to display a error with a pack of cells then your stuck checking every one yourself. Because it took him so long to make the hummer chances are the batteries got really low and is causing these issues. Its the most common problem with lithium batteries and its the same reason why samsung phones are popping open because of the batteries inflating. Charge your batteries! 3.7v for long term storage.
Excellent plug on the acoustic treatment.
👍
Not only is it the echo, but it’s also how much bass your audio has. Even losing my bass, it was still too much
Yeah, some better mic would be a good thing
Loving the mono to stereo jumping ❤
Sorry
I hope jerry completes this build I can’t wait for it
First video that I’ve watched! Love the technical aspects! You got a new subscriber!
Welcome aboard!
Coming in from JRE for the Hummer Project :) Lets get started!
Welcome aboard
I just love how much your videos have improved since the beginning
Thanks Friend!
I actually saw this when Zack announced it, and had already given it a thumbs up, but sadly didn't follow it up with the rest of the videos. I will immediately remedy that now, lol.
Great video! Listening on headphones, the first 3 minutes your right channel sometimes sounds like you're underwater, it's only the low frequencies, while the left channel sounds fine. Maybe you didn't notice before, maybe it's a known issue, just thought I'd let you know :)
thanks! sorry about that
im too invested in the whisper project, it was the only thing i looked forward to watching back in 2022. hope she runs, good luck Doc
Thanks Friend!
Want more videos on the progress, have been following Jerry Rig this entire time...!!
Really excited for the fix and completion of the Hummer✌🏻
More to come!
Thats a huge inprovements as i have been following this project from the day it started and i am really enjoying and learning a lot of things here keep up the good work definitely waiting for a new video
Great to hear!
I have been intrigued in doing EV conversion, and JerryRigEverything have been delivering every nuance of the conversion job on his converted military Humvee. I will be watching the incoming videos to see how you can fix the Humvee and get it back on road.
Thanks for the comment!
Subscribed for the hummer work, but excited to stay for other videos in the future!
Welcome aboard!
That is the best intro I have ever seen! I love it!
Thanks Friend!
I don't know much on electric cars, in my country Tanzania there might be few or non, but I love this project. I'm excited on the next update 👍
Very cool!
You could build a short extension cable for your can bus connections then sniff the traffic. You can sniff with a scope. I also recall that if you have access to the individual wires you can use a clamp on sniffer. Of course your can topology is important, but I recall the owner already me noted that.
The felt made a nice difference to the reverb in the room but I'd add some square block corner foams - that'll cut down but still leave enough to enjoy music
Thanks for the suggestion!
Subscribed! Love to see these updates on the Humvee project!!
Welcome aboard!
Finally all caught up in the whisper project videos. Nice job tackling the HUMVEE. I think in the next video we will see it driving out of your garage.
Fingers crossed!
My Saturday morning treat.
Hope you enjoyed it!
I know that I'm late to this party.
Anyway, in the industrial applications where we had communication issues, I would rent an oscilloscope that has a CAN decode function and analyze the packets in order to narrow the issues down (to a device or a configuration issue). Don't know if that is an option for you. There's also some good CAN to USB converter and analysis software out there. It's just that the Scope served multiple purposes, for my use case. Good Luck!
Thanks for the suggestion!
