- In this video I explain what a chassis ground is and why it is important to maintain them in your Corvette. Then I show you what the process looks like on my C5 Corvette. At the same time I install a new battery and quick connect for the battery maintainer.
Excellent video. I appreciate the detailed classroom explanation. I will be cleaning up my grounding points on my 2002 C5 this winter. I have some gremlins creeping around.
Thank you for the kind words. I hope it helps you out.
you are the BEST ! you explain everything with great detail, i need much help with my classic 1987 c-4, and will be looking for your vids ! thank you so much !
Please hit me up if I can help you out in any way. Cheers.
Wonderful, plain simple explanations. Great video
Thank you.
Thanks for taking the time to do this video. I’m pretty sure this is the root of some issues I’m seeing with my C6.
Thanks for the comment, I hope it helps.
How can that be? To my understanding, the C6 version eliminated this problem by soldering the ground connectors to the chassis.
Excellent video. Very informative to help sort out electrical gremlins on the C5.
Thanks for watching! Hoping to get some more videos up soon.
Thank You Mr. G from Las Vegas! Appreciate y
You, Your an inspiration in the Corvette Circle!
Mike, Thank you very much for the kind words.
Back when aluminum wire was the "thing" especially in residential wiring, we used an antioxidant called Noalox an Ideal product.
This stuff was really good if slathered on anywhere copper and aluminum touched.
It was required for installation of the service entrance. I believe it was some type of graphite grease.
Anyway thought that might help......
Terry.
Where do you find noalox?
Great video. Thanks for the explanation. A new subscriber.
Good video. Thanks for the info!
1999 Corvette, I have watched other CZcams video about how to remove and repair the EBCM on their vehicle but mine has a different EBCM, Thanks, Skip
Skip, You are correct. A different module was used from 1997 - 2000 and is not repairable they say. I am still trying to get someone to donate one to me so that I can examine it myself to see if there is a way. No luck getting one yet. Working ones are hard to come by for those years. You might want to call Brandon at ABSfixer.com and get his opinion on your options.
Skip, If you find a replacement and would like to donate you old one, I will take it. I have been trying to find a broken one to examine. I want to see for myself why they can't be repaired.
@@justcorvettecrazy116 have you heard of any repairs ? Since ? For 97-00
Thanks I learned a lot I appreciate that
Cool!
Great video, thanks !
Thanks for the nice comment. Spread the word.
I heard that the C6 version resolve this issue by soldering the ground connectors to the chassis. So, why not just solder the ground connected to the chassis on the C5?
The base model C5 has a steel frame?
Great video, thanks I learned a lot!
Thanks for the nice comment.
Great video... I've noticed you didn't replace the Optimum battery with another one... Just wondering why ?
Thanks...
Thanks for the comment. That was the second Optimum Battery I have had in that car. Thought they were dying a little premature so I thought I would give something else a try. Was only 1/2 the cost as well.
@@justcorvettecrazy116 I just subscribed to your channel... &
Thanks for the answer...
C6 related: I took a 2005 Corvette (base car steel frame) and installed the stock battery cables from a 2006 Z06 (aluminum frame) to relocated the battery to the trunk. I wonder if my ground is insufficient since the base frame (steel) conducts electricity more poorly than a Z06 frame (aluminum) I may remove the Z06 battery cable which is battery to frame, and make my own cable (1/0) from battery to cylinder head. I've had a weird service electrical system message in the DIC for a while, no other symptoms or issues.
The difference in the resistance of the metals is so small it should not make any electrical difference. What you want to watch is the actual connection points. Different types of metals sometimes form oxidation at the connection points. We saw this back in the 70's when houses switched to aluminum wiring but kept copper plugs and switches. You can use an anti-oxidation paste to solve any issues if you are worried.
My c5 corvette rear wheel speed sensor is bad or needs cleaned according to my c1234 code and not being able to reset it. I did resoldered the 5 internal relay posts in the EBCM module. I haven't takin the wheel off yet because I'm getting mixed ideas on what actually needs changed (NOT FROM YOU). So after the wheel is off etc is it just a matter of taking off a bolt and pulling out a kinda bullet sensor in that hub area or is it factoried into the hub itself. Which I would have to replace the hub assembly. The hub assembly is like $130 and I found a ACdelco #213-344 speed sensor on Amazon for $31 dollars. What do you think?
Thanks for reaching out. I have not had to do a wheel sensor on a C5 yet. But did some quick checking and it looks like the rear hub comes with sensor and is not a separate part. I do not have access to my C5 today to verify this. Even when I look at Rockauto, there does not seem to be a listing for rear ABS sensor by itself. have a look at the pics on Rockauto and there is a plastic ring pressed onto the hub. Not a bolt system like other abs systems.
I snapped off the ground post on driver side front. Right next to the windshield wash basin. I cant get to it easily, should i drill it out and put a new post in or just drill and tap a new hole and put a stainless bolt in.
Either option should work fine. Which ever option you choose just make sure that the connection is clean before you reconnect the ground. If you go with the treaded bold don't thread lock as is could mess with the quality of ground connection.
My name James, I have a 2000 corvette convertible with 63 thousand miles on it. Every now and then all my warning lights come on and every fail message displays. The only thing that stops working is my AC, otherwise all else is good and the car runs great. If I shut the ignition off and restart the car everything goes back to normal and might not happen again for the rest of the day. Can this be a ground issue. Today I’d 8/05/2024 at 11 am eastern standard time. Thank you.
Hey James, C5 Vettes are very voltage sensitive. So any drop in voltage can throw all kinds of false errors. First make sure your battery is good and strong. Then look at the grounds. Focus on the main system ground and the ground for your dash display.
@@justcorvettecrazy116 thanks for your reply
nice job
Thanks for video. It would have help me a lot if I could see what you was doing.
Sorry, I tried to do the best I can. If you have any question please feel free to ask.
I wanted to see how to do what you did no disrespect you actually did it and I want to do it too.
@@aunttriciaattic Which part Vivian? Maybe I can recreate it.
Do you have a social media or a way I can reach out? I'm really scratching my head on my service charging system issue. I've done what I think is all grounds new alternator new starter solenoid and battery is good and I still get the fault. Can't figure it out? About to do the BIG 3 this Monday when kit arrives if that doesn't work I'm clueless
You can reach out at: justcorvettecrazy@gmail.com
thanks so much, great details. I'm having a problem with a battery drain on a c4, I think it hs something to do with the flashing security light? Any suggestions?
How long does it take to die? Any modern car with digital radio and alarm uses up battery over time. The key is to find out how much time and is it too quick.
@@justcorvettecrazy116 I have the original stock radio in the car and it doesn't work, If I keep the battery hooked up overnight, its dead in the morning. When I lock the car, I see that security light flashing. I was thinking it had something to do with that.
The guys at the local shop said my alternator was not strong enough, so they replaced it with something stronger, but that didn't work as well.
Charge up the battery...Pull out the fuse for the radio and the security system and leave the car and see if the battery still dies. I wonder if there is something in the radio systerm draining it since it is not working. Maybe the audio amps are not shutting down?
@@justcorvettecrazy116 Do you have a facebook page, I'd like to send you a photo.

I have a 2016 3lt Z51 I've had a electrical gremlin in this car since it was new the temperature gauge will stop working canceling the rev match air-conditioning I've replaced the temperature sensor twice has been to the chevrolet dealers I get charged even though it's under warranty because they can't find the problem it kicks the cooling fan on full speed stays on after the car is shut off the car has never has overheated so what up
That is an interesting one...Have you looked at the PCM? (If it cancels out the rev match) please shoot me an update if you find the issue.
Nice video.but I have a c4.91 convertible to be exact.are the ground locations in the same place?
I am sorry I have not had the chance to map out the grounds on the C4.
Great video, learned a few things that will come in handy. I'm having an issue with my '90 C4 convertible that seems to be a ground issue but I can't locate the cause yet. After driving for a few minutes the speedometer flashes garbled data, the inside lights blink on and off and then the speedometer goes out. Sometimes if I let it sit it will restart, other times the inside lights/map lights don't work and it won't start. I replaced the ECM, it feeds the speedometer and controls the VATS, with no change. Any thoughts?
Yes that could be a grounding issue. Do you notice anything else going weird at the same time or is it all inside the car? Do the headlights dim or tail lights? Does the stereo go out? If you make note of all the things that go weird at that time it might lead you to a single ground/power issue.
@@justcorvettecrazy116 The lights are not effected, the stereo and HVAC still work. It appears anything impacted is off of G201 though not everything connected to G201 is impacted.
My 91 does something similar.but only when I'm gassing it going down the road.dash flashes, engine stumbles, and check engine and service abs lites flash.let off and it straightens out.
@@randisellingham2551 Could be ground issue but also an alternator problem.
@@randisellingham2551 I had a similar problem with my 95 but the asr light along with the engine light would come on.it ended up being the throttle position sensor
I have an issue with my C4 corvette when it get warm the electronics start to flicker like crazy headlights, rear lights, and the gauge cluster.
Yep, that sounds like a bad ground or a bad 12V line. Check the main battery terminal block located behind the battery on the C4. There are many grounds, unfortunately I do not have a diagram for you. What year is your car?
@@justcorvettecrazy116 it's a 1985
I found an image of the C4 grounding points. Shoot me an email and I will send it to you. justcorvettecrazy@gmail.com
@@justcorvettecrazy116 thank you
Would it be possible to show the ground locations on a C6 Z06 since it's battery is rear mounted.
I am going to assume that all grounds are the same except to the main battery grounding point. I will look to see if I have any info on the C6.
@@justcorvettecrazy116 I would appreciate that 👍
Hi, I watched your cleaning the ground connections and have cleaned the main ground and other that were easily visible. I am trying to correct a problem with my EBCM, I have looked at a number of video's on how to take it out and solder the 5 points but my EBCM is a different style ABS-5-TCS/AH DELPHI DELCO ELECTRONICS SYSTEMS MODEL: 09360921. Are you familiar with this model, it has 4 bolts on the corners and a nut at the bottom middle, I can't get the front to separate from the back. Do you know how to get it out and if I can get it out I would be able to solder connections to get the unit to work or is there some other way to repair? Thank you for any help or suggestion, Skip Crane
What year is your car Skip?
Great video, I have cleaned my ground just like you did but I am still having trouble with my signals (they stop after they get hot) any suggestions?
Do all stop? Or is it front/rear? When they stop do you still have hazard flashers?
@@justcorvettecrazy116 all, and yes the hazzard too
@@user-zt3zq8uf1z That should not be a grounding issue as the front of the car and the rear of the car would use different grounds. Let me do some research and get back to you on this one.
@@justcorvettecrazy116 thank you, any help would be great!
This is driving me crazy
This is a solution:
www.2040-parts.com/c5-corvette-flasher-fix-signal-fix-led-flasher-bypass-harness-i756624/
All other fixes will not last. On my 2000 Corvette if I pushed the Hazard Flasher quickly the turn signals would work. Not the best fix.
Best of luck.
I have a c6 that does one single click when i try to start it. Replaced battery and starter still the same issue. Any ideas?
Thanks for reaching out, Need some details... year, auto or manual trans, do you have accessories like radio working normally?
@@justcorvettecrazy116 2010 auto. Ground broke off while driving. Replaced terminal on battery and haven’t gotten it to start sense
That a strange one! I wonder if it has to do with the anti theft kicking in? Do you get any lights on the dash? Does your key fob work to lock and unlock the doors correctly? Can you hook up a scanner and get a signal to it? Other quick thing is to check to make sure it is in park all the way. Wiggle the gear shift a few times and try.
@@justcorvettecrazy116 fob locks and unlocks the doors. I’ll try to get a scanner on it to read codes. And I believe it does go in park because car stops being able to be pushed. I’m hoping motor didn’t lock but it happened slowly to a light and car was running fine before it died from the ground being off.
Was it towed? Double check that the trans is locked in park because there is a switch that prevents the car from starting unless it is in park.
When you hear the click, is it coming from the solenoid at the starter?
Do all you accessories turn on normal like radio and windows...etc?
It's okay to spray the ground after finish with Lithium Grease ?
I think it should be ok to spray after you make the connections but lithium grease is thick and will collect a lot of dirt and junk over time.
@@justcorvettecrazy116 thank you 👍
bro DC currant runs out the negitive does its work and returns thru the positive. Oh yes it does.
Correct! Negative to positive flow, that is called electron current flow which is what really happens because the electrons are the things moving. But in most cases we use the more acceptable understanding called conventional current flow, positive to negative flow.
Do you happen to have the grounding locations for a C3? 1981
Let me see what I can find. I do have a C3 Manual kicking around in the shop.
@@justcorvettecrazy116 thank you. I appreciate it.
I do not have any dash lights so after watching this video I figure I should look there first. Very informative video. Thank you.
First check your fuses, then look at your dimmer switch as a possible issue causing not dash lights.
@@justcorvettecrazy116 I checked the fuse first and it was good. But an odd thing is that I was driving it today and the center lights came for the guages, the shifter, and the windshield wiper switch, but not for my speedometer, and tachometer.
so where is my coolant temp sensor ground on my 2008 c6
If you are having an issue with temp reading only it is more likely the sensor than a ground issue. This is because that ground would be shared with other things as well. What is the issue you are having?
@@justcorvettecrazy116was overheating before I change all of this EVERYTHING FROM COOLANT TEMP SENSOR &PIG TAIL CONNECTOR NEW RADIATOR NEW FAN NEW FAN CONTROL MODULE NEW WATER PUMP NEW THERMOSTAT NEW RESEVIOUR
AN MY DASH AND TEMPERATURE NEEDLE keep moving funny and
Is it just the temp gauge moving funny or are other things on the dash doing strange things as well?
Hi, I couldn't see what you was doing I'm not asking you to do the whole thing over maybe I need to put on my glasses oh watch it afro times because this car have got on my last nerve
Zee O6 it's an American car. It's the name. Would you call someone named Zach, Zedach? Or Zain Zedain? No.
LOL Car might be born in USA but has Canadian papers, therefore Canadian
@@justcorvettecrazy116 Zee is still it's proper name. If I tell someone my name and it's different in their language I still expect them to call me by my name.
Had this issue and I thought it was the battery or alternator.
Everything ok now?
@@justcorvettecrazy116 Yes. No more flickering lights inside or outside. I think that was the reason my LED tail light would malfunction only on one side. Replace the led light 3 times. No it's been 8 months and everything works great. My C5 is daily driver.
