Tahoe/Yukon/sierra/Silverado ground issue, no start, or electrical issues fix

I was having issues with my Tahoe not starting and it was turning off while I was driving and all the lights/locks would go crazy. I looked it up online and most people said that it was a ground issue or the battery cables. I tried cleaning the grounds but that didn’t fix the issue. So I changed the 175 amp and the negative battery cable. I drove almost 300 miles this weekend and no issues so I think that fixed my problem!

If the interior ever goes dead, follow the parking brake release cable and you may find it leaning against a black box in a galvanized bracket. Move the cable away and everything will work again.

Hey all, I have a 14 Tahoe that was having a similar issue. Occasional no start and turned into no power in the truck at all. Completely dead. Turned out to be the main power connection into the underhood fuse box. It's basically a large spade terminal that overtime loosened up and add to that a little corrosion caused major head aches. Search how to split the fuse box and once it's open you can't miss the connection. A little sandpaper and pinch the female side a little tighter with a pair of pliers. That's what worked for me.

Thanks Mike. I'm going to try replacing my Neg. cable. Yesterday, it died on me as I was turning a corner. No interior lights, NOTHING ! It was like there was no battery in the truck. (2014 Silverado). Jiggled the neg. cable, then all of a sudden, full power. Never seen anything like this. Could have been a very dangerous situation on the intestate, no 4 ways, brake light etc. ! Not the first time this has left me "stranded". BTW, BEAUTIFUL Impala in your driveway, CLEAN !!!

Hey big bro thanks just know there is another ground on the other side near the fuse box by the fire wall that gives ground to you relays. I just changed my bcm they are notorious on these SUV’s for going out had to have it replaced and reprogrammed. One more for you look by your passenger tire where the door is and find your ac line that drips water ok and there will be a Coolant line that runs to the back you will see a strap that holds wires in place remove the metal strap it will make a small hole on the coolant line and it will make you think it’s you ac dripping and you will wonder why you truck is overheating just trying to help like you help others stay blessed thanks🙏

I am in the middle of the same exact problem. 2007 yukon denali. Personally, I don't believe it was the ground wire that fixed your problem. But rather the sensor that's attached to it. Battery current sensor. I will update this Comment later this evening once I finish and get home.

Thanks for doing this video. My 09 Tahoe failed to start twice now. But both times after a couple tries it fired up. I will be changing out the cable.

Good video man my 2007 Silverado is doing the same thing. When I touch the negative battery cable it’s actually hot so I definitely think it’s the problem.

[bigdaddymccoy]

Great Video. My 2011 Tahoe is doing strange things also. Turn the lights on bright at night makes the DVD player turn off. I changed battery and alternator. I will look at this now!!! Thanks.

Thank U for this Blessing bud, I believe this is whats going on with my truck as well since its doing the exact same thing. Will clean it up for now to get it started and go buy a new oem ground wire setup and then comeback and repost or update my comment to let you know how it went... Thanks again for this video...

General motors has discontinued this part. Not sure why. All that's available is aftermarket cables.

[emechanized]

Thanks for posting, my son’s truck has the same issue. I’m going to give this a try and I let you know how it goes.

..nice job, never knew that mega fuse even existed.

[Lynchie]

Our 2020 Tahoe had this happen today. Going to try your suggestions and see if it works. Pulled in, parked and 5 minutes later leaving completely dead nothing.
