What to do if your Chevy Tahoe battery is not working?

If the problem is not the battery itself I think you need to look at the alternator or starter motor. These two things are the only electrical parts in your car that could cause high enough amps at battery terminals to make temperature raise to a level that starts melting plastic.

Is there a problem with my Chevy Tahoe?

I’ve been having a problem lately with my 4DR 4WD Chevy Tahoe. Lately it has been completely losing electrical power while driving or sitting at a light. Everything is running fine, then it just shuts off. All lights, everything. When this first started happening, the truck would start right back up.

Why does my Chevy Tahoe have no spark?

There will be a big spark when you connect the last terminal if your car would be pulling that big amps that the plastic around battery terminal starts melting. You say that there is hardly no spark if any so at the time you connect the terminals the problem is not present if the problem is not internally in the battery.

What causes starter wire to burn on Chevy Tahoe?

Starter motor wire is very heavy duty and does not burn if grounded. Something else will burn instead, like battery itself. While driving a city street my ’97 4DR 4WD Tahoe suddenly lunged and all the dashboard needles deflected. As the needles settled down, the voltmeter showed a steady continuing drop.

Why does my Chevy Tahoe battery not charge?

New battery installed the engine jumped back to life but the voltage slowly dropped again to ~10V when a sudden high-pitched noise I’d never before heard kicked in and the voltage climbed back up. Since that time the battery does not charge in the vehicle though it charges fine on a charger. Was the sound I heard the last cry of the alternator?

Are there any electrical problems with my Chevy Tahoe?

Once I disconnected the battery, both positive and negetive the computers ECM/OCM seemed to “re-boot”. There have not been any problems since. I have a 97 Chevy Tahoe and after I run it for awhile it just shuts off, while i’m on the road. I check the fuse box and the fuel pump relay is hot.

What are the symptoms of a Chevy Tahoe battery dying?

Symptoms often are that without warning it just dies and then on the next moment everything seems to be ok. Then you say the battery terminal was hot enough to melt red plastic around it. If you draw that much power from the battery then it makes a huge spark when you re-connect the cable.

Why does my Chevy Tahoe not start up?

You could have an intermittent short at the starter motor solenoid, which would ground the positive starter motor wire and heat the battery terminal as the battery drains very fast. Starter motor wire is very heavy duty and does not burn if grounded. Something else will burn instead, like battery itself.
