Electrical problem - hot positive wire

[dazman242]

I recently bought an 02 Z71 with 120K on it.

The problem that I have is that at idle, it seems to stumble every few seconds or so and when it does I notice the oil gauge fluctuates too. This wasn't an important issue until yesterday when I was driving. After about 1 hour of mostly interstate driving I was turning a corner on a back road and the car just died. I coasted into a gas station and after about 30 seconds I tried to start the car and it started fine no issues. I drove back another hour to my house with no issues. I took it to the local auto parts store and they did the diagnostic of the battery, alternator and starter and all turned out fine. The only thing we noticed was that the positive terminal cable was too hot to touch. So today I went out to the truck turned on the car and went and felt the cable again. After just seconds the cable was too hot to touch. Anybody have ideas on what to check?

i remember from playing with lion L toy trains that on a transformer, the wires would get hot and sometimes smoke, if there was


1. a short
2. wired backwards
3. whires rubbing/touching

so that may be happoning with your battery cables.


FWIW/HTH

I'm thinking it's a short but where? None that are obvious to me. Maybe an electronic component that is know to cause this issue maybe?

if its a short, its gunna be somthing that usally starts up as soon as the truck is running, since you staited that with in 1 min the wire was hot , so lets list those


what features do you have.

autoride- do you have auto ride, they wrote it below where the LT badge is, does it gurgle from the rear end, becasue that turns on on my yukon about 5 seconds after its running.

stabilitrak- that does a self check when you start up.

fuel pump- possable because it dies on you.

ac/heat radio- do they all work right

does it start easily?

i will keep brain storming but someone else will come along here preety soon with their 2 cents :thumbsup:
