Hot negative battery post and no power

ok, had shop install new cable. hopefully that was the problem. i have noticed something tho. i seldom pay much attention to the battery gauge, i have never thought they were accurate or useful,just something taking up space. but, before cable replacement it always read over the 14volt mark witch is at 12oclock. now it shows what i assume are normal fluctuations like it will be at 14volts or higher when its warming up and goes down slightly below 14volts while driving.
i sure hope the problem is fixed!

if the problem persist's let us know so we can share whatever information is found with others, good luck!

The wire is not making contact in the terminal needs resoldering. another problem was the original batteries had inside them connecting straps that were not conected properly, defective welds. Remedy is new battery

If your negative cable is hot when dead, your ground isnt working properly and is creating a crazy resistance.

A friend of mine was helping me get my turbo Silverado ready one spring. The battery was toast so he threw in a new one, but hopped onto helping me with something else before finished, and left the negative half loose.

We fired it up, went for a rip, made it a block and all my gauges started bouncing. Started heading back and when I pulled up the driveway, smoke was pouring out from under the hood. We grabbed the extinguisher, and popped the hood. The wire harness was burning like one of those little kid firework snake coils you light the end of.
It burned all the little individual ground wires in my harness.
I wouldn't even risk it if it's getting hot.

update! replace negative harness with ac 2284641 for perfect fit. i just took a weekend trip 6 hrs away and no issues!
