Hot positve cable on battery

I took the Camaro out today ( first run on new motor) and when I stopped by a buddy of mine I shut it off, and needless to say he wasnt home. So, when I went to start it wouldnt start, slow turn over, and when I went to check the battery cables I burnt my thumb on the positive cable.
What could be the cause of this?

Re: Hot positve cable on battery

The starter draws over 200A initially and then maybe around 100A. The more the starter turns, the higher the draw as the windings heat up. All that is going down that cable from your battery positive and the cable starts to act near about like a stove element. If you've got a stock style starter you may want to consider a PMGR one. They rely on gearing instead of brute force so they draw a good bit less and typically output more.

Also, it can mean a dirty/corroded junction between clamp and post.
Might be a good time to remove clamps and clean posts and clamps.

Yep, most likely dirty/loose/corroded connection.

Nope, not dirty or loose connection. Just put battery in.

What is the voltage on the battery with and without the car running?

Re: Hot positve cable on battery

How long were you cranking it before you touched the cable? Sounds like Steiner was right.

Re: Hot positve cable on battery

The size of the cable can make a big difference even if it is new and clean. What size battery cables are you using?

68 RS Coupe 355/350 TH, Detroit Speed, Hotchkis, Vintage Air, 8.5" 3.42 posi 10-bolt, MagnaFlow 2 1/2" exhaust, etc.
