Gets hot and stalls out

I’m with you- I don’t think it’s a direct engine heat issue anymore either. I’m going to look at the wires on the alt again. The ground post on the alt is very close to the block if I remember correctly; I thought that when I installed it. I’ll check those more closely.

So pour a little fuel down it’s throat and see if it fires off.

Nothing about the alternator is going to keep it from running except a dead short, and you would know it if that was the case.

You would have an electrical fire.
