For anyone else reading this in the future, the problem was at the engine side of the firewall harness/plug. This schematic pin out number on my 74 is 18, but it was clearly fried once I pulled it off and looked at it.
I bypassed it ( cut the wire on the back side of the harness) and fussed it...
Thx.
Check out the picture closer when you get a chance. That wire is pretty thick and comes from the alternator is my understanding. (Through the firewall). Although my amp meter is bypassed, I agree, I think Ill move that fuse to u under the hood.
The idea was extra protection that wasn't...
I have a alternator that is putting out about 30V (at the alternator B), and a battery that's not getting charged, which is probably a good thing since the voltage is so high.
A little history, I think the original problem was the positive at the alternator was grounded to the alternator...
