Well I got my parts in the mail from Classic Industries today. I got a whole weekend to chase sparks & arcs, and try to resolve this problem.
The Regulator is a Delco part and I hope that this is the end game (sounding like a broken record).
When poking around I noticed that there is a solenoid on the driver’s side firewall which is down low near the starter. This is an afterthought from some previous owner kluge? It looks like that I am going to rewire my whole starting and charging circuit before I get to move on to other fun challenges.
Also I found that there is an extra red wire from the horn relay to the firewall, I plan to find out where that goes. Maybe the drop-top motor, A/C or power windows? Looks like a factory install.
I just finished a complete 4 wheel disk brake with e-brake install (complete with shedding the last of my gray hair). Had the TH-400 rebuilt. Rebuilt the rear end. Now the electrical. Fun Fun and more Fun.
Results to follow………… (pending a free Weekend Kitchen Pass).
