do pay attention to what the ammeter is doing, and don't wire accessories onto the charging circuit.
Understanding Charging Systems with Ammeter

Thanks for the resource. I took a real quick glance, and I've put it on my reading list (with a star to denote importance. . . .sorry I'm a nerd.) Luckily I've never really seen any spikes on the ammeter, but that may just be BECAUSE this circuit is already fried. I'll make sure to keep an eye on it once I get this circuit back up and running

Side note, I also stumbled across this article, Improved Wiring for older Mopars, and it too looks like a good idea.

The biggest pain in the a** of this whole thing is waiting for the right wiring to come in the mail. I really want to stick with original colors so my wiring diagrams are still accurate. Radio shack used to be my go to for wiring and local auto stores only ever seem to have red and black.
