Just read your post; sick truck bro. My dad and I install/wire street rods and customs on the side. If you decide to go aftermarket wiring, use EZWIRE. All wires are labled, colored and seperated. On Gm alternator is it a single wire? If it is some will not charge until it reaches a certain rpm. Your drain could be main power/ground is corroded on the inside. Feel how flexible it is. If it's stiff, no good. You could also ohm it out and check resist5.
