65 Valiant charging system problems after repaint (Not a grounding issue)

I hope you saved the old parts. Most are better than new - unless / until they fail of course.
regardless.
IF everything is hooked up properly, then +20 to 30 amps shows either
a) the battery is not charged and is sucking as much as possible from the alternator
b) voltage regulation is high, probably over 15 Volts - causing overcharging. Here's where a voltmeter plus the ammeter is super helpful.


edit
+ means current is flowing to the battery. In other words, charging the battery.
