We’ll if it’s a matter of that, maybe the rectifier diode is shorted on the alternator and has a direct path from the battery to ground.
Alternator was in the shop today and tested.
All diodes are good.
Low voltage 13.70 Actual voltage 14.68 high voltage 15.7
So the alt is good, it’d just a question of getting the reg set right because it doesn’t surprise me that it’s acting a little quirky after all the stuff I’ve replaced.
