Alt. guage discharging all the time???

I had a 65 Valiant (one of my many) that must have come from the factory screwed up. Ammeter was reversed? when charging it would show discharge and vise versa. after many days of trying to figure it out i learned to live with it. Never had charging problem but was weird when seeing the gauge read discharge all the time. I'm sure this is not your problem but just saying. Somebody at chrysler must have been having a bad day that day
