Had a newly rebuilt alternator installed on my Bronco II a few years back. Would drain the battery when sitting at wife's place of work. What happened was that the voltage regulator although new, was defective. When wife would park car, go around to passenger side, open door to get her stuff out, the dome light would come on triggering the voltage regulator to switch on due to system (battery) voltage drop. Regulator would then allow field in alternator to be energized, even though the engine was off. This discharged battery over the day's shift, and no go at the end of her shift. Took some real detective work to figure that one out. Then, we replaced regulator with new out of stock, couple times, with new. And they were defective as well! Finally dug old one out of scrap box - put it back in, worked fine as long as we had the car.
