Re: Charging too much, not regulator

It would really help to know year, model and other specifics about the type of charging system but that's a classic symptom of a grounded field coil within the generator. Grounding the field simply tells the generator to ignore the regulator and put out its maximum capacity. If you've eliminated everything else, install (and don't forget to polarize) a spare generator if you have one; otherwise it's a trip to your local generator/starter shop.

Any chance you freshened the cosmetics of the generator and installed a new metal tag? I've occasionally seen folks do this and mistakenly use too long a rivet and it drives into the field coil and grounds it.
