Please help Me.."Overcharging"?

I haven't read the complete thread, but is the regulator you got from Advance a BWD brand? Is it painted with a grey epoxie paint? BWD had a whole batch of bad regulators on the shelf of many different Advance stores. All the ones I ran into would not charge due to the case not being grounded internally. It is not out of the realm of possibility that they might have some bad ones that over charge.
