Wrong pulley would cause the alternator to overspin, and the regulator to be operating way too much. Could be excess water entering the electronics... could be even your belt slipping and you're just misdiagnosing... dunno... what makes you think the voltage regulator has gone south?

Heat. It's an electronic gizmo and heat is the enemy. Buy a "lifetime" warrenty part and just resign yourself to chainging them out every so often.

Maybe if you've jumpered the car off, a diode in the alt has gone.
Or how about this. See what the alternator is really putting out. Put your meters pos lead on the alternators out put. Right on the nut that holds the wire down. Right there on the alternator itself. Neg on the battery neg post. Is there a signifficant difference b/t that voltage from putting the meter on the batterys positive post and meters neg on the battery neg????? If so, I'd suspect a bad connection at the battery cables.

Oh yes. When you put the key to ON, do the idiot lights all light up as they are supposed to???
Do you have the two small wires connected to the alternator?? Original plug?
