Regulator gone bad?

Hmmmm, been charging the battery at 2 amps for the last 48 hours and haven't seen any change in behavior. Spins the starter like crazy but the voltmeter in the run position shows only 10 volts.

I'd be double--checking that voltmeter with a test meter right at the battery

Hell, even if the alternator is not charging at all, after starting the car, it should run at about 12, more or less, for awhile.

10V is a dead battery. 10V is less than I'd expect to see for CRANKING voltage.
