belt was tightened 2 months ago when I had to replace water pump. bearings were out and making some hellacious noise.

If the voltage regulator is bad can that be replaced by itself? Or does it require a whole new alternator? I'll check the battery this afternoon when I get back from work like you said. Time to break that new multimeter out of the box ;-)

The regulator can be replaced separately. There is a thread on here where I show the disassembly process and the part number for the regulator.
