Deciding if the problem is a faulty alternator or a voltage regulator will require a bench test of the alternator.

Last night I had to move the car so I put the meter on the windshield and revved it up 1k, 3k, 4k... doesn't matter 12.xx V
I heard pepboys/autozone can't bench these alts. Is that true?

I recently did my heater core and removed the battery for access, all the cables are clean and appear to be in good shape.
I had to drive the car to work today (long story with backup car) and we're down to 11.9v running when I arrived.
