to test the alternator, do I have the car running or off?





Alternator test, engine running, 14 to 14.5 volts.

Battery test, engine off, headlights on for one minute, 12 to 12.5 volts.

Edit.
Just noticed this. "I just had my alternator rebuilt about three weeks ago". What do you mean by rebuilt? New brushes, new regulator? or a rebuilt alternator from the store. And what brand?
