Belt is new and tight. Electrical systems aren't that high up on my competency list so over explaining that stuff would help me out. So I've got 12.58 constant voltage at the battery. That is with it sitting, idling, everything on/ held at higher rpm. It never changes more than .01 up or down. With key on and on while running I have nothing at the aux post. The only part of the alternator showing any voltage is the output post which matches battery voltage. Readings at the starter while running are 0 at the start terminal, 10.6 at the ignition, and large post matching battery voltage at all times.
