Readings right off the alt were:
Voltage - Varied from 14.5xV to 14.97V. Seems high to me, not sure what that would mess up, if anything.
Amperage - Went from almost 0A all the way to 40A really fast. So fast, I almost couldn't read what numbers it was showing.
Other than the alternator, obviously, being the main suspect, I have had something sqeaking forever. I think it's either the AC pulley bearing, OR my tensioner is too loose allowing the belt to slip on a pulley and squeak. If it is slipping on the alternator too, then that would cause problems I assume.
