Take that alternator to autozone bud, on or off of the vehicle they can test the alternator and tell you if it's shot or not

Oh ha, sorry man, didn't really look! Any parts store near you that would have a machine to test the alternator and regulator? I mentioned Autozone cause I work there part time

I found a blog forum on the issue, said the following :

What do you guys think? Voltage Regulator

  • Nearly every automobile alternator-generator unit is coupled with a voltage regulator, which determines the actual output of the alternator. The voltage regulator detects the charge level of the battery and can decrease the voltage output of the alternator once the battery is nearing full capacity. As a result, the voltage output from the alternator, as it produces electricity for the vehicle's battery, may drop once it has reached higher RPMs if the electrical load requirement is low.

Well... That's ehow... LOL

That might only be true if your alts is PCM controlled. But it shouldn't drop into battery voltage when revved.
