MIKE-2U Posted April 23, 2012 Report Share Posted April 23, 2012 Ok so this problem has been occuring now and i am clueless. My volt meter is hooked to my amp and calibrated with a ddm so its accurate. After my alt warms up my amp will read like 12.9 volts and some times after i hold rpms for 10+ minutes it will climb back up. Now when the amp is reading 12.9 car running , the battery will read like 14.2 !!? Im lost first i thought the alt was burnt.

Trey_Dog650 Posted April 24, 2012 Report Share Posted April 24, 2012 your question is a little confusing, but maybe your losing 2 volts through your wire...

FeArZ Posted April 24, 2012 Report Share Posted April 24, 2012 I know your car being a GM your alt is PCM controlled so it will charge around 12.9 while driving sometimes. Now why it's reading 14v at the batt and 12v in the back is unknown to me.

LUV bass Posted April 24, 2012 Report Share Posted April 24, 2012 Yeah, check the fuses, and maybe try popping in a new one. They can get partially burnt out, but still look ok.
