ToNasty Posted July 26, 2015 Report Share Posted July 26, 2015 I'm pretty sure you have a 145 amp alt. So at idle it's probably like 80 amps ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

Kyblack76 Posted July 26, 2015 Report Share Posted July 26, 2015 Output is normally at 2k or so. And normally a cold rating. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Moreno93 Posted July 26, 2015 Report Share Posted July 26, 2015 You could have either, the more power options you have out of the max more likely you are to have a 160a, but you could have a 145a, thats at max output. At 500rpms your getting your idle amps, and at 1800rpms you should be getting your max, as far as figuring out what amp your alternator is either have to go to gm, or clamp it because it could be either or Link to comment Share on other sites More sharing options...
