how as the alternator checked?? what voltage was present at idle and at 2500 rpm??

12.59 @ both. it stays around there until i use a/c then slowly drops
not enough. it should be 14 to 14.5 volts. my opinion is you need an alternator.

This is the 2nd one I've put on and the car still does the same as it did with the original. Could something be knocking them out as I put them in?
Many customers brought in Autozone alternators to my Napa store in San Francisco and once we tested it on our Alternator test machine they left with a Napa alternator
Thats where I'm headed then. thank you
always use mitsubishi parts and keep it tuned up
