I had the alternator tested and it showed it was not charging. I replaced the alternator with a re-man and took it back to be tested. Now it shows just barely in the charging zone on a load tester. Checking with a DMM showed 13.75V with nothing turned on. When I turn on the blower, lights and AC DMM shows 12.85 and slowly decreasing. Not sure if the alternator is charging properly. The car pulls 15 ma turned off. I don't think it is a loading problem when the car sits. Battery voltage after sitting 3 hours was 12.75 V. Is the alternator good?

Also does anyone have a schematic showing where the wiring harness goes that plugs onto the alternator? Should the engine idle higher when the AC is turned on?

easy wat to check if the altornator is working put a volt meter on the battery withe the car off you shoukd have 12v start the car and you should have 14v if not the altornator isnt working

yes the car does idle higher with the a/c on because of the extra stress.
