But, first he said A1 A2 and A3 .5 ohms and NOT grounded to frame. And 13.6V at idle. Then after battery died and tried to charge, was 13.2 at 3K. Still charging, but shot battery drawing high load from regulator, and not charging. 13.2V is still getting something from stator. I'd try a new battery first, or disconnect battery from system and see what voltage is at output of regulator?
