Have a 1995 buick park avenue with 3800 series II motor. Rebuilt the motor and put back in, car runs, but alternator is not charging. Had the alternator tested and was fine. Brand new battery. It will charge if I run a jumper from the positive on the battery to the plug in on the back side of the battery (only one wire). As soon as I unhook it it stops.I have.04 volts on the wire that goes to the plug in. All fuses tested and replaced. What could cause it? Wiring all looks good as well
have the same problem?
