Ok my brick has been parked for over a year because I cannot figure out why its not charging anymore. Backstory.... I had my speedometer rebuilt twice and the tac was fixed about two years ago. I replaced the alternator also. I replaced the larger cluster lights with LED's. I also just got a new/ used cluster and plugged it in on 05/19/16 and no luck.

When I turn my Volvo on the idiot lights turn on a faint amount. I know when it does this the battery is not charging. I go under the hood with the car running and remove the small red wire to alternator and plug it back in when the car is running, The idiot lights go away sometimes but if not I need to bring an outside 12 volt source( direct wire from the positive side of the battery) and the car charges without any problems.

I believe the issue is somewhere in line with the " exciter wire ". I don't know how to trace the exciter wire because it is wrapped up with all the other wires.

any help would be great. I really do not want to junk the car because of this issue. My family has owned the car since December 9th of 1990. I love my brick and want to get it running again.
