Battery drains when not running
Battery drains when not running unless I
disconnect it, then it's fine.
You have an electrical draw on your charging system somewhere. Sounds like your ALTERNATOR isn't keeping your system charged buy a multimeter and check your voltage with car running and accessories on should be between 12-14 volts if not your ALTERNATOR is most likely the issue. Good luck
Probably a "leaky diode" in the alternator is draining the battery. Test that first by disconnecting the alternator to see if the problem stops.
