So I've been fighting a parasitic drain since I bought the car(1981 B210.) I can't seem to find any evidence of a drain other then a dead battery in the morning. I've pulled all the fuses, disconnected all the lights, and I'm still getting a slight drain. Just enough to kill the battery by morning. Theres no evidence of any wires grounding, and I've gone over just about everything with a meter and found nothing. Any suggestions?
