1991 Mercedes Benz 300sl 6 cyl Two Wheel Drive Automatic
Battery goes down after sitting for 2 days. 12 volts on ground lead when disconnected from the battery. Car alarm starts going off when battery is low. I have replaced the voltage regulator on the alternator once. The battery does not go down if you disconnect the ground lead. How do I determine what is draining my battery without pulling every fuse one at a time?
