I have a 1999 540i with 120,500 miles on it. I discovered about two months ago my battery was dead one morning. I just changed the battery because it was the original battery. About a week later the new battery (a Sears Diehard, 850 CCA), was dead. I recharged it and started my long journey of electrical diagnostics. I discovered the electrical system of my car was pulling 2.20 amps when the car is off, after the battery has been disconnected overnight. The alternator is good, I have pulled every fuse, changed the ignition switch, changed the FSU (FSR), disconnected the amp and CD changer and something is still drawing 2.20 amps....can anyone help me, please?????
