E500 Battery Drain
My 2003 E500 has a battery drain which I believe is 2.5 volts. Any ideas as to what the cause of the drain might be and how to detect what the cause is?

Place an amp meter between battery Pos and the battery cable, with doors closed and key out read the amps, if above say 1.5 (this will allow for clock, stereo and any ECU memory) start pulling fuses one at a time to isolate the draw, start here.mark (mhpautos)
