Mercedes R230 SL55 consumer battery drain - FIX

If the battery in your car runs down after just a few days, the chances are something is draining the battery. This video shows how to determine whether you have a battery draw and how to quickly locate the source of the problem.
Often people will try and diagnose a battery drain by removing fuses, but not all battery draws are on a fused circuit. Similarly, it’s difficult to ascertain the level of your battery draw using a standard voltmeter on a car like a Mercedes R230, because the voltage and current spikes are likely to blow the fuse in your voltmeter.
