My Car Drains Battery Overnight by Provie(op):
Gurus in the house please help!

My 2005 ML350 drains battery overnight (occasionally thought). I suspected the radio/cassette player and did power it off through the power knob before turning off the ignition. The situation continued. But I noticed that the radio remains connected and running, because eacth time I power it On, the tracks and memory picks up exactly where it left off and all the settings remained the same.

Why I suspect the radio system is that same thing happened with my C220 two months ago, my electrician tried everything without success, even changing the diode of the alternator. I only learnt from him that if the battery end is giving out high sparks when the car is turned off, then something is ON and draining the battery.

Hence I made a habit of removing the detachable control panel of the cassete player at the end of each day: the spark thinned and the issue became resolved till date.

The battery end of the ML sparks very significantly. I do not know how to completly shut down the cassette on it as it were. The control panel is not detachable. I don't want them to mess up with the entire system as usual.

How do I resolve this issue? I appreciate your advice.

The spark is from the fuse board,I guess.if there's any slack among the fuse,it results to sparks and drains the battery quick. The battery wouldn't drain during the day because while driving the alternator keeps the battery charging even when there's a leakage on the circuits. But the moment you switch of your engine the current leaks faster due to spark & slack of one the fuse.

Google how to fix parasitic battery drain. It's very easy to detect the culprit.
