Battery Drain, PLEASE HELP...

[chytaan]

Hello:

I own a 1997 Mercedes S600. The last few weeks, my battery would need to be jumped everytime, i need to start the car. Then when i turned ignition off, i couldnt start the car again, unless i jumped my car.

I took my car to my mechanic, he said that my battery was completely gone. I purchased a new battery, but before my mechanic could install it, he checked for a drain and found one.

He put the ammeter to the negative wire, to see if there is a drain, before installing the new battery, and there was a reading of 0.1 or something to that affect. He told me that it should be around 0.01, but not that big of a draw like i am getting.

Then he did the usual, pulled out each fuse, to see what is causing it, but nothing came out definitely. He even tested the aftermarket stereo, but it was only getting out around 0.02 . There is something that is drawing around 0.1, and its not the fuse according to him, and that a lightbulb should not draw that much.

Can someone suggest what might cause this?

I did some search, and read that something in the alternator components might be the cause, other suggested a corrupt positive terminal wire, some suggest alarm system or climate control..

Any other suggestion on what would be causing such a large drain????

ANY suggestion appreciated.


Thanks in advance
