Sorry guys, the battery is just draining, not arcing out. My old lady neighbor that sold me the car told me that's what it was doing but it is not arcing....LOL. I finally got the car started after a very long charge and moved it to my garage.

Thanks for the tips on diagnosing the problem. After searching the net, it seems like one of the problems with Mercedes is battery drain. I found many topics on this problem.

Thanks again,

John
