Hi all, I know this is one crazy arcane question, but here goes. I need to jump start a vehicle but upon opening the hood of my leased MB C300 sedan, I discovered that most of the stuff, including the battery proper, is under one plastic panel or the other (which I’m loath to move because it is a lease). The only easy access is to the positive port, as if to discourage using the Mercedes’ battery to “donate” a charge to another vehicle, because the way I learned it, you have to attach the red clips to the positive terminals on both vehicles’ batteries, then attach the black clip on one end to the negative terminal of the donor vehicle’s battery, and the other one to a metal engine part of the “jumpee” vehicle.
If anyone can steer me to a way to do this I’d appreciate it. Maybe you don’t have a C300 but another similarly afflicted vehicle and I’m just missing something obvious.
