2006 CLK 350 no crank no start, blows fuse 53 if you try to turn the ignition to crank position. 12 volts is present on one side of the fuse slot, the other side shows direct ground this is checked at the fuse in the engine compartment. Anyone have a wiring diagram of where that fuse leads? I think it goes to the start relay which is good but I'm trying to find where the direct short is. Any help is greatly appreciated.

Fuse 53 blows each time you try to turn the ignition switch to start position. One side shows 12 volts the other side is grounded.

 

Hope this drawing helps

Connects to starter relay and Engine ECU..

 

Thanks for the info! I do appreciate that!
