I need a Wiring diagram to my Cooper S Automatic 2005, because the car looses power from the battery. Does someone knows a place where I can find a diagram, which shows where all the negative wirings is located at the chassic. I have a lost on 0.3-0.7 Amp from the battery, with everything shut down and door closed and key removed. So in a few days I have no more power on the battery (it is a new battery).

 

Uploading right now.

 

 

Thanks a lot, I hope I can find the problem now.
