hello. please help my : BMW F20 1 Series 116D 2.0D 116HP N47D20 engine
at service they changed my ac compressor, but even with enaf pressure and refrigerant dont work because bad electrical short-circuit between compressor wires on car
they have 3 wire and all are short circuit: how/where i can find the electrical diagram of those wires?
what exactly are they doing? even i am electrical engineer i cant figure it how they work
i assume that one is 12V and one GND...but what about the other one?
what happen if i connect them directly to + battery (of course thru protection)? should work?
