AC relay? More Info 850 1996

AFAIK the superheat switch is inside the body of the compressor. If you look at the wiring, you'll see the wire go into the body and come out again before going to the coil on the end of the compressor. Obviously being a heat sensitive switch, it needs to be embedded inside the compressor whose heat it is sensing. To bypass it you just er... bypass the bit of wiring which goes in and then back out of the compressor body.

The black plastic sandwich component is the diode.

I say again, you need to know if the supply wire to the coil has 12v on it when the clutch disengages. Also - if it IS the superheat switch causing it then there will be 12v befroe it and 0v after it when it trips.... make sense?

If you still can't solve it I have another suggestion and that is the coil has become weak and can't stay on for more than 10mins at a time without stopping to cool off. I have a fix for this which works for me but see how you get on first.

Please be careful working around the spinnng belts.
