I'm trying to get my Air conditioning to work I can jump the compressor and get the air to work refrigerant pressure is right on the money when its going. It has no electricity getting to the compressor. Ditto the cycling switch. I can jump that direct to positive and it works. Circuits are hot into and out of the control head.Only thing left is the low pressure cut out switch and I cannot locate it to check the circuit. Where is it? Referance to a picture or diagram some where would be real helpful.
