Hooked up my gauges to high and low ports air conditioning on. High and low read 50 psi like the compressor is not engaing. I replaced the compressor and expansion valve and still the same thing. The compressor does not seem to have a clutch.It just spins all the time.There are 2 plugs on the compressor.One must be to engage the compressor but where does it get its signal from? Any help would be appreciated.
Thanks
