I am looking for forum posts information on how to test the compressor solenoid, test the low pressure switch. I can't get the clutch to engage is why I was not able to give hi/lo readings. Can some one guide me to some posts that have this information? Thanks, Larry
Read first with the compressor off. Both pressures will be the same. This is a test to see if there is any refrigerant at all. If it is less than about 50 psi, it is normal for the compressor not to engage because nearly all the refrigerant is gone.
