system is regular ac controls
all switches are 2 wire
all fuses are good
not sure about pressures but ac will work for about 15 minutes when it has set for awhile(like 4 or 5 hours)but once clutch kicks out it never kicks back in.



I have put 12 volts on compressor and it kicks in and cools good.I have not jumped relay but did replace replace it with a know good relay.I will try jumping relay tonight.the switches are 2 wire switches.the wires at HPCO switch dont have any power. Also there isnt any power at the clutch.I have put 12 volts to wire at HPCO switch and it works good.where does HPCO wire get its voltage from?thought about running a jumper wire to wire at HPCO switch and leaving it but not sure if it will hurt compressor or cause ac to freeze up???

thanks guys
