The A/C is not working all the time just intermittently. Normally works when the tractor is first started then stops functioning. Ever since i have had the tractor (bought new in 2004) the clutch cycles on and off alot. when the clutch stops cycling the a/c stops working. i have had the air gap adjusted before. i checked the clutch by jumping it straight to the battery and it worked everytime. engage with 12V and disengage without 12V. i think i have a different problem this time.
if the system is working properly it will freeze you out on low at idle speed. if it is not working it is pretty miserable in the cab.
looking at the wiring diagram the only 2 things that affect clutch voltage to the compressor are the pressure switch and thermostat (thermoswitch). it has a dual pressure switch installed in the inlet line(liquid line) between the receiver and expansion valve.
