What should be the correct cycle rate on ac clutch?
anyone? I replaced the pressure valve on the ac with an adjustable one and I cant seem to get it to cycle at the correct rate. I need to know how many times per minute or what have you it should cycle.
Thanks

AC compressor will cycle depending on head pressure. When the pressure builds up too much the high pressure cutout switch will disengauge the clutch. If there's little to no air flow across the condensor, the clutch will cycle more than normal.

The proper way to set it is with a set of ac gauges to watch the pressures.
