there is a switch on the high side line that trips at 150 on the high side. it thens trips a relay to turn on the fan. the gorund for the relay is the pcm. you need to have the system inspected by a guy that is good with electric. Roy
Thanks Roy but the switch is on the compressor. Fan comes on at 300 Psi and works great after I replaced pressure sw.
