its not cold pressures r 20 on low side and 175 on the hi side ball is at bottom of glass . it keep shuttting off when i was charging unit thru low side when running.
Hi Daz man. I may be wrong but I think that is a low pressure switch and not a transducer. Obviously a continuity check across would confirm. I will see what I can dig up for you. Grizzly
Thanks Brian. Do transducers fail or are they reliable pieces of kit?



also do u charge thru the valve on the back off compressor
Spec on pressures
