My boss has a mack dump truck guessing 70-80 year range..ill have to check service manual on monday... Im trying to get ac system as cold as possible, based on outside temp.. Since the mechanics wont do it im working on at when i get a few minutes... Im trying to get low pressure at the right level based on temp outside, two problems i have too much freon, get damp warm air, too little freon same issue... Im wondering if anyone knows the avg cycle time a compressor runs before shutting off for a bit. Right now it only runs forvabout 10 sec then compressor shuts off.. I notice when i take some out on the high pressure port the compressor stays on longer...i dont have the dual reading gage, only the cheap can gages to read the levels... One gage says its in the med range and another says its in the high range but when you use the temp adjuster for like 85 current temp says high range is ok.
