AD9 dryer purging every 2 minutes

ill have to get sime time to check all that... basically tossin parts on due to lack of diognistic time! all parts pretty cheap and good maintenance item i guess ! l keep movin forward and let ya inow what i find thanks

 

so i was installing a new set of unloaders, and herd a very small air leak i didn't before, turns out there is a pin hole in my wet tank where it rests against batt box(379). so i replaced the wet tank, unloaders and both lines to governer for new, i put a gage in my wet tank to see if holds pressure and for how long.... it holds n dont drop for 10 minutes... now what is happening is dryer purges at just shy of 130psi, once pressure drops to 120 psi the compressor kicks back in and blows dryer at 130, this equals out to be a purge every 10 min loaded n rollin down interstate.... its allmost like the cut in pressure is to high it should let pressure drop to 90 then build? at this point i got new unloaders, new wet tank,new govener,new dryer and 2 new lines to gov

 

id say the cut in shold be 25-30 psi lower than the cut out? as it is now it purges 130 psi starts building again at 120 psi... would like it to drop to 90 psi before it starts building thus purging less
