Air Dryer Purging Air Every 15 Sec

[GunRunner]

I think the black plug you are referring to was screwed into the exhaust port. I removed it last night thinking that was going to fix it and it didn’t. The plug appeared to be one way with a little rubber flapper. The new Bendix governor that I put on today has the exhaust port wide open.

mostly it is just open straight from box

also on volvo engine you can use shop air on 1.4inch line that goes to air compressor and see if it holds air

tried this on cummins and air escapes fro safety valve on compressor head
do not know if its good or bad but had same situation before with purging every 30sec
unresolved :(
