Help! Air not building
In storage lot.
Turned engine on , air built to 120, blew off a few times as I was checking and adjusting tire pressure. Today is go to pine mountain day. Got to wheel #4 and heard the 120psi blow off that sounded weird a little... maybe storage buildings reflecting sounds. But no, air pressure going down with wvery use, and not building back up. Low air light on at 90psi. Also, engine oil pressure gauge pegged at zero, which is a new symptom, I think separate. Paul Text 832.816.5825 and i will call back from whichever phone has more juice.

Has the coach been sitting Paul? Check the simple stuff first. Rock the suspension switches on the dash or even bumping the bus forward might free a stuck valve. If it's building to 90 lbs I wouldn't think it's a bag. Can your hear a big leak somewhere?

sat for a week. Ran every other day. Built up to 120, but now there seems to be no compressor output... So as i use that 120psi i get no new air in the tanks. Governor is apart at the moment. With engine on no air coming out of the governor, whether or not i am pushing on the shuttle inside it.

Could also be a blown line between the compressor and the dryer. You can't hear the leak over engine noise. Been there. Will it air up from shop air?
