I am sure most ya all have seen my 06 F650 car hauler- it has a 5.9 Cummins - it has air brakes - yesterday on the highway the air horn went off and it appeared I had NO AIR pressure - however I had good brakes and the air bags were up -- the air gage went around and it only appeared to have 0 pressure when in fact it had over 200 (way to much) pounds -- my kid tried adjusting the governor to no avail -- any ideas?????? call 314 920 3725

Lenny,
Sounds like bad governor, or unloader valve in compressor is stuck. It should have a overload/ bypass valve to not build that much pressure, or it will destroy the compressor
 
ADR is getting it Monday if I cant fix it tomorrow -- fairly sure it is the govener -- however ther is a loose bolt on the compressor ?? kind of lost with out it ---thanks
