Ray, Thanks for the suggestion! I'll check everything at this point.

I've recently purchased our 2006 Monaco Camelot 40PAQ. When turning the ignition key to ACC the LOW AIR alarm sounds until adequate air pressure builds then shuts off. But I now have a second alarm when ignition is in ACC or with engine running or off. There are no associated warning lights lit on dash. With ignition switch at ACC for air dump there are now two warning alarms sounding. When air pressure alarm shuts off, I still have the second alarm sounding regardless of engine running or off. Does anyone know what this second alarm is? Thanks, Ted and Nancy C
