We had an air horn installed on our Newmar Kountry Star. It seems to be "possessed" and will blow for no reason at most inopportune times! Like in the middle of the night at our favorite RV park! What could be causing that?
Air horns should be wired to teh ignition, so they can only blow when the engine is running. Try opening the circuit between the button and the solonoid to start isolating. If it blows with the circuit open, the valve is at fault. If not, the button or its wiring is the culprit.
