Low air alarm in 2000 Monaco Diplomat

[jackie]

This morning, I went to check on our 2000 Monaco Diplomat DP..

When I opened the door, the low air alarm was going off. I have no idea why. I started the engine, let the air come up, and it was still going off. I turned the engine off, dumped all of the air, and the alarm was still going off.

I cranked the unit up again, and drove it around the block, the low air alarm going off the whole time.

I parked again, shut every thing down, and the alarm just keeps going.

Any thoughts. I can’t even find the darned alarm to under the dash, or the fused link that powers it.

Power to buzzer should be switched by main switch

The gage reads what it always has, between 60 and 80.

Everything works great, brakes, air ba suspension, but the darned alarm will not turn of, whether the key is on or off.

If I knew the wire that fed it electricity, I would disconnect it. Right now, I can’t even find the alarm, and I have the dash taken apart.

After 20 years the Lo air pressure sensor is either bad or wires loose. Doug

Wonder if more than just low air could be triggering the alarm?
