Alarm

[wolf1281]

We have a HR Endeavor. The low air pressure alarm and light were coming on. Had both sensors replaced and a new front leveling valve installed. Picked up the coach today. Got about a mile from the repair shop the audio alarm sounded but the low pressure light didn't come on. Air pressure seemed normal. Drove about another 1000 feet,the alarm went off. Pulled into a parking lot,turned the coach off and called the shop. Said bring it back. Started the coach,the audio alarm sounded till I drove a short distance then stopped. Got back to the shop naturally the alarm would not sound.Left the coach. Mechanic said he would call tech support. Has anyone ran into this type of problem before? Any help or suggestions deeply appreciated.

Wolf.....It's the pressure sensor on the bottom of the Parking Brake switch. It's about $45.00 and you can only get it from Monaco. You have to remove the side panel near your left leg, drop the Parking Brake switch out and screw the new valve in. It's brass and about the size of your thumb with two wires attached.

Here is the part number:

Pressure Switch

If your HR Endeavor is an earlier model built on a Freightliner chassis, your switch will be mounted on the driver's side frame rail just in front of the rear axle. Switch available from Freightliner in Gafney.
