Beaver Air Leveling System

[ImagineIF]

Here's one that took a while to figure out. My Beaver has the optional air leveling system. This system includes an axillary air pump and tank to ensure air is available when the coach is parked. When I bought this 2008 unit two months ago the pump would cycle on and off ever few minutes. The selling dealer thought it was the pressure sensing switch. I installed a new switch--same problem.

The problem ended up being the pressure sensing switch was i nstalled in the air line between the air tank and the compressor. This line has a one way check valve at the tank, as it should. So, when the air compressor bled down, which is expected, the pump cycled.

Switched moved to the other side of the check valve and it works great. I bet it was this way since it left the factory in 2008. Anyone else have this system on your 2008 Beaver? I'd be curious if others have experienced the same issue.
