Air suspension

[Eric Johnson]

Phil,
Few years ago I had to replace air valve on our rear air suspension due to leak
problem.
First place I would check is the valves regulating air pressure to your front
air bags to
control level. Do you have one or two valves up front?

I have been experimenting the past two days. Actually, I've been wiring
the TV to use the same AMP as the Stereo Radio/CD system. So I have time
to monitor things while playing in the coach... With the air springs
deflated, the 120V air compressor will run every 15 minutes or there
abouts. With the air springs aired up, the 120V compressor cycles about
at 70 minutes.

Any thoughts on why the difference?

Mine too Curt, at least 70 minutes.

My compressor cycled about every hour presumably to replace normal air loss. I
have a leak at my step solenoid valve and have not solved that problem yet.
I have noticed the following:
The aux air system which operates the step, air ducts, stepwell cover, dump
valves and other stuff bleeds off rapidly due to the step valve leak but the
main air gauges do not. Don't know why?
If I start the engine immediately after the aux tank bleeds off( doesn't have a
gauge), and the main air gauges registering between 95-100psi, the low air
buzzer squeals until the aux tank is filled. That suggests the pressure switch
and buzzer are in the aux system??? Don't know why that would be either.
It sounds like a leak in the aux system in your case, and I don't know why I am
saying that.
Just more questions than answers. I gotta get my step valve working properly
before I can figure anything out. Let us know what you find, It could help me
figure out my problem.

I would guess that if you have your Jacks down that your dump valves are being
actuated.
