I've asked you guys about this before but you've asked for pictures. So, first tell me how to post pics so you guys can see what I'm talking about.

In the leveling system location on the dash are four, two-way switches and a light. Each with has a red and green light and the light has a red light and a green light. My compressor runs and runs but only gets about thirty pounds of air so I have a serious leak somewhere. Inside the driver side access panel where the steering shaft is, are a bunch of solenoids with air lines running in and out. There is also a mysterious box about four inches by four inches by four with an air line coming out of it. It has a label on it that says, "Furnas." There are no other markings anywhere. I suspect a PO was an engineer and designed and installed this system. The rear suspension has been upgraded to the two bag system. the air line has a very high quality shut off valve that goes to an aluminum manifold while two other air lines go to the ride height sensor or whatever it's called. From the manifold, which also has a pressure gauge, is an air line to each air bag, again with a nice shut off valve.

Does anyone know anything about this system? I have no info at all. Tell me how to post photos and I'll throw up some pics so you can see this confusing collection of hoses, wires and solenoids.

As always I am so thankful for this community so willing to help others. I try to repay by chipping in my two cents when I read a post about something I've had experience with. Life is good.

I can simplify your air suspension life, and get rid of a whole bunch of
unnecessary hardware in the bargain with the wireless remote system. It is
self contained, only has two air hoses from the manifold to the air bags,
and can be operated from anywhere near the coach with a remote control
similar to a garage door opener. If your compressor is shot along with your
control valves, price is about the same. If you are interested, pm me.

Gene,

Thanks but no. My system is more complex with six solenoids, relays and that mysterious 4 inch square black box with one wire and an air line going to it that tees with the main air line out of the air tank.
