Compressor solenoid

[Larry Davick]

Is the compressor solenoid anything special, or is it simply a SPST 30 amp solenoid?

I think the compressor is working too hard and I noticed that the solenoid was hot. Then I noticed the the Brown / Green connector seemed to be
melting. It's likely that my old Dana is waiting for loved ones to pull the plug. I've got the coach at Jim K's place now and asked Nick to simply
move the plumbed schrader and shutoff valve so that I can actually reach them when the coach is low, so that I can manually set the ride hight. That
very nice feature is now located behind the tire in an absolutely inaccessible place when her belly is on the ground.

I've added wireless air to my wish list since the 6 solenoid + compressor are going to get expensive over time.

Here's an interesting newbie factoid - if the coach is low and you want to put your bottle jack under the bogie, you'd better call a panicking mother
to lift up the coach first. Without a Jack Hook you will be SOL.

Relay - not solenoid...

What part exactly are you asking about?

I have a 1976 Palm Beach. There is a relay that looks like a horn relay mounted on the front wall of the cabinet where the compressor is. I have
never had a problem there, so I have never researched that circuit or part.

It took a while to find it on a GMC wiring diagram and it appears the power for the relay coil is from the control switches for the electro-level.
The relay points are protected by a 30 amp CB and only the N/C contact is used.

So in my opinion any 12vdc 30 amp relay could be used. But why not just go get a GM horn relay.

I do not remember any solenoid.

Any 30 amp or bigger relay would be fine. But if the wire is melting it's probably not the relay thats bad(yet). Sounds like an undersized wire or a bad connection

Before you buy a Wireless Air look at MicroLevel. It's all that and then some.

MicroLevel, what is it good for? Microlevel is an upgrade for the Power Level and Electro Level ride height control systems that came stock in the GMC Motor home. These systems work quite well and are pretty reliable.

Keith,

That's a slick system!

I love the control panel and the simplicity of the thing. I keep vacillating between going totally manual, fixing the current, or updating to
something like yours. My pocketbook usually speaks louder than my want's or needs, but Christmas is coming and I've been a very good boy this year...
