I was under the coach again to get a better look at all things. I ran the compressor and it was leaking where the plastic bowl and the solenoid meet. I traced wires that are in question. The two wires that go from the solenoid below the leak both go to the small " green board ". One wire seems to connect to a post. The other goes thru a connector like the one I am missing part to. It also goes to the board, but looks as if it is soldered in. It is tagged " to exhaust solenoid ".  The wire that has male only is tagged " to water trap." It goes to the green board where it looks soldered in. No female for it anywhere. I tried to release the plastic bowl so I can determine why it is leaking. I could not figure out how to release it. There is a black ring at the top of the plastic bowl, but I would have to get a channel lock on it.....IF I SHOULD TURN IT.  If I have to turn the clear bowl, and leave the black ring alone,I fear that I can easily break it. So....how do I get the bowl out and what should I do about the disconnected wire.???
hold the bowl and unscrew the black ring, mine was a little hard but hand tight. not hard at all to remove. MOT replaced my bowl 2 weeks ago or you can get it from the HWH web site. if your missing a part to the connector you can cut the other part of the plug that's pictured above and butt splice it back together or add a switch between the 2 wires to be able to turn it off if needed somewhere down the road. the other wire is a ground and mine attached to a ground post on a solenoid, just remove the nut and take the wire off and the exhaust solenoid will be unhooked. you can unscrew it from the bowl when you get the bowl out of the coach to a work bench or table..

Important:  I raised the question earlier in this thread that I did not think that an  01 engine compressor would pressurize the third tank that is pressurized by the aux compressor.    I have just not had time to pursue this further but did today.......two salesmen and three techs told me that the third tank is cannot be pressurized by the engine compressor in normal operation.

This is important if you lose the aux compressor and think that you can compensate for that loss and manage the slide bladder by running the engine compressor to provide air to the third tank.  IF things are operating as they should, this will not pressurize the tank but you will not know it UNLESS you have a gauge on the aux compressor third tank and can read and see there is not pressure in the third tank.  If you, without the gauge, think that you provided air to the third tank and move the slide, thinking the bladder was deflated, you may tear the slide bladder.  (The bladder is deflated and inflated by the air from the third tank)

Hope this makes sense, send pm and we can talk if need.  There is a way to fill the third tank even if you lose the aux compressor so you need not be stranded.  And, in my terms....not the techs or sales.....you I think may pressurize the third tank if a check valve fails and think it normal to pressurize by the engine.  At least I think I saw that several years ago when check valves failed due to desiccant dust.

And I welcome if anyone says I am wrong and sets me straight that the third tank is filled on the 01 by the engine.  But I thought not and I checked some experts today.

take good care of that aux compressor system!

Mike you are absolutely right. When I talked to Glen last week after you pointed this out, I asked him about it and he told me the PO had shown him how to do the "credit card test" before and after moving slide, to make sure seals are inflating and deflating. He said they were, so I assume that a check valve between main tank and 3rd tank is leaking by and pressurizing bladder tank. I believe he is looking for a place to put a gauge.

HI guys,
Michael, thanks for looking further into this problem for me. You too, Jim. I AM concerned that we are going to be able to use or slide when we leave here, Monday. I deflated and filled just fine, last week. As I mentioned above, I had spoken to members here, and to a tech at HWH, and all recommended  that I install a gauge. I was lucky to find a great supply house in Brownsville, Tx, and now have a gauge to install at the compressor. I cut the line coming out of the cylinder, as the HWH tech told me. Unfortunately, it is raining here, and I won't be able to install the gauge until it clears up, hopefully tomorrow. The joey bed would get soaked in an open position. I, also, found a metal fabricator in Brownsville who cut up (8)  2" x 2" x 1/4" tubing, for $40, so now I can safely pump up the coach and try and locate the leak, if there is one. I won't know anything until then. To complicate things, this campground is covered in sharp, little burrs that are even on the concrete slab. We can't walk our dog here....have to take him in the car to the nearby beach. So ......it' ALWAYS something....eh??

UPDATE:

Installed the gauge. At 90# compressor shuts off.  RESTARTS 1 1/2 minute later. Shuts off at 90#. Restarts 1 1/2 minute later. I think I have a leak somewhere. I will get under the coach tomorrow and take a peek. I think I might have a gauge on the third tank. We shall see. Any ideas ....I am listening.......

Try and find out at what pressure the compressor comes in at,may be a problem with the cut-in and cut-out pressures on the 12
volt compressor.

Watch the gauge you put in and the pressure should drop as air leaks from the system.

pressure usually set to come on about 65 psi and cut out at about 85 psi.

At the last Reply count, there are 83 or so questions and most by far are replies, answers and suggestions.

I got to looking back to check on a subject and the latest answers

Dan,

I was able to operate my slide, with the aux turned off, for the balance of our travels. If I understand everything that was explained here, I guess I had a leak in a check valve, as I always ran the engine while operating the slide. The trip included Quartzite, Mexico, southern Cal, and then to Moscow, Iowa, where I had to have a new seal installed due to a "pinhole" leak in my bladder. While I was at HWH, I had them go over my aux compressor, and explained EVERYTHING to them. I must have said " leaking check valves" half a dozen times, and asked how we could determine if they needed t be replaced. They worked on another part of the aux compressor, replaced a solenoid looking part, and it seems to be working ok. I don't know what else to say at this point in tie but will monitor the situation and update this as time goes on. Thanks to everyone who helped me with this issue. You all were very helpful and supportive.

time was about coach age that would get that bladder leak.....as did I, explained in thread about year ago.      was hard to find the leak, recall MOT was not sure at first I was right about the leak as it would seem to self-close and miss it with the bubbles.

glad you ok

Just competed a 10,000 mile USA trip with the aux compressor disabled. The coach has no slides. The compressor was running continuously when the coach was very unlevel, so I pulled the power.

Once HWH leveled the coach with the engine running, I turned HWH off and the coach remained level enough for a weeks worth of camping. The coach would list a little bit over a weeks worth of camping, but it was almost unnoticeable.

Now that I am back home, troubleshooting can begin. However, I am not sure if I want the aux compressor engaging while I am sleeping.

Glenn, I don't have the air system schematic for your build number but if it is like mine and there are no check valve leaks the HWH bladder tank (which is the only thing that feeds the bladder manifold) can only get air from the HWH compressor.

No check valve leaks is the key thing here.  Hving the engine pressureize this tank would be OK from my point of view.

you might run the positive wire up into the coach with a simple switch in the coach and then run the wire back down to the pump - in that way you could shut off and back on the pump from inside the coach whenever you wanted.
