Couldn't bear to see an empty forum

Thanks, Jon.

My aux compressor seems to cut out at about 90 psi, which I think is just a shade too low. I would like to bump it up closer to 100 psi.

Once I figure out were the adjustment can be made, I'll let you know how I made out.

The next rally can't happen too soon for me, I'm really looking forward to learning more about this bus, although I understand that several POG members may require some recovery time from the last one....

If they located the aux compressor on yours in the box located in the center of the coach visble from the steer compartment the 120V line to it should pass through the pump switch (gray plastic enclosure).

You can adjust the pressure when you remove the cover.



This is a good time for you to add a system pressure gauge to the unregulated auxiliary air system manifold on the floor of this compartment. I think Mango has pictures that he posted.

MIne has guage under driver(outside compartment) and it says normal pressure is 45 LBS and that is what it has, not 90 etc. However today I noticed a long run and I opened compartment and your could hear air rushing out so I cut off pump and no more sound and it is holding pressure. Do I have an adjustable pressure that I could set down to keep pump from continuing to run after reaching a level and then just letting air out???? Thanks Dan & Jo

Dan,

I lack knowledge of Vogue specifics, but I suspect all our coaches share the need for pressure regulated air and unregulated air pressure.

For example, when your coach is running, the engine air compressor is providing 120 /130 PSI air to your auxiliary air system. That includes your entire coach suspension system. That is the system into which your auxiliary electric air compressor is plumbed. While not all coaches can be leveled with the air pressure from the aux compressor a lot can and are leveled, requiring at least 100 PSI.

That pressure however is too great for some of the aux air needs such as the air floor. Those components which could include the generator air bags, the bed lift, and pocket doors. Unregulated air may be required for the door lock and the air bellows for belt tensioning. Prevost definitely requires unregulated aux air pressure for those components, and in the case of the air bellows regulates them in the engine compartment. 45 PSI is not enough for them.

If you check your system you are likely to find you have both regulated and unregulated air pressure.

As to the running pump and the escaping air that could indicate the discharge pressure line from the pump may have failed and the system has a check valve to prevent the built up air from backflowing. I had that happen on my shop air supply once.

That gauge could also be the floor slide regulated pressure, my Marathon had a gauge with that same type label. Like Jon, I'm not familiar with Vogue.

[Danss]

I would assume my 45 lbs is for floor slide, seat and toilet (no pocket doors) I have 2 guages on Dash for all the heavy stuff. I must have a faulty switch and the compressor is not shutting off at correct time. I just checked pressure again and it is still holding 45lbs(Of course no use of the three above units)

Jon,

Thanks so much for the great pix!! Mine looks exactly like that and I can't wait 'till daylight to adjust it!

I know, a "real guy" wouldn't show such restraint and already be out there with a flashlight and tool box close at hand....
