All,
I installed a good quality gauge at the discharge of my little auxiliary air compressor and noticed the shutoff at 140 psi. I was with the understanding this should be set at 120 psi. Has anyone else had this much pressure?
2010 Nimbus, ISM500.
Thanks, Mark
Mine show 126 on both gages on the high side at the glass dash . My coach is #6527 so they are first cousin's at least. ;D Brad Metzger
Mark,
You're correct. It's normally 120 psi. Steve says it sounds like someone adjusted it up so they could use the aux compressor to inflate their tires (generally not the best use of the aux compressor).
BTW - you own one of our favorite FTs ever made ^.^d We seriously debated buying it several years ago when it was first offered for sale at MOT.
I think that pressure a serious defect, not fixable, and Mark needs to sell to Steve and Michelle, then they can sell their 03 to me! ;)
OK, I've done the research with the compressor and it's not worth fixing, a total loss, complete RV is worthless... looking for any offers! Haaaahahaha :P
I will start the bidding with $2,000 cold hard cash (some of it will be pennies). :)

I will throw in two gold Krugerrands too boot! :D
and we will throw in a bunch of "loonies" and "toonies" direct from Canada, and a few Euros left over from trip!!
What a deal!!

OK, it's a deal but you have to roll the pennies, my liquor store hates it when I walk in with a bag of pennies :D
Don't need no Kuggerands, chocolate gives me heartburn. Loonies and Toonies, I live in East Texas... got plenty.
I think we lost the "Technical" part of this thread, but I could be wrong!!!
Have a good one my comedian friends!
BTW, I will look into adjusting the shut-off pressure on the pump and bring it back down to 120psi. Most of you could do this in your sleep.

Mine goes up to about 138psi on the gauge at the aux compressor, dash gauge reads up to 132psi.
I have not been able to trace out all the air details on this coach but I will.
I would think the gauges on the dash are the two air systems for brakes and not the HWH system? Does the HWH system tie in to the brake system air?
I can see them being tied together as a convenience but a check valve would be required to isolate a leak on the HWH air.
Thanks all, Mark
Not sure about the newer coaches like yours, but on our '03 there is a switch next to the driver that's labeled "air tank". If you turn in on it links the HWH side to the brake air for the purpose of starting to air up the coach without running the big Cummins. Generally to be used just to be quieter and more considerate to neighbors before pulling out. The switch operates a N/C solenoid valve and I believe there is a check valve in that line (but double-check your air schematic to be sure for your coach.)
The switch should not generally be left "on".
Yes, makes sense but there is no switch for air tank on my coach. Thanks for the information, Mark
