@Don
This might be a stupid question, but in your post above, the first picture shows the “120vac Versa brand normally closed solenoid check valve”.Given that it’s normally closed (to keep air from bleeding back to the compressor) and assuming when the pressure switch turns on the compressor it additionally opens this valve ‘electrically’ – what functionality does that provide verses a standard passive check valve?

I know of one Aux air leak that’s probably never going to be fixed. The sliding door to the bedroom has an air cylinder that’s going to require the washer & dryer on one side and the refrigerator on the other side be removed to remove the door air cylinder for repair. Not worth the effort. I just put a shutoff valve in the line and turn it off when not traveling down the road.
My aux tank stays up when driving, I do need to check the wet tank and governor for leaks. The system is not leaking much right now so my incentive is low. LOL

Hummmmm:
So it could leak back through the main line and out the compressor with out affecting the brake tanks. Will have to go down that road and see where it goes.
Jon:
Have done the drain down test per your suggestion, safety valves work. On a side note; before I replaced my brake relay valves and had a slow leak down on the brake tanks the Aux tank would drain down to zero with the brake tanks. Since replacing the brake relay valves I have basically no brake tank leaks, just a slow leak in the Aux tank.
As noted, brake tanks stay at 120 PSI for months before slowly leaking down further (maybe 1/2 PSI a day if that). Aux tank will drop to around 70 PSI overnight, then take another 4-5 days to reach zero while the brake tanks remain at 120 PSI.
The leak is in the Aux and is small enough that it’s not a priority to fix but more a challenge

Hello Jon – in a Liberty configuration, would I be correct in that the 120 vac aux air compressor psi setting “switch” is the “pressure switch”?
Wondering if it can leak / leak backward….?
Seems if it were leaking backward, the Liberty install Parker spitter air water separator valve would be leaking out of its bottom drain…?
Is this correct? Wondering if the Liberty installed GAST compressor can be an accessory air leak point? (and how)
THANK YOU!

It covers the top bus windows above the windshield and on the side above entrance door and driver’s side glass

Hello, where is your aux check valve at on your coach. We have a 99 H. Featherlite conversion. My aux air is only building to 60 psi. Started suddenly. Replacing a pitcock on the small tank passenger side front to start.

Don, how long does your bus sit between runs, and how do you drain your batteries down to 50% SOC?
-
Buses are rigid they won’t twist like a fiberglass RV, Before this Prevost we had a Foretravel U320 a good quality build, but it would twist so HWH air bag level would adjust left to right on front in level mode, Our standard level system only does rear left to right and 1 on front, But you move left or right up or down the front follows, I’ve never had entrance door jam for being twisted. Lots of fiberglass had windshield cracks from twisting, Monaco even went to tripod 1 large jack in front and 2 in rear. when you set ride height you set air bag gaps in rear between steel plates and make it level. It is like 11 to 11.5 inches plus or minus 1/4 ?? I can’t remember

Thank you Jon.
That’s why we did it last time per your advice and we fortunately haven’t had any major troubles except one airbag that Prevost Nashville spotted on a DMI.
We’ll just start the process of getting it scheduled.
Thanks again Jon and have a good weekend,
Chris

Mike Yes! Now the DN 50 12v is set to 13.8v for the old Lifelines Don left his alone won’t charge Lifepo4 up to 100 percent, Jonthan Fine set his to 14.2 and doesn’t seem to be a issue, What does the DC to DC charger do different, and does it connect to 4/0 cable or between regulator and DN50?? If it is like this charger how would it wire up??

was also leaking where the shaft for the arm comes out the main body of the ride height valve.

Mark, I knew there would be some push back from the grouchy ole guy in Knoxville, so I got your back. Even fast Ricky went to the dark side. My reason was modern technology, 12v systems and warranty. And I love slides so much, what possibly could go wrong with having 4 or 5.
C’bus, glad to hear from you, aren’t you ready for batteries?

Emerson Thermostats Emerson 3F05-1 Snap Disc Fan Control: available on amazon = $13
is what I use for my 2nd fan.

I hope everyone takes note of the two sticks and staples owners.
If their Prevost substitutes were so good they wouldn’t be constantly trading.
I want to hear the reasons.

Can’t help with the inverter issue but, Headhunter sells factory rebuilt pumps for half the price and warranties them. I have installed a few on boats I have worked on with no issues.
Many of the pumps haven’t even been used. People purchase them with out checking the voltage requirements, receiving the pump and realizing it’s AC voltage not DC, then return it unused.
