Dan did you put all those air pressure gauges on there? Or did the coach come like that?

Everyone is contributing to this discussion regarding working on Harry’s coach so here goes a thought:
In the past, if I remember correctly, Harry… you stated certain “mechanics” came to your coach and tried to fix it but you had significant issues with their expertise. Based on your desire and interest to work on the coach yourself and being certain that issues will always be present, I would not give up on the idea of trying to find a trustworthy mechanic who could, through time, learn the coach and who, with your assistance, could be more available for immediate consultation and assistance in solving issues.
What I am suggesting is a “working relationship” with a capable person familiar with both recreational vehicles and also familiar with the more involved intricacies of a Prevost conversion. Through time, we developed such a relationship and it proved very valuable indeed.
This may be an obvious solution and one that cannot be accomplished because of logistics and a lack of available mechanical talent ….but it is a goal I would continue to aggressively pursue.
Best,
Pres

Good news, our offer has been accepted! We are almost officially Prevost owners. Bryan is flying out next week for the inspection. Wasn’t able to get Taylor Tours to do the PDI as they are booked into February. Planning on spending two nights in the coach. And head from Phoenix to FL on the 18th. So excited. Again you guys have been a tremendous help. Looking forward to getting to meet everybody on the road some day. Thanks for the info on the satellite systems. Not sure when we can get the coach up to Jeff’s. After driving across country we won’t be using it again until March most likely.

Ditto Jon’s caution on the live plug, verify it’s dead even after unhooking shore power and shutting down the house battery and inverters.

Robert,
Just for an example, my neighbor at my storage facility bought a new 2016 Marathon. We happened to be at the Prevost facility in Goodlettsville, TN, for service at the same time.
We were ‘talking coaches’ and his batteries are above the rear wheels on the drivers side where we have our Espar/Webasto heating system.
His Webasto was in the engine compartment on the passenger side where we have a storage box. Because we have Lithium Ion batteries, we only have 3 house batteries in the compartment in front of the wet bay on the driver’s side.
My neighbor probably has 8-10 house batteries. Everything in his coach seemed to be in a different place than ours. Nothing wrong with that, just different.
We have four inverters, he has two. His coach was a three slide with bunks, our is a four slide which will give us a smaller kitchen (we don’t cook). Our four slide gives us the extra seating that we wanted in the living room. Each of the two facing sofa’s turn into beds which came in handy when taking my two 13 yr.old great nieces to the Hot Springs water park last summer.
Safe travels,

I’m with Jon & Dianne. The initial depreciation on a new conversion is horrendous and being a newbie, it’s almost impossible to know exactly what want or what your needs might be depending on your use of it. There seem to be two sweet spots with depreciation (and lets not kid ourselves …it’s normally our biggest expense), either buy one where the depreciation is just about out of it i.e. ’96-2003 XL or one where the depreciation has slowed to a more manageable level, i.e. an ’04-06 XL(H..a little more money) with an eye to trading up in the foreseeable future. That way why you’re using and enjoying it, you are also figuring out what you need and want in the next one, and if you’re like most of us…there will be a next one. Geo.

At one time I had 2 circulation pumps, one dedicated to the Webasto and a second associated with the OTR. I think now I have only the Webasto pump and I presume it is tied in with the OTR. You might be OK but verify when stopped and parked you are getting circulation of coolant through the Webasto.
-
Jon, you know we have 2 24 volt circulation pumps that come from MP Pumps in Michigan. One in the engine bay and one mounted next to the Webasto unit. So I presume your saying I need both of them running for adequate heat exchanger flow.
Note: there is a third pump imbedded in a copper tubing or brass bulge near the Webasto unit too.

Hi folks,
I want to thank you all again for your help and let you know I found the leak. It’s a short hose less than 12″ long that I believe goes to the radiator overflow (on the right-rear by the firewall). It was leaking and with closer inspection you could tell it cracked. I’ll buy the new hose next week and get her all fixed up! I’d expect I’ll have to replace any antifreeze i lose right? I checked the site glass and it showed half full as required, so that’s good.
I took the bus for a good run today and it ran like a champ. I’ll be taking it up to Jeff in the next week or two to tackle the Jake Brake and leaking belt tension valve issues.
Thank again everyone for your input…
Harry

I think your vintage coach used a black cast metal enclosed voltage regulator mounted above the chassis batteries and it might have had 4 wires. A battery wire (positive), a field wire, a relay wire, and a ground.

Beware of the inferior quality counterfeit Haldex height control valves. They are cheaper but don’t last as long.
Look Here.

Ahhh BA, the horsey’s still had to eat.

Rocky your suggestion is valid if the system is tight, but if the cylinders or bellows leak air you have to stop as often as necessary to repressurize them.
One thing never to fool with on a coach is a cooling problem because a perfectly fine motor can be converted into a boat anchor very quickly.

The air dryer removes water from the air system. That is what it is designed for. However, if the air compressor is wearing out, engine oil can also appear in the output from the compressor. This would be visible under the dryer as some of it gets exhausted with the water each time the dryer goes through a purge cycle. Not all the oil will exhaust though.
Oil will eventually cause the dryer to become inefficient. It is another good reason to change the cartridge often to keep the air system as dry as possible.
I wonder if you are seeing some oil drips under the dryer…..

10 minutes may be about right if you are draining the wet tank. The leak is downstream of the regulator and it has to pass around the o-rings in the cylinder so it is throttled pretty good. I don’t think it can overcome the air compressor supply like a failed air bag but I would try and have it fixed at a convenient time. It can go on your list for the next trip to Jeff.
It could be the regulator, the valve or the cylinder o-rings. I know I could hear mine but don’t recall if I ever felt it. I know I replaced the valve and rebuilt the cylinders don’t recall about the regulator without checking my log book.
Based on your description, I think the big swoosh your hear is the air dryer cycling. Next time see if it happens when the air pressure is about 120. The air dryer purges to drop pressure in the dryer housing and drive the moisture out of the dryer material. That is normal expected behavior.
