just did it. Worked perfectly. Awesome! Thanks again.

After I installed new batteries two years ago my Trace inverters do fine when switching from shore power to generator. If the batteries are in float with the shore power connected and I switch to generator they stay in float. They do the same when going the opposite direction as well.

However, Tom, mine does the same as yours when the trip is over. I will be paying attention to see if anyone has answers.

I recently installed an LG 42″ LED (2014 model) and matching sound bad in the drop down mount in a Marathon. It looked great. I wouldn’t say it didn’t require a little planning and work, but it wasn’t that hard. This model TV is great. It’s a SMART TV, with very good resolution and refresh rate and priced right.

If you were in my area I’d do it for you.

MM…

I envy the fun you are having… your coach will be gorgeous !! can’t wait to see it.

Cheers,

George and Corey … you back yet? or still on TN?

I believe your last two questions were answered, but here they are specific to your coach. Liberty has modified the Prevost system, but the modifications have no affect on what has been discussed.

The aux air system is what provides the air for the suspension, so any and all suspension functions are at some point tied into the aux system. More specifically the tag axle lift also gets air from the aux system.

The 3 port Norgen valves can be installed so the air goes through the normally open path, which is what is happening in the case of your coach to keep the tag inflated along with the drive axle air bags. Prior vintage coaches had reverse logic that required aux air system pressure to hold the path open. On your vintage coach your aux air can go to zero PSI and the air bags will remain inflated as long as there are not any leaks.

Didn’t you say the tag air bags were not getting air and that as a result the axle weight (when I finally learned how to read) was only 6000 pounds? What has changed so it is getting air?

Make that 2 black and silver plates please.

When I look at the Prevost Technical Publications page, Pneumatic Diagrams Index, there is no where to put in my “X” and last four digits. I did leave out my year and came up with a diagram that fits my coach number and year.

My bus shell fits the second from the bottom box. A Bus Shell XL-40 (M) with IFS. And I am within the shell # range. I am assuming the (M) means motorhome.

I think I see two Norgrens downstream from the air bag. I only see one front ride height valve on the drawing.

Prevost Ft.Worth just called and said the passenger front air bag was lower than the driver front and made the adjustment. They also replaced a “Berkett” valve on the Tag Axle, as it was original and had a slight leak.

Thank you for everyone’s help. I am out of computer range fro the weekend, so I will update you Monday on any other progress.

Thanks Tom, I appreciate it very much. I guess it is a throw-back to my military days. When I was in the Navy they would find something amiss, and the general idea to fix it would be to “wax it and buff it.” It just sort of morphed into, clean it up and paint it, in my later years.

Coming home on my first leave, my grandfather (bless his heart) asked me, “What are you doing in that there Navy son?” and I said, “I am assigned to a VP Squadron out of Jacksonville Florida.”

He then said, “What is it you do exactly?”

I replied, “We fly around all day long looking for Russian submarines Grandpa.”

He then said, “What do you do with ’em when you come upon one?”

I replied, “Well Grandpa, usually we just wax ’em and buff ’em, and then send them home.”

You are absolutely right “paint & chrome” don’t get you home. Coachnet, the Big Hook do the job most of the time, for everything else, there is MasterCard (now Tom, I ask you … wasn’t this priceless?).

Watch those right-handers.

I believe I had the awning to which you are referring on my 1990 Marathon. In 6 years of ownership, I only had to perform repairs once when either a lock failed or I forgot to lock it and the wind got it while I was driving…big noise. Thereafter, I installed 2 travel locks. In my opinion, the major drawback of the awning was that it was an effort to extend and retract (I would often retract it if windy) and I found myself not using it as often as I would have liked.

Current coach has the Zip-Dee Autoawn. I use it frequently due to it’s ease of use, when it works. It is a complex unit, not very reliable and fairly expensive to maintain.

I did install a Girard on a trailer I used circa 2002. In the 2 or so years I used it (frequently) maintenance was limited to a single minor adjustment. It’s major issue was that it did not shed water well and could not be used in the rain.

I’ve also had experience with several of the automatic awnings which come as standard on the ‘plastic coaches’. I have found them all unsatisfactory.

If I were in your position (I’m pretty darn close) and willing to go through the trouble of an upgrade, I think I would do more homework and install a modern automatic Girard or Zip-Dee unless there’s another major player in the game now.

Thanks Gil for that link. I’ve been using the diagnostic
software on a laptop to view the parameters and my intent was to stop using it
once I was convinced my regular analog dash gauges were reading correctly. But now I’m hooked on the other information
available on the diagnostic software. The problem is there are no options for
gauge styles or size with factory software. So I think I’m going to integrate a tablet somewhere in the
dash with the VMSpc.

Tom so what system do you have in your Marathon? I have the crestron with no problems at all. I did up grade my system to an I-pad to get rid of the bulky control box.

[JIM]

We were in Las Vegas prior to the Tampa show and the roads leading to Las Vegas are all OK for a bus and toad. No problems at all.

[JIM]

This topic is hilarious. For someone who doesn’t want to talk to strangers along the journey, you are inviting conversation at every stop with an attractine nuisance and how will Roger and Mickey get into that back seat.

Just sayin, JIM

[JIM]

You are correct:

Standard gauges, but the headlight and marker switches are the CC tri-color buttons.

(And, I did find the drawings, but wiring in diagrams not matching what is actually in the coach.)

Suggestions on diagnosing the board/component failure? (If I’m not using the coach for a week or two, should I pull the board and ship it somewhere for repair?)

How might I reach Miles Ciro to request his help?

Thanks!!!
