This post is what I have found on my coach which has the HWH leveling system.  If your coach is not exactly the same, it will be similar if you have the HWH system.

I've been doing an air line schematic to complement the rear suspension schematic that I've already done.  Newell has basically set up three air systems that interrelate.  The black air system is the brake system.  The red air system is the suspension system.   The blue air system is the house air system.  The colors are designated by the color of air line that Newell used to "feed" the separate systems.

The first schematic is of the air lines of the differential lock solenoid, rear distribution block, rear air dryer and the rear six pack.  The rear distribution block is mounted on the vertical wall just forward of the right rear engine compartment.  The rest of the items are located in the right rear engine compartment.  Follow the 1/4" black air line from the "in" of the differential lock solenoid and it will take you to the distribution block. 

   

The second schematic is a "junction point" that on my coach is found on the rear wall of the left rear air spring tank.  The left rear air spring tank is the one that is the most forward & sits above the transmission cooler with the double fans.  This is where Newell chose to join the front & rear suspension air system (red), front & rear house system (blue) and the front and rear brake system (black).  Newell provided two shut off valves that allows you to shut off either the red or blue systems or both.  There is no shut off for the air brake system. 

   

The "junction point" is very difficult to get a good picture of and get all the lines in it.  These are the best I came up with.

       


To understand where the air goes we'll look at how it works by providing "shop" air to a totally drained air system on each test. 

Test #1--Turn off both shut off valves and air is provided only to all three brake system air tanks, the brake dash gauge and the 3 gallon air tank in the first compartment on the right side.  ***Not all coaches will have this 3 gallon air tank!

Test #2--Open the "red" circuit shut off valve and leave the "blue" valve closed.  Air is now provided to all three brake air tanks, the brake dash air gauge, the 3 gallon air tank in compartment R-1, the front & rear 6 packs,  and rear air dryer.

Test #3--Open the "blue" circuit shut off valve and close the "red" shut off valve.  Air is now provided to the 3 gallon air tank in R-1, all three brake air tanks, both the brake & supply dash gauges, the 3 gallon air tank in the RR wheel well and the entire 12V air compressor air system.

Test #4--Open both the "red" & "blue" shut off valves and the entire coach receives air.

Hopefully this helps you understand how your system works and how each "circuit interrelates to each other......................................

Hello All:
We are trying do decide how to move our toys around with us as we travel the US.  My initial thought was to buy a 24 ft. stacker trailer  to carry my motorcycle - Ducati MultiStrada -  a Big Green Egg and some kind of car.  However, I have been told that a trailer is not worth the trouble and we would be better off with a motorcycle lift on the back of the coach and a towed car.
Can you share your thoughts and experience to help us make the right choice?  Thanks for your help.

This is the same exact solenoid that Newell sells.  

Part #: SMC VX3114-01N-6G1-B valve

Hi Everyone:

My name is David Sugg and my wife Lengki and I live in Cornelius, NC. along with our two dogs, who will be traveling with us.

We just purchased coach #1487 from Newell and we plan to travel North America beginning in November of this year.  We are total newbies to RV'ing but I have owned and driven Renegade Toterhomes with 48 ft. lift gate trailers for the last 10 years, so the driving part should not be a problem.  Everything else, however, is a different story.  Reading blogs and Guru posts has given me an appreciation of the challenges that we will face when we are on the road full time. I do feel fortunate that we purchased a Newell, as I don't think that there is a better built coach on the market, regardless of the price.

I want to say thank you in advance to those who answer our questions in the future, and hope to meet some of you in our travels.

An air solenoid is mounted below the air dryer in the engine side compartment (see photos)  Has two 1/4" black air lines and a red & black wire going to it.

Does any one know what its function is???

Gang,

This morning I am in the coach after having been away for a while.  I realized that my aquahot was not making hot water using the electric side.  Not a good thing!  (The diesel side works).

I thought to myself what would @"Trainer" (Rudy Leget) do.  I checked the fuses and bumped the relays but no joy.  In a fit of self doubt, I called Rudy.  It was so good to hear his voice.  He first had me check the little red overheat breaker inside the panel above the burner.  Sure enough, the red button was popped out.  I clicked it back in.  In a few minutes my hot water returned.

I have two take-aways from this experience....

1)  Rudy is THE MAN when it comes to aquahot.  He has some sort of sixth sense....When I said that I had my hand on a part, he said "Not that part, its the one to the left".  How did he know???!!!  His knowledge, friendly demeanor, and quick wit make him a joy to work with.   (Hint:  If you want your aquahot to really sing, give the music to Rudy).

2)  The Gurus are really a great bunch of guys / gals.  Whenever I am getting frustrated, I know there are a bunch of guys willing to take a call and set me on a success path.  

Thanks for all you do!

ps.  Happy New Year and safe travels y'all!

We have a 1997 Newell Coach and it appears that are top front amber clearance lights are causing a leak in the front cap. We have drips going down in front of the TV and have wet carpeting in front of the fuse panel by passenger seat.
We would like to replace these lights or at least get new gaskets for them.
I guess my husband said one light was full of water.
Chuck at Newell said that they get them from Truck-lite. I was wondering if anyone has ordered these and would have the correct part number for them.
Thanks!!

   

I couldn't wait till April 1 because of the outcome. 

My original concept was to post this as an install I did on the passenger side. I was going to explain how the co pilot was always helping me apply the brakes, so why not just make it easy for her. It would have been a simple process to tee into the supply and delivery brake lines to allow duplicate brake pedals. I was also going to observe how the coach now went into corners and exit ramps much slower than before. Go figure.

But, the outcome of this brake pedal change overrides the prank. 

As long as I have owned Newells, I have found the brakes hard to apply. Meaning it took a lot of leg force to apply the brakes. As a recovering engineer I did a lot of noodlin about that, and asked many of you if you had the same issue. Most said no. I finally figured out that it had a lot to do with the angle of my leg and the design of the brake pedal. I won't bore you with the vector diagrams and force calculations, but I sit high and close to the steering wheel, and that results in my brake foot pressing almost straight down on the brake pedal. A lot of the force from my foot is wasted because of the angle. If one sits further back or lower then the force is more in line with the direction of travel of the pedal. It's intuitive and the force vector analysis shows proves it. I wasn't going to have much more luck changing my short legs, short arms, long torso build than I will have growing hair. 

I also did the math for the standard floor mounted treadle, the math indicated that for my seating position I would gain almost a 30% mechanical advantage due to the angle of a floor mounted pedal. For the hardcore engineers, I did take measurements of the pivot points, angles, and moment arms for both the Newell horizontal mount pedal and a standard floor mount pedal in order to calculate force applied to pedal into force applied to the valve. The problem that stopped my pursuit was that the floor mount treadles mount the air valve underneath. That would have meant cutting a hole in the floor, rerouting all the brake lines, and wiring to install one. No go, with the first barrier being the floor is about six inches thick. That was the status for almost 7 years. 

Last fall I completely stumbled into a treadle valve assembly with horizontal mounting of the brake valve. I decided to take a chance on a $500 experiment. 

Holy Moly!!!!!!!

For me and me seating position it is the difference between driving an old car with drums without power brakes and a new car with power brakes and discs. I held my breath on the first drive after the install (Rhonda did too thinking it wouldn't stop) hoping I had not thrown the money away. I was blown away by the difference in reduction of force required to stop the coach. 

For the install I had to lengthen several of the air lines, and I left the air lines so that I could reinstall the original setup quickly in case my experiment didn't work. I have to rework the foot panel to fit the new pedal now. 

The math does not explain the difference completely. Brake pedal valves have different compensation ratios, in other words the amount of back pressure fed into the pedal compared to the pressure applied to the brakes. If there were no back pressure there would be no brake pedal feel. However I do not know the compensation ratio of the old unit or the new unit. 

I have a way of measuring the pressure in the brake line by plugging a gauge into the outlet for the toad brake. I wish that I had run a little trial with the old pedal before I removed it. Then I could have rerun the trial with the new pedal. I may enlist help from one with an M&G toad setup at Ruidoso to gather the data. 

If you get interested in this mod, the part number is Williams WM569A, and I sourced it from www.brakesystemsinc.com.  It is not in their catalog, so call and talk to an application engineer. They do show a horizontal treadle, but it is not dual circuit, show don't buy the wrong part. (Don't ask how I know this). I also could help with the air hose routing if you need it, since it took me a minute to understand how the ABS system was tied in. And in case you are wondering, the setup is FMVSS approved. 

I am one happy driver after the test drives.

Hello to all! I am soooo glad that i have found u guys and i figured it was time to introduce myself. Me and the wife bought our first Newell last October. Wasnt really looking for a coach but ran across a deal on this one that i couldnt pass up. I have learned so much about the coach from this site. Im still working on finding the coach #. Im sure i will have alot more question as time goes on. Thanks Aaron
