Title: Travel Light Issue
Post by: jor on September 10, 2016, 04:55:12 pm
I have an HWH issue. The coach levels fine and passes all the HWH Section 1 tests. However, it is displaying the following behavior: 1. The coach is level and the red air light is on (normal). I start the coach and hit the off button on the HWH pad. The travel light will not illuminate, the "level system" dash light is on and the beeper continues sounding. The coach appears to be at proper ride height. 2. I turn the HWH system back on and raise, lower, level and so on. Eventually, the travel light comes on and the beeper silences. I move the coach in and out of my driveway. The travel light comes on, goes out; the beeper, of course, keeps beeping when the travel light is off.
I had hoped to take off tomorrow but this is kind of show stopper. The manual seems to indicate that it's a pressure switch or a shorted wire on one of the manifolds or a bad control box. Anyone have any insight based on personal experience? Thanks. jor

Travel light off, dash light on, and beeper beeping all indicate low system air pressure.
The travel light should come on when ignition is on, HWH level system is off, and system air pressure is sufficient to open the NC (normally closed) system pressure switch on the rear 6-pack manifold. This pressure switch on our coaches is usually set to open at 80-85 psi. If you have the engine running, level system off, and air pressure is up to normal operating levels, then you should have a travel light.
I would start at the rear 6-pack pressure switch - remove the wires, clean the terminals and wire ends, reinstall. If that doesn't solve the malfunction, then the next time it happens (light won't come on), try disconnecting one of the wires from the pressure switch. If the travel light then comes on, I would replace the pressure switch. One of those two procedures should cure your problem...I hope.
Good luck!

I'll try that in the morning, Chuck. Thought I would also do the same to the pressure switch connections in the control box.
Question: Can you drive if the travel light is not illuminated (if coach is at travel height)? I've read that an off light does not necessarily mean that the travel valves are off. I need to get on the road. If I have to get parts from HWH I am going to have to cancel my trip. Thanks.
(Should mention that the system was at normal pressure (110#)) jor

Good question - I don't know because I've never tried it. I would guess there might be some interconnect between the "low air pressure warning" signal and the transmission, such that the tranny would not go into drive. But you said you were moving the coach with the travel light going on and off, so apparently that is not the case. If you are sure you are at normal travel height, your air pressure is otherwise completely normal, and the transmission operates normally, I would say go ahead and drive it. The warning beeper might drive you crazy, but some of them (like mine) have a little volume screw that can be used to silence the chirping.
If any other member sees any problem with you driving in this condition (i. e. no travel light), then hopefully they will speak up. You might PM Brett Wolfe and ask him about it - he is our highly-paid resident technical guru, after all. 8)

Jor,
Sounds like you have a bad pressure switch like Chuck has suggested. You can get them from most any parts store. To answer your other question is if you can make sure that the travel height is correct you can open the cover off the control computer and pull the fuse that feeds the travel solenoids (on your coach it should be #11) and keep your coach level manually with the push buttons. We have traveled from Carlsbad, Nm back home to East Texas like this.

When I bought the current Fortravel in S.C. last year I drove it all the way home with the travel system not working. After 5 miles of the tire rubbing under the DW's seat pulled over and manually raised the coach and drove the remaining 2400 mi. All I had to do was pull the fuse to the HWH and put it back in and all is well. I didn't belong to the Forum at the time of purchase so I didn't fix it until after I joined and started reading.

Here's the Nason catalog. If the thread is 1/8" NPT male, then it looks like your switch should be a SM-2B-85R/--, with the last two characters indicating the type of wire connection. However, your photo does not look like any of the switches in the catalog, so I don't know what you have...

Well, today I cleaned the connections on the three HWH pressure switches and for good measure, in the control box too. Had the rig up on the safety blocks while I was working under it. Anyhow, raised the coach and removed the blocks. Started it up and no travel light.
I dumped all the air but the coach remained pretty high. That I didn't expect. Maybe something else is going on. I fooled around with the pad arrows to put the coach out of level and re-levelled with no problem. Turn off the system but still no travel light.
Anyhow, tomorrow I'm going to do that other test with the control pad and the control box. I'm also going to call HWH regarding the pressure switches. Turns out the front two look similar to the ones Chuck posted. Maybe my rear switch has been replaced. Anyhow, no luck so far. jor

Often times, if a coach won't dump all the way something like a mud dauber nest is clogging an exhaust port in an HWH manifold. It doesn't typically happen to all 4 exhaust ports at the same time, though, usually just one corner.

Those two pressure switches on your front manifold look original and correct. According to the HWH manuals, Foretravel chose to supply their own pressure switches for the front manifolds - they wanted a lower pressure rating than the ones fitted by HWH. The exact switches used on the front are still available:
Stewart Warner-Stewart Warner - Hobbs Pressure Switch 10 psi Normally Closed... (http://www.partdeal.com/stewart-warner-hobbs-pressure-switch-10-psi-normally-closed-2-terminal-76578.html?zmam=74973193&zmas=1&zmac=4&zmap=77158416&gclid=CNf1r7Lwic8CFZaHaQodBwULVQ)
The switch normally found on the rear manifold was originally supplied by HWH. I suspect you are correct, and the one on your coach was replaced at some point. If the pressure rating corresponds to the part number you found on your switch, that would mean it does not open until 105-115 psi. That is way too high for this application. I am surprised you have not had more trouble with your "travel" light going on and off every time your air compressor cycles.

The two exhaust ports that need to be kept cleaned out are located in the middle of the manifold. In the front, they are kinda hidden under the pressure switches - in the rear they are actually easier to see, although usually covered in dirt and grease. Photo below is the front manifold:

Thanks, Chuck. Wish my manifolds looked like yours! Unlike my other rigs, this one spent its life up north and really shows it. I wonder if I can just get the same switch with an 80-85 psi rating for the back.
I called HWH first thing this morning. Get this. There is a four day waiting list to order parts. You have to wait for a call back. They suggest using their website but it's peppered with 404 errors. I called FT too and am waiting for a call back. FT parts department is good but they are wedded to an archaic phone setup. jor

Found one for $40 + shipping:
You're a wonder, Chuck. Well, I tried removing one of the wires from the rear switch (air at 110psi, ignition switch on). The travel light did not come on so I guess that eliminates the pressure switch. The link you sent me (from Barry Beam's site) with the alternate test says, "Unplug the CN100 connector from the control box..." Any idea what connector that is? Also, a little confusing as this test speaks of a master control light which we don't have. Thanks.
Another thing. I found a BIG air leak this morning. I don't think it would influence this issue as I did the test with both gauges reading 110psi.
The plot thickens. Coach running with no travel light, level system prompt on beeper beeping. Enable air button, press the raise button and after a couple of seconds, light off and no beeper and travel light on. Wait a minute, light and beeper back with travel light off. Press raise, no light no beeper and travel light on. Leveled coach, turned off leveling system and travel light on! jor

The "Master Control" light your referencing is the "Level System" indicator on the warning light strip on the dash, the same panel that shows low air pressure, check engine, etc. On ours, when the control box (HWH computer) failed, I was confused by that description. Turned out that the troubleshooting tree which says
Quote
"With the ignition switch on: a. The green "TRAVEL" light nor the master warning light is lit." AND "Whenever the ignition switch is "ON" one of these lights will be lit but never both at the same time. If neither light is on, check the power to the control box. The yellow wire in the power harness will have +12 volts with the ignition in the "ON" position. The red wire should have +12 volts with the ignition in any position. If the yellow wire has power replace the control box. If not, trace the yellow wire to its source."
This was the issue with our coach, and I chose to replace HWH computer. No problem since... If I read it correctly, you said that the "Level System" light was on. If so, that probably means your computer is not the issue. I hope that is the case, though the HWH computer can likely be repaired much cheaper than being replaced, there is no way to tell short of sending it in. Don

I've been looking at the manual schematics. Turns out that the text Don quoted is the same as in my manual so the Barry Beam text doesn't apply. Anyhow, after I get the leak fixed I'll return it to ride height and run the test for power at the box. I'm hoping it's not the box although I sent one in for repair a few years ago and it came back within a couple of weeks and it was relatively inexpensive. Thanks. jor

I haven't rebuild my rear 6-pack yet - waiting for cooler weather - so I have never really paid any attention to the pressure switch back there. This thread got me curious, so I crawled under this morning and cleaned the switch off so I could get a good look at it. Guess what? It looks exactly like the one in your photo! There is no label or i.d. info of any kind affixed to my switch, so I can't say if it is the same brand/model/rating as yours. BUT, I would say this suggests that your switch may, indeed, be original equipment. If you ever hear back from HWH, they should be able to verify that fact.
It would be pretty easy to pull your pressure switch off and check it's function. Get a 1/8" or 1/4" (whichever matches your pressure switch thread) NPT female "T". They have them at Lowe's and Home Depot. Screw the pressure switch in one end, put a cheap pressure gauge (also available at Lowe's/HD) in the other end, and a quick connect air fitting in the 3rd hole. With a multimeter, check the continuity across the contacts as you slowly add air pressure. Meter should beep (closed circuit) until the opening pressure of the switch is reached, then silence. Note the pressure.
I have no idea what the CN100 connector is...never had to mess with our HWH brain box (knock on wood).
Where was the big air leak?
Title: Re: Travel Light Issue
Post by: jor on September 12, 2016, 03:18:24 pm
OK, here's where I'm at. I fixed the big air leak so at least I won't have to worry about that. Anyhow, when I got it off the blocks I leveled it. No problem. However, when I turned off the HWH, the dash light (now known to be the master warning light) came back on and, of course, no travel light. I checked the air bags and the two front left were deflated. I turned the HWH back on and manually raised the coach. The master light went out and the travel light came on. This appears to be the symptom that should lead to a solution.
The manual says in this instance, go to Section 7. That's where I'm at now. jor
Title: Re: Travel Light Issue
Post by: jor on September 12, 2016, 04:16:55 pm
OK. Did the Section 7 diagnostics. I have 12v at the control box for both Travel solenoids. This indicates the problem is a bad solenoid. I can raise, lower and level but the front lefts won't inflate automatically. That is, they won't return to travel mode.
Now, I'm back to an earlier post regarding whether I can drive it like this. Need to re-read those suggestions. If I raise the front left manually, the travel light comes on and all appears well. BTW, I am sure this is the longest thread I've ever initiated! jor

I'm ordering solenoids and hopefully pressure switches too from Motorhomes which will be delivered in Oregon. Then, when everyone is sitting around drinking wine and eating cheese, I'll be installing those parts (provided we make it, of course). Thanks to all for the great advice. jor

I drove the coach after doing my best eyeball ride height measurement (while stopped at a relatively level spot), and although nerve racking because I didn't know what the result would be, didn't have any problem. We drove a total of about 300 miles all told. I stopped several times to check the ride height, but it seemed to stay where I put it. It did seem not to track as well, but I attributed that to there being no dynamic adjustment of ride height in response to changing road conditions. Don

Post by: wolfe10 on September 12, 2016, 05:18:43 pm
Make a ride height checker to allow you to quickly check while on the road. Just be sure to park on a level place to check.
I use a scrap of wood, then drill and install two long nails 8.5" center to center. The 8.5" dimension is from the top of the top mounting plate to the bottom of the bottom mounting plate. This is easier to measure than the 8" for bag itself (plates are 1/4" thick).
Remember, there are two ride height valves in back, only the one in front. So, any side to side adjustment needs to be made first (i.e. the rear). Then (ya, with everything working as it should) the "average" of the fronts should be the same 8.5". So, if left front is heavier than right front, you might have 8.25" on left front and 8.75 on right front (though that is probably an exaggeration unless you have a very heavy rock collection on the left side)..

Just about out of ideas. Today I intended to get it at ride height and pull the #11 fuse. Ride height is no problem on the back as it is just about right without adjustment. The problem is with the front. The coach will hold air in all bags all night long but as soon as I start the engine (with the HWH off) the left front bags immediately deflate completely. I tried to get it reasonably close manually after pulling the fuse but I can't dump the front bags completely; the right two deflate partially but not all the way. I can raise the front and the travel light comes on but then the front is way high. Can't see how I can drive it like this.
Question: I've seen photos of bags and know that the actual air bag is inside the bladder we see. Here's the question. If the outside bladder is soft (can push it in easily with a finger) is the inner bag partially inflated?
Have a call into Triana and Keith at MOT. jor

Jor, Unless you are on level ground you can't get both sides on the front down all the way. As soon as the first front side bottoms out that 10psi switch will take power off the other side dump solenoid to stop that side from continuing down and twisting the coach. That's what the 10psi switches are there for.
Title: Re: Travel Light Issue
Post by: jor on September 13, 2016, 01:57:15 pm
Thanks, John. Understood. The ground in my driveway is not level but I drove the coach up onto a couple of 2x10s to get close to level. The problem is that as soon as I turn the ignition on those two front lefts lose all their air. Just can't figure out how to get it close to ride height so I can pull the fuse. jor
Title: Re: Travel Light Issue
Post by: John Duld on September 13, 2016, 02:40:01 pm
Jor, Can you tell where the air comes out? Is it coming out of the vent by the dump valve in the six pack (dump solenoid)or out through the (travel solenoid)ride height control valve? How are you getting air in those bags? Can you raise the front with the aux pump?
Title: Re: Travel Light Issue
Post by: John Morales on September 13, 2016, 03:21:06 pm
I have s similar issue with my coach. When starting at 110 psi on gauges, level switch off. The front will rise but the rear will not come up to travel mode. After raising the coach manually the travel light will come on. I just didn't know if it was the ride height valves or the pressure switch in the rear. After following this conversation I think I will start with the pressure switch. The funny thing is once I get it up I can dump all the air start the coach and it will go into travel mode with no problem. I do this many times and it works beautiful. I let it sit for a few days and I'm back to the same problem. Could the pressure switch be getting stuck?
Title: Re: Travel Light Issue
Post by: jor on September 13, 2016, 03:27:05 pm
John, I think your comment re level ground is the answer for getting it close to ride height. My driveway is large gravel and very uneven. I drove the coach up a little higher and raised it manually and turned it off. Then I pulled the fuse and started adjusting the front down. Ended up uneven side to side but much closer and the left air bags are inflated. Then I adjusted the back manually with pretty much the same results. I'm thinking I could drive it to a level parking lot and do the manual adjust without the fuse and then drive on. What do you think? Thanks.
Re air exit. I am not sure. It's not a large volume and I can ONLY hear it when the ignition switch is ON. jor
PS: Travel light is on.

I guess if it was me and I didn't have to go too far I would do it if I didn't have any other option. Go easy over any driveway entrances and hit them square if you can. If you have it fairly close to even it shouldn't be a problem. The worst thing you can do is break a windshield !😬

Too far may be in the eyes of the doer. My plan is to get out of here (rough, dirt road, cattle guard on a hill - probably the worst conditions for this situation. I'm just going to go dead slow and when I hit the pavement, head for a big parking lot. As far as distance, we plan on going 1,200 miles. I'll check the height frequently. I am making an appointment with Quality Coach Services in Eugene as they are familiar with HWH air systems and Foretravels. I may ship them a couple solenoids & valves along with the pressure switches as they are all available at Foretravel. Anyhow, that's the plan. Thanks for all of your valuable input. jor

Gran Vention going on. May effect FOT call back times. Call HWH and follow prompts to set up a service appt. tell your story to really nice lady who sets up appointments, suspect she can get a human in line for you

UPDATE Took the 270 to a reasonably flat area and jiggered around the ups and downs and ended up not far off ride heigh (HWH travel fuse pulled). Took off and checked all bags each time we stopped. No change. Made 500 miles. Also, I did not note any difference in handling so... so far so good. Well, the speedometer went tango uniform but the GPS gives us mph (sort of a poor man's VMS!)
UPDATE 2: Another 400 miles without incident (except a frequent dash light and weak beeper alarm unrelated to the level issue). jor

We have been driving for 2 hours and everything was going great. Now all of a sudden the Leveling System light has come on and we are getting a warning beeping. What should we do? Pressures are all normal. Where is the pressure switch. Paul

What is your coach? Does it have an HWH reset switch?
Title: Re: Travel Light Issue
Post by: OSIN on September 20, 2018, 07:35:07 pm
2003 U295 40' There is a reset switch. The beep and light go off for awhile and then come back on for awhile. The pressure is going between 100 and 110#

Were you driving or stopped when it happened? Have you tried stopping and setting the brake and killing the coach then starting back up?

We are driving now. We will stop at the next opportunity and try that.

It could be a slide locked indicator switch sending a bad signal. Try to extend and retract your slides and make sure that the locks engage.

Our HWH pressure switch triggering an alarm is on the 6-pack and when the switch wiring gets wet from rain splashing up on 6-pack, the switch shorts out and triggers a false alarm.
BTW, would be nice for the signature to have coach info, instead of first guessing until it is offered.

Update: With help from Jerry (Foretravel Owner) who me met in a Casino parking lot, we were able to pull fuse 11, the dash indicator/sounder went off, then after seeing it was clear reinstalled Fuse 11.
We were able to drive another 250 Miles...When we hit a bumpy section of the road the dash indicator/sounder was on again, and about 10 minutes later, (smooth road) the lamp extinguished, all normal again.
Headed under the coach when it cools down to look for loose connections etc.

All,
Today's update.
We drove another 350 miles or so, all good again until we hit bumpy roads, then the alarm went on again, and after we hit some decent roads it stopped?
I went under the bus to inspect the rear manifold for a loose wire etc....Where is this manifold located? If anyone knows where I can obtain a location/build sheet for a 2003 U295 WTFS that would be great. Looking for components of major systems, both electrical and mechanical/pneumatic.
Right now I'm stumped but we should be able to make it to our Oklahoma destination. I think we'll probably need to make a trip to FOT after we complete our work here in OK. Assuming I can't figure it out here

It should be mounted on the frame rail just behind the right rear wheels. It should be visible if you open the basement door behind your rear tires on that side. It is somewhat hid behind the ride height valve.

Another day on the road, another failure...LOL
It seems to only act up when we hit hard bumps, sometimes it corrects itself and others not. Today was fine except a few bumps which corrected itself, then this happened...LOL
We pulled in to park for the night where we will be for 2 weeks in Oklahoma, leveled the coach, put the slide out, and the damn light/sounder would not shut off...Tried putting the slide in and then out again...NADA, pulled fuse 11 again, NADA... This time it still stayed on, would not go into drive mode correctly (flashing #6) etc....It's really frustrating, but hopefully I'll be able to find a way to drive out of here in 2 weeks.
Still better than a winnebago, but I want to call her bad names now

In this latest instance, was your HWH panel "ON" or "OFF"? If this alarm is being triggered by the HWH pressure switch on rear 6-pack manifold, then it should be silent when the HWH panel is turned off. If the HWH panel is "OFF", and you still have the alarm, then it is probably not being caused by faulty pressure switch (or pressure switch wiring).

Check room slide in or out sensors, check bedroom slide ( may be under bed if you have an east west bedroom slide) Also check Barry Beam site for photo's. Also you have around 6 air pressure sensors on the air bags to tell HWH System bags are inflated. Good Luck!

6 air pressure sensors? On the air bags? Where are they located, exactly? Do you have a photo of one of them?
Title: Re: Travel Light Issue

You can go to HWH Corp. and under Foretravel specific manuals and parts. You go to M-2656 on pages 20-25 you will see air pressure sensing units that are on the 6 pack manifolds. This is on the HWH 2000 leveling system. Or on Barry's site search for air pressure switches or under RV technical help you can go down to Air System and click on HWH Air Leveling System Explained.

Ellen & David,
I have a good understanding of how the HWH leveling system works. The reason I commented on your post was because you mentioned some features of which I was not aware, namely:
"you have around 6 air pressure sensors.......on the air bags.....to tell HWH System bags are inflated."
I was curious about this statement, because all the HWH leveling systems I have seen only have 3 air pressure switches - 2 in the front and one in the rear. They are not located on the air bags - they are located on the 6-pack manifolds. And, the switches have no way of knowing whether or not the air bags are inflated. They only know what the pressure is in the manifold to which they are attached.
Reading your post, I thought the HWH Series 2000 system might have some features that differed from the earlier systems. That is why I asked. After looking at the manual, as you suggested, I see the 2000 Series is basically the same as earlier iterations, but there are differences. One big difference is the addition of two "extra" pressure switches on the rear 6-pack manifold. Plus, if the coach has a tag axle, then there are 2 more pressure switches on the tag manifold, giving you a possible grand total of 7!
Makes me glad the leveling system on our old coach is so (relatively) simple. 8)

I looked, but I really don't know what I'm looking for...lol and I'll be dammed if I can locate any schematics/locations/pictures for our coach. I've been working all week so I've had have limited time....I had to tear apart the wet bay to fix a bad Water Check valve.
I'll look again tomorrow (Saturday). We have to leave in a week and somehow this thing has to move...LOL I'll just need to find a way to bypass things...Man I don't like being stranded

Thanks, That will give me some reading to do. Someone mentioned slide switches could be a problem. Do you know where these things are located?
Thanks, Paul

There are limit switches over the top of the main slide out and may have limit switches on top of the bedroom slide and also maybe on the bottom of the slide under the closet if you have the closet slide out.
