HWH Travel Fuse

June 29, 2023, 10:32:26 pm

After doing quite a bit of work recently on the Level System, I have a question about the Travel Fuse in the Control Box.
I know you can pull the fuse (I believe #11), manually set your air bags at 8.5" and "fool" the system into thinking you're in Travel Mode. Also, I've heard of people doing this to raise the coach and drive slowly for a short distance to clear a steep driveway or other similar obstacle.

My question is:
Could a switch be installed on this fuse circuit to allow you to manually override it from the drivers seat just as if you removed the fuse?
This would allow you to switch that circuit off (just like you pulled the fuse), drive up the driveway, then switch back on and back to normal.
I realize the potential problems that could arise if you forgot to turn it back on and drive long distances, but other than that does anyone see an issue?

As far a raising the coach for a drive way just push and hold the raise button on the touch pad. I do it all the time to get on my lot in Yuma

Yes you could put a switch in. You would need to somewhere cut into the circuit and run two
wires up to a switch and the dash. I have thought about doing that and then thought it was
to much of a hassle. If I ever do it I would put a light so I new the travel mode was off. The nice
thing about the switch it would be easy to control the height.

A switch may come in "handy" or convenient sometimes, but if you travel too far or too fast in the "raised position ...... bad things could happen. 😑

I could see myself doing just that. 🙄

I put the switch in and mounted it under the dash right behind the control pad. It became too much of a nuisance so I just use the raise button now.

So quietly a couple years ago after that u320 got hung up down in the Phoenix area I  made a work around to operate my coach off-road with the travel circuit off. I did a workaround on the parking brake switch circuit to fool the computer into thinking the parking brake is electrically set when released. I also added front axle travel lights to indicate full up travel on either side of the front axle to help prevent stress on the coach. The Active travel mode is for flat roads and will do evel things when off road. This mod has worked well for me but im hesitant to promote its use due to the fact you can put your coach into a total loss condition. For me it removes adding additional stresses by the active management doing its job.  With the front axle indication I can manually roll the coach to unload stress in a certain section of road. Once cleared and back on fairly level road I turn the bypass off allow active management to relevel and turn it back off till im back on the road. Basically it just makes the suspension stupid like a car. Also enables operator too make stupid mistakes equally easy. This is not for most operators, but extremely effective for a limited few. Also the control l switch has a bright Red light illuminated when engaged

I used Scott's method just never added the warning light. The switch is still under the dash but just not used.

Bruce, I do use the push and hold method now. I would like to add the switch just to make it a little easier. Where I live in Colorado, everything is steep and winding to back into my garage. Holding the button while backing down my steep winding driveway, while making sure to clear the trees and keep the brakes on with the dang beeper going constantly can get a little stressful sometimes. (Probably about a Pucker Factor of at least a 6)
A switch will give me just one less thing to hold onto.

I will definitely add a very bright warning light when it's off.

I had full control at all times in my 2001. The raise button was latching and nothing stopped me from moving forward with it in raise mode. I could  move with the slide out too, regardless of if the override switch was on...seemed to be in override permanently. I had my computer gone through when I was at HWH expecting a rebuild and they told me everything worked as expected and that it didn't need it. No one really knew much about the nuances of the 680 series though so I quit trying to guess what was "correct" behavior.

Mark I would already have put the switch in if I had to use it like you do. I was thinking
about it if I went north again, so I could get on and off the ferry at Dawson City and
wouldn't have to disconnect the toad and hitch. I haven't needed to raise the coach
yet and if I do I will put it in.
