Re: Travel Mode / Ride Height Problem Reply #26 – June 23, 2020, 11:22:55 am Ralph,If you are getting the green travel light then power is being sent by the computer ( sounds like that's working )to hold all the travel solenoids open so the ride height control valves can set the travel height. The green light only tells you the power is being sent to all travel solenoids . It doesn't tell you if they have opened. So, from your original post it looks like a right rear travel solenoid or ride height control valve problem. To eliminate one of them,block the coach and with a meter confirm 12 volts is going to that solenoid when the green travel light is on. If it is you could swap the rear travel solenoids. If the problem follows the valve you found it. If it doesn't I would start looking at the ride height control valve linkage. With the coach at travel height on level ground the long arm on the control valve should be parallel to the ground. Probably easier to check that before swapping valves. Quote Selected 2 Likes

Re: Travel Mode / Ride Height Problem Reply #30 – June 23, 2020, 01:00:52 pm Thanks everybody I put the fuse in and it lower itself onto the blocks. Thank you Ralph for opening this post as I got this handled.Now I can back to wiring up the Jake brake. Quote Selected 2 Likes
Re: Travel Mode / Ride Height Problem Reply #31 – June 23, 2020, 04:22:22 pm Glad you found your problem oldguy, I was betting on the travel fuse.......I've got a plate full of stuff going on right now and it will be a few more days before I have time to check into the problem I'm having. I'm quite sure I have a travel solenoid with a bad coil....but we'll see. Quote Selected
Re: Travel Mode / Ride Height Problem Reply #32 – July 04, 2020, 12:49:30 pm To close out this thread, I finally had time to tear into my leveling problem in travel mode....found I did have an open coil on the RF travel solenoid. I think I'll carry a couple of spares as the travel coils are energized and quite warm any time the key is on and HWH system is off (think driving time here). After 25 years I'm not too surprised that one "burned out." Quote Selected 5 Likes

Re: Travel Mode / Ride Height Problem Reply #34 – July 05, 2020, 10:44:01 am Yesterday I went to move the coach. First I had to raise it to pull the blocks. Shut the engine down pulled the blocks and restarted theengine. The travel light didn't come on so I pushed the dump valve and the travel light came on, but it wouldn't go down on it's own.I didn't have time to check the fuse again so I manually lowered it to do the move. I will check the fuse this morning. Probably wasn't as simple as a blown fuse, now I will have to find what has blown it. Quote Selected
Re: Travel Mode / Ride Height Problem Reply #35 – July 05, 2020, 10:57:54 am Travel light only means you have air pressure. Quote Selected 1 Likes
Re: Travel Mode / Ride Height Problem Reply #36 – July 05, 2020, 11:23:46 pm Thanks I watch the travel light today and it came on when there was enough air. Fuse looked good but haven't check it with a test light. I will look into tomorrow, but it think I will be looking for more than just a fuse. Quote Selected
Re: Travel Mode / Ride Height Problem Reply #37 – July 06, 2020, 11:20:56 pm I went and turned the key on to test the fuse with a test light and when I went out side the coach was lowering itself. When I changed the fuse last week it did the same thing and what I realized was both times the air pressure was down below 50 lbs.It seems it isn't working when the air pressure is up. Will start working on it soon. Quote Selected
