Adrian, there is a huge A HA in your posts that kind of negate the data.

You have LEVEL and TRAVEL backwards in your understanding of how the system works.

LEVEL Mode - used for leveling the coach when parked. No solenoids are activated with key on or off, Raise and Lower solenoids activate when raise or lower buttons are pushed on the HWH panel or the ALL raise or ALL lower button is pressed.

TRAVEL mode- When the key is on and the TRAVEL button is pressed the travel solenoids will be energized. Even if the coach is left in LEVEL mode accidentally, the HWH brain will activate TRAVEL mode if the coach exceeds 5 mph. The travel solenoids are never energized with the key off.

The best I can tell is your solenoids are miswired. You can make no progress on ride height until that is corrected.


I have no confidence the labeling is correct. Let’s start from scratch now that you understand the difference between LEVEL and TRAVEL.

Raise the coach best you can. Support the front end.
Disconnect ALL of the solenoid wiring.

The travel solenoids are the two closest to the firewall, or in other words the end of the manifold bolted to the coach.

Turn the key on, the engine does not have to be running, and using a voltmeter, not a test light (you and I have been there, done that) find the two connections front and the two connections back that are providing 12Volts. Plug those connections into the travel solenoids, it does not matter on these if it’s top or bottom since both will be energized any time you are in travel mode.

The next steps will require a helper and careful focus. Follow the instructions exactly.
Key on, engine off.
Press the LEVEL button.
Press the Left down button.
Find the connector in the front that is energized.
Plug that connector into the center solenoid on the top.

Repeat this step exactly for the rear.

Press the Right down button
Find the connector that is energized.
Plug that connector into the bottom center solenoid.

Repeat those steps for the rear.

Press the left up button.
Find the energized connector.
Plug it into the top solenoid furthest away from the firewall. This will also be the end of the manifold with the 3/8 air hose entering.

Repeat for the rear.

You should only have one disconnected plug at each six pack now and one disconnected solenoid.
Connect them.

Remove your jacks

Crank the coach.
Put into LEVEL mode.
Press the ALL down button until the coach lowers.
Engine still running.
Press the TRAVEL button and wait.
Give it five minutes.
Turn off the coach and measure the ride heights.

Report back before going any further with adjustments please.
