HWH panel dead, with Key on no indicator lights on the controller.

Monaco, Executive, 2005. It is air level with the airbags only, no hyd. But the airbags won't inflate until there is power on this unit for travel. So, I am stranded at this time. I cannot get the 12Vdc power to any of the HWH boxes? Its like it doesn't know the key is on. So, on this Monoco RV, is there is solenoid or relay that the ignition key activates or does the power go straight from the key switch to the circuit boards in the drivers side forward electrical compartment? I have checked and changed both fuses in that panel, but still the same. I crawled under the control boxes between the frame and none of those LED's are illuminated. So, I am thinking it is something common between the panel controller and the main control boxes underneath? Previous owner had intermittent issues but I'm learning he never found the root cause. But now it is rubbing the tires on the frame, and I can't drive it. Is there a solenoid or valve I can bypass to bring up the ride height and drive it so a service center? The control panel is completely dead whereas on the drive home last week something was always lit when the key was on. The hidden fuse listed on that panel saying Hidden fuses, I have not found? Where is it?

HWH uses a master solenoid that is a continuous running device and another that is a momentary run for the active air.

Locating them will be a struggle without another owner with similar coach to help.

Did you find the hidden fuse in the armrest that is on the label you showed? Also, you can air up the suspension by hooking up to the fitting in the generator bay with compressed air. I think you may have a hard time finding a shop that is knowledgeable on the system so question them thoroughly before committing to a shop
