HWH and transmission pad lights

I have not been in the Foretravel for about 2+ weeks. The last time I was in it there was a break in the weather, it was warm, so I started it and the generator and let them run for about 1/2 hour. The coach air supply built up and the coach leveled. I turned the engine off and left. I must have forgot to turn off the leveling system.

Tonight I went to retrieve something out of the coach and noticed the HWH control panel lit showing ON (red lights) and with the rear amber light on indicating it was low in the rear. The air gauge read zero air. I could not turn the panel off when I turned the ignition switch to ACCESSORY. When I turned the ignition to off the lights stayed on. I removed the fuse link for the aux compressor, it felt a bit warm, I fear it must have been trying to level the coach for some time now.
I also noticed that the control panel for the Allison was also illuminated. The ignition switch is off. I don't seem to remember seeing the pad lit up when the ignition was off in the past.

Is this normal? if not what do you think I should check.

Lon and Cheryl,
I don't have a HWH leveling system but I'll share a problem I had with the Allison pad being illuminated when the ignition was off.  Turned out to be a oil pressure switch on the engine.  Switch was stuck "ON" (conducting between both terminals) even though engine was off (ignition off).  This is a switch added by Foretravel that's mounted on a 1/8"NPT TEE with the oil pressure dash gauge .  I think they can be found easily at auto parts stores (or Foretravel parts) and are not expensive.  I replaced mine with a 5 psi switch knowing that 5 psi was the minimum engine oil pressure when it's idling.  This switch also supplies power to the engine hour meter so an easy check is it see if the hour meter is running even though the engine is not.  If so, you'll need to leave the hour meter disconnected for about 2 weeks of driving to get back in sync ! (if you even care about it)
This wasn't where I purchased mine (can't remember where) but I think it's equivalent to p/n PS113 on this page: Oil Pressure Switch Sensor Specifications search  I can't tell you for sure if this one would work for you engine
Hope this helps.
