I have a 2007 Contessa with air only Valid levelers. I have had a nightmare with the electrical systems since having been hit by lightening. I think I have the 120 volt working properly now, but now to the 12 volt. My generator will not go out and the valid keyboard is dead. Everything on the panel under the window(?) where the keyboard is, seems to have power. I looked for blown fuses in the electrical cabinet below the drivers seat and didn't see any that appear blown. Can someone help me by giving me the fuse number of the fuse for the Valid and the fuse for the generator out? Thank you ahead of time.

I had a 2008 Contessa, and I saved a screenshot of an old post here on the forum where another owner defined the Valid air leveling fuse as F20.

F20 is the Valid Air compressor fuse. F46 should power the controller/keypad.
Have you checked the circuit breaker on the generator?

I can't get the generator to come out, might be a bad fuse there as well. I changed fuse #20 and nothing changed.

Al,
Sounds like you may have lost 12v. Couple of items to check.. On the large PC board in the front electrical bay there are 3 large terminals (lugs) on the right side as you are looking at the board. The top one is House battery voltage, the middle is Chassis battery voltage and the bottom on is Gnd. Check to see if you have voltage at the top 2. A drawing of the layout is on sheet 2 of of the 07 Contessa wiring diagrams in Coach Assist.
If you don't have voltage at one or both of the terminals check for a blown ANL fuse(s) in the rear run box (rear bay, pass side). Diagram is on pg 18 of 07 Contessa wiring diagrams.
if you have voltage F42 is for the front hydraulics so it should run the generator slide. (uses chassis voltage).

Thank you guys, I changed fuse F 46 and the keyboard came right up. Thank you so much. Now ... after the keyboard came up, I attempted to get the generator to move out and ... it moved and works well in and out. Now I know the only thing that heals itself is the human body so I assume whatever was causing the generator to not move is still an issue and will pop up again.
Thanks again for your help, I really appreciate it.
