I too have this problem with no power to my keypad. Tried to diagnose. Have power to the control panel (12v) have power to the touchpad (12v) but the touch pad does not turn on. The only item I cannot seam to locate is an inline fuse from the control panel to the ignition wire?? I found a diagram that showed this but not sure if mine has it. I am assuming this inline fuse protects the unit from the signal telling the control board the engine is running. I took it to the shop before leaving town and Atwood instructed them to replace the touch pad which they did and it did not solve the problem. I left town with out operating levelegs. Any help is much appreciated.
