Just finished a cold snap so I started my rig and my generator. Everything ran great but get this....for some reason the 120 outlet above the windshield now has no power. All other outlets are working and no breakers are tripped. What the hell gives?? Any ideas? It worked fine until I starteded the rig and generator?? Thank you, Lee

Is the 120 volt outlet above the windshield previously used for your TV? Some will not work with the chassis engine running.

More than likely, Ron's answer is correct. Please come back and let us know if it is or not.

Well guys yes the power came back but it took about 20 minutes. Does that sound ok?

Remember there is two sides to a circuit, so before you think there is no power there, there might be power there but no return.

Put one lead of your meter into the narrow slot, and the other end onto a known good ground. You might have 120 right there. If you do, you have to look at the neutral side of your wiring.

Did you shut the engine off, or did it just magically come back on? If the outlet in question is in the cabinet over the driver, and it is brown, or black in color, it has a 12 volt relay that opens one side of the 120 volt, when the engine is running. If it was sometime after the engine was shut off, the relay may be sticking in the open position. This outlet box has 120 volt power anytime you are plugged into shore power, or the generator is running, even if the engine is running, so be carful if you decide to open the outlet, with power.
