You may have melted the wiring inside the plug on the cord. Take a look at it and see if there is discoloration around the prongs or the rubber looks like it may have slightly melted around them. IF SO, you will need to cut that one off and install a new plug. Camco makes some good ones for this. It might be inside the panel, but that would be rare. Avoid electric heaters as they tend to damage the cord from pulling too much amperage! Hope that proves helpful here. Please get back to me if you need more as all follow ups are included in our fee.

Cords test ok got elect to the junction box where the cord connects to the coach
Expert:  Randall replied 1 year ago.

How did you test the cord? You would have to disconnect it from the load center and ohm out the leads to be sure none were melted together. Is that what you did?

There's a orange 10 gage where going to breaker panel where not shore where it originates at
Expert:  Randall replied 1 year ago.

It might be in the transfer switch..........that is where the genset supply comes together with the shore cord. So what isn't working now? Or is it just that you have 120 VAC in the ground lead? It appears that you don't have a good connection on the white neutral lead. Did you check that in the load center where it attaches to the neutral bar?

Or perhaps you developed a problem at the power source..........check that.
