Once again, it looks like a winged wire connector loosen and created an arc in the box which fried the connection of the generator and the ATS. Went to Lowes to get another junction box and parts. While there I asked if I could use butt connectors instead of using winged wire connectors and was told that would work too so that is what I did. Please check your electrical connections on a regular basis...dropping the mic!!!

Dino,
The same thing happened to us on our 2018 Hurricane 29M, I was running the generator and I could smell something burning, stopped the generator and the smell continued to get worse. After some searching I looked under the rear of the RV and saw smoke and flames coming from the junction box that connects the wiring leaving the generator to the wires going into the transfer switch...had I not caught this in time I'm sure the motorhome would have burnt to the ground.
The problem I found wasn't with the wire nuts, instead it appeared that the insulation on one of the hot wire was damaged at the point where the wire had been opened, this allowed arcing to occur that was sufficient to completely melt the junction box and start the fire.
Keep in mind that this is very close to the 80 gallon fuel tank...would make for a spectacular fire.
