Hi......from an “old man”......we are never too old to learn new things and owning an RV is a great (occasionally frustrating) way to do that. Even old men wish RV troubles could be cured with a “one button push”. You may be able to do that with this trouble but sometimes the hardest part is finding the failed device to reset (if it is even resettable). The generator starter motor is typically 12VDC powered off the coach (house) batteries through a 100 Amp DC circuit breaker. That cct breaker (if open) may also cause your lack of coach power too depending on how Thor wires Chateaus. Usually that 100 Amp breaker is located close to the coach batteries mounted on the wall. Since I am not familiar with your coach maybe someone who owns your coach will chime in as to locations of some likely breakers. The other thing you could try is carefully follow the positive battery cable and see if it wires directly to this 100 Amp breaker. If it is close you might see a yellow arm popped out of the black body of the breaker. Push in the flag to try to reset. It might be some other color too. If your batteries are showing fully charged once you reset this breaker you should be able to start your generator at least.......
