Wiring Disaster

I recently overloaded my system. Afterwards, the generator would power on but my outlets, roof AC, and microwave had stop working. I took my RV to a “specialist” and it was a big mistake. I quickly realized that this mechanic didn’t know what he was doing. Since the generator was running, but not providing power he said he had to change the 12v 120 White-Rogers solenoid, and a 40 amp circuit breaker. While I was waiting I heard him scream. He stumbled out the RV and said he shocked himself. I asked him if he disconnected both batteries and he said no, only the house battery. He then said I didn’t have to pay him and he didn’t feel comfortable touching the RV again because he was badly shocked. When I got back into the RV I noticed wires incorrectly hooked up and my generator would not start. From a picture that I had took months earlier, I was able to figure out where some of the wires went, but there are three wires I am unsure about. I have tried a few combinations but I have not had much luck getting the generator to start. The generator lights up but now it trips the breakers every time I try to start it. Everything else works in the house part. I have not been able to find any house battery wiring diagrams that explain what goes into each circuit breaker.

X2 Drew. I'd be inclined to get an experienced RV repair preson who is familiar with your rig. Many electricians are not familiar with either RV 12V DC or even RV AC systems just like many RV techinicans aren't familiar with AC.

You don't have to pay him - REALLY??? I'd be looking to the pros and cons of HIM PAYING all of your repair costs. Just in case start a log and pictures.

Assuming these are breakers for the 120V AC system, you plainly have some sort of a short circuit there, such as a miswired transfer switch or (if you have to plug the shore power cord into a generator socket) a miswired generator socket, and perhaps some other AC wiring problems as well.

Frankly, I don't think this is something that is practical to troubleshoot and diagnose safely over an internet discussion forum. I very strongly suggest you find an electrician or at least someone who is very well versed in AC wiring to help you out. It would be well to double-check that the AC ground wiring is intact and not somehow improperly interconnected with the hot or neutral lines.
