Electrical help for my Brother in Law with SOB
My BIL bought a new Thor Quantum Class C, PDI went well but since he's been home, the shore power keeps blowing the house GFI instantly. He's tried multiple outlets on his house to see if there is a change and it keeps doing it. So essentially, there is no shore power. Worked at the dealer a few days ago. I was trying to help him over the phone last night, he was saying he can run everything on the generator, and he also has an inverter that's working but obviously killing the batteries after a while. From what I can gather he's using the 30a cord stepped down to 15a adapter and extension cord. He wasn't trying to run any big appliances on the 15a, just outlets and TV. Other than checking for breakers tripped or blown fuses, what else should I look for? I'm heading over today there to try and help out. We have a trip in 5 days so we want to get it working on shore power. Thanks.
