Electrical problems are a pain! I feel for you.
Try this guy. He is in Fountain Valley. I have not used him, but a friend of mine, with a Beaver, had some work done, including replacing his refrigerator. Speaks highly about Bret. When I was in Huntington Beach in December, I had a problem and called Bret. I was leaving the area,and we could not get together. But, he helped me figure it out myself, and I was able to leave the next day.
He is mobile, so he will come to you.

There is a web page that I have used to find repair facilities when I travel and need help. Like all of these sights, you have to be careful and ask a lot of questions. Pick the state that you are in, and it will show you shops that people have rated, both good and bad.
