Rewiring

I have been waiting six months for this. He called yesterday and said he was free for a few days. I called right back and he is in my house now!!! I can get the bathroom fan wired in finally; it was installed by me last October. He is trying to finger out why I have been having voltage drops in the house. My TV picture would just blackout for no reason and I would have to turn it off and on before the picture would come back. I tell you later, when I learn more.
