Bob...Instead of calling the electrician on the phone, why don't you place a call to the local liscening board and go after this guy? With work like that I can promise you he wins more bids than you and the other honest electricians in the area. I would call this "electrician" and ask him, politley, about how he circuited something that you can't track down, get him to admit to the installation and then go after him.
