No, it is in the correct place. Or more correctly, it is in the place shown on the diagram.
I spoke with a knowledgeable guy at Standard Horizon. He said that the problem was that I probably did not have a true ground for the power. Since I don't know where the power is actually coming from, I chose to rewire the system from a 12 volt panel that had a spare breaker.
All seemed to work
. I could even do a radio check without a problem. But when I did a second radio check the fuse blew.
I will call Standard Horizon on Monday and talk with the same guy. Hopefully he will suggest what to try next.
