Recently, during a storm, an outdoor spotlight was broken in its socket, its internal wiring shorting out. The lights happen to be on a motion sensor, and in turn on switch, and a breaker at the panel.
Replacing the spotlight bulb, nothing worked, so I checked with a non-contact tester, no power in the socket. No breakers were tripped at the panel. So I pulled the switch; it looks like there is no power their, either! It seems like everything else that should have power does, but I haven't exhaustively checked every nearby outlet.
This is in Canada, and I know the house was just about entirely rewired ~10 years ago.
I'm at a loss how this is possible, but anyway. How can I find the fault?
