When I first checked the red led it just flashed and I only could see the approximate location. After my wife held the switch on, the red led light stayed on and I was able to pinpoint the exact location. I am going to try and find a new 1610-92 circuit breaker and replace the one that could be bad. I am not sure how this device works because it looks more like a fuse and plugs in just like a fuse.
