I have a string of outlets in a finished bedroom in the basement that is dead - no power. The outlets are at the end of a circuit run. I can follow the dead circuit back to the first outlet in the room where the circuit enters, but then I'm stuck. That's because the basement is almost completely finished AND THE CEILING IS DRYWALLED. There are no issues in the rest of the house and none of the breakers or GFCIs in the house are tripped.

Since we don't use this bedroom very much, I am not sure when this happened (they did work many, many years ago when it was my son's bedroom.) My suspicion is that it happened when we had some major renovation work done in an upstairs bedroom/bathroom.

Is there any trick or tool to "tracing" this circuit to see where it goes behind the finished walls? I purchased one of those circuit tracing tools with a transmitter that you plug into any outlet, but it reqires that the circuit be energized.

Any ideas?
