All, I'm helping a friend diagnose a circuit that just stopped working. After some diagnosis, we've come up with the following:
1) The outlet that is not working has 20VAC between the white and black wires (?) and 120VAC between the black and ground wires. Thus, I can power the two-prong lamp off black and ground, but not by plugging it in (between black and white).2) I have not had time to determine what is between the circuit breaker and this outlet, but I am suspecting there may be a bad GFCI somewhere due to the voltage difference between white and ground wires. We did a quick check of the GFCI (by pressing test and reset) and they *appear* to work fine, but I am still skeptical.
Any suggestions would be appreciated.
Take care, Chris
