So a few outlets on the same circuit suddenly stopped working yesterday, and we suspect that's due to a bad receptacle which is on the outside of the wall. We opened it up, and tried to replace the receptacle but it still didn't work. And it even didn't work if we just leave the wires open(i.e. no receptacle)
So we tried to measure the voltage, and it's pretty weird: 110v between hot and ground, 110v between neutral and ground, but ~3v between hot and neutral, why?
We also checked other outlets on the same circuit and all hot&neutral have ~3v as well.
What could possibly be wrong there?
