Hot to ground and neutral to ground read 120 V. Hot to neutral 0 V. This is a portion of a circuit that appears to be at the end of the wiring. An overhead light/fan and one duplex outlet are not working and show the above readings. Everything else on that circuit appears to be working properly, with voltage between hot and neutral and hot and ground 120 V and 0 V neutral to ground. That portion was working until a few days ago.
Neutral to ground should never read 120V. This means your neutral connection back to the breaker/fuse box has gotten disconnected somehow. That needs to be found and fixed.
