Apparently it's not unusual for this type of tester to show that result under certain circumstances. I agree it's odd.

I've tested the house before and know that all of the outlets tested normal, so it would be unusual for an entire circuit to rewire itself after 40 years. I understand that it could have been done originally, but I'm certain that it wasn't.

I understand that there's a fire hazard. Unless you're going to pay to replace my wiring I'm going to keep going the way I have been.
