Friends have an older home that's been added onto twice. In the yard they dug up a live wire. You can take a screwdriver and carefully short this wire all you want and it stays hot.
This house does not have a main breaker on the outside of the house.
Even getting at the fuse panel in a nightmare, but the only thing I can think of is that during one of the add-ons someone hooked this wire up behind the fuses without using a fuse and the reason you can't get a breaker to trip shorting the line.
Am I going to have to work my way back to the fuse panel and find the un-fused wire?
Any other ideas where this mystery hot wire that won't die might be coming from?
