Shocking Surprise

If the property is on a well, there may be a lot of iron in the water. Sometimes, that will build up on the heating element in the water heater and start shorting out to the tank of the water heater, which is tied to the frame. It will give just enough voltage to make you feel a tingle, but not enough at that point to trip the breaker on the water heater. If you still feel it even with the new cord, flip the breaker off that feeds the water heater and see if it goes away. Hopefully, it was just the fubared power cord.
