three wires but 2 are already carrying power
I opened an outside electric box that supplies power to my fountain. The GFI appeared to have failed. When I pulled the pump motor plug the plug was melted to the GCFI and the GFCI had a burn hole in it. As I removed the 3 wires I strted to notice some funky wire match ups. The whire wire aws attached to the load side of the GFCI. The red wire was attached to where th white should be on a GFCI and the black wire was attached to the green ground screw. Kepp in mind this had worked for 5 years. As I pulled the wires I found 121 v on the red and zero on the white, them found 91 volts on the black. Brought in a new known ground directly from the panel and measure to that. Red to ground= 121 v, white to ground=0 v and black to ground= 13 v. I switch the white and red back and forth on the two terminals and always get a reading on mytester that the nuetral and hot are reversed. This is just driving me nuts and starting to tick me since I used to be retty good with this. Who out there can enlighten me on my wiring?
