I'm trying to swap a light fixture. I'm used to a fairly standard 3 wire configuration (hot neutral ground) and this is what the replacement fixture expects. When I pulled off the old fixture, this is what I found: The two ground wires were twisted together and not connected to the ground from the old fixture. The two hot wires were twisted together and were not connected to the old fixture at all. The old lights ran between the two white wires.
I continuity tested everything and found the following (indicated by colors in the pictures):
- The two copper wires are connected to the copper ground at the switch
- One white wire is connected to ground
- One is connected to the white neutral wire at the switch
- Both black hot wires are connected to the black hot wire at the switch
I don't know for certain that black is actually hot and white is actually neutral, they could easily be reversed.
What should I do with this? My instinct is to cap off all the wires on the side where white and ground are shorted, and then just make a standard 3 wire connection using the other side. Would that be reasonable? Safe?
