A light that has a 2 wires (and a ground) coming in from an outlet. The 2 wires are unused.
From the other side there are two wires coming up to the box. 1 of these wires connects to the light and the other connected to the ground wire from the first bundle. A third wire connects the bundle to the other side of the light.
I understand what is going on here - the people who setup the light (for whatever reason) used the ground as the neutral, not sure why since they had 2 other wires they could have used.
Anyway, when I was trying to figure out what was going on I disconnected all the wires at the switch & up in the light box. When I disconnected the ground coming from the outlet the 2 wires from the switch box showed hot from my cheap voltage meter - they were not connected to anything on the other side...
Why were they hot?
