I have an older mobile home, 80's model. the light switch in a bedroom busted out of the wall so I went to replace it only I am confused about the wiring.
Normally I am fine with this when replacing new lights and stuff but I think this was done wrong. There are two sets of wire bundles in the wall, each with a copper black and white. The switch had a black one the bottom side screw then a copper on the screw above it both from the same line. Then the two whites are put together. Then on the top screw is a wire with black on it and and not positive cause it got pulled out but the copper wire might have been on that same screw and if it wasn't then it was just there in the open.
What is going on? Does that mean two things were hooked up to the switch? But then what?
