My house is 125 years old. I bought it 3 years ago. I am trying to upgrade a wall socket and a light switch in the same wall mounted metal box. I took the old wall socket out which was pretty new and the light switch for my kitchen light/fan which was about 60 years old. When taking it all out I found a white copper jumper wire connected from the socket to one of the 2 screws on the old light switch. I put in my new socket and light switch without the jumper wire and turned the power back on. The socket works and is wired correctly per my socket tester but there is no power to the light switch or the light/fan.
I tried to put in the jumper wire from the gold screw on the socket to the black screw on the light switch. Again socket wired correctly but still no power from to the light switch or the light/fan.
I tried a different copper wire for the jump with still no success.
The socket is a Leviton 2 power & 2 USB power socket. The Switch is a Leviton 3 way light switch.
Can anyone tell me why I have no power to my light switch or my light/fan?
