I have three porcelain lamp-holders that I want to install in my apartment.
I installed one without a problem in my den area, and it works with the light switch. I connected black to a brass screw, and white to a silver screw. I left the ground in the ceiling, as there was no place for it on the lamp-holder.
My problem is with the bedroom
I have tried to do the same as the den, connecting 1x black wire to a brass screw, and 1x white wire to a silver screw. I left the other black wire capped, and left the red alone. The problem is, the light stays on all the time - regardless of the light switch position. I have tried both an LED bulb, and an incandescent bulb. Both stay on constantly. I have tried stripping the red wire and using it in place of the black wire, and the light did not turn on. There are no other switches that control this light.
All wires are capped back to their original states (as depicted in the photo).
Why does my light stay on constantly?
