Well, my 1969 house needed a sliding glass door. I took out the large window and cut out the bottom, fitting in the slider. All nice. But I had to remove one outlet from the wall right where the door now is. I just want to connect the two ends of the flex cable and wires. There is power coming from the left cable end. I connected the three wires, red, white and black, and nothing. Disconnected and now no power. The circuit breaker works, controls an outlet in a nearby bathroom, but nothing happening now in the old cable ends. Any thoughts? Thanks.
