Williams Full House (1966) project.
I had a bulb that would only light up if I moved it around a bit, so I tried using Steve Young's socket cleaner stick. Now the socket blows the fuse to the back box lights every time I turn a bulb into the socket.
I've been troubleshooting with a circuit breaker to save money on fuses, but even without a bulb in the socket the breaker lets go and the back box lights go out after a few minutes.
How could I have screwed up?
Thanks for any ideas.
