outdoor light fixture kills everything on circuit
there is a light fixture on the side of the house. it looks pretty standard with white, black, and a copper ground wire, a ground screw and two mounting screws. a dog leash was thrown over the tin light fixture and all of the outlets and lights on the circuit stopped working. when the light fixture is jiggled the power flickers and if it is held at the right angle the power will stay on, but it is very touchy. all of the connections look fine, but i have never heard of one fixture killing everything on the circuit. does anyone have suggestions?
