After replacing the light bulb, the switch in the wall and the socket and the wiring within the fixture, my porch light still doesn't turn on.

I suspect that either there's:

1. a problem with the wiring in the switch box in the wall
2. a break or short in the wires between the switch and the fixture.

I have photos of the wiring in the switch box in the wall and the fixture's junction box.

How do I check the wiring?



Note: When I hook up the fixture to the wiring on a different switch, the light does turn on
