The outside light on this trailer is not working. I drew a diagram of the wiring on the switch inside. I can only assume that the switch inside that does nothing is connected to that light. I tested the light socket with a multimeter and it showed no voltage. I replaced the switch on the inside and it still doesn't work.
It is a double switch. The switch on the left operates a light inside the room. The switch on the right is what I assume operates the outside light. I just bought a brand new bulb and it's not that. It is the kind of bulb with two socket connectors that you twist on.
Inside the light switch, there are four sheathings coming in. I will call them top left (TL), top right (TR), bottom left (BL) and bottom right (BR). Each has a black, white and copper ground. The white from all four go into a wire nut. The copper from all four go into a wire nut with a hole at the top where one copper wire exits to loop around the ground screw on the right switch and screwed into the ground screw on the left switch.
The black wires:
TL - top of left (indoor) switch
TR- top of right (outdoor) switch
BL - bottom of left (indoor) switch
BR - bottom of right (outdoor) switch
There is also a black wire that is stabbed in the back of the right switch and connects to the bottom of the left switch.
