First easy answer...that's just a spare fuse that I put there. I think the builder added a wire from the box to make it easier to add another circuit at some point. I've moved the spare out of the way.
The only circuit that is working is the middle one which runs the lights and the fan.
Since the other 2 circuits don't work I'm assuming that one is the lights and one goes to the usb/12v sockets which are wired inline. I can't label which is which as suggested by the original poster because they aren't working.
I did the test again (i don't have the trouble light or a multi meter but will get one) and labeled the one working circuit. All use a 5 amp fuse, all of the fuses appear to be fine (not blown) and were just replaced (as step one in troubleshooting).
