Light Out

There are 2 ceiling fixtures in the guest stateroom, controlled by the top/1st of 3 switches on the panel next to the door.

For a couple of months, the lights would turn on, but only after several attempts. Now, the lights just won't come on.

I don't think it's both bulbs. But, I did remove and replace one of the bulbs with a new one, and still nothing. I pulled the switch, removed then reinserted the 2 wires, still nothing.

Any suggestions? Can the switch itself go bad?

sounds like a broken wire to me. switch failure doesn't seem likely. you can test this by moving the wire to the middle switch to see if you can get them all to come on. let us know.

you could also disconnect the wires from the switch and test continuity across it.

I'm recalling an intermittent problem I had with aft head operation several years ago. I had to recrimp the connectors on the wires to fix that. there just wasn't quite enough clearance, and the wire had been pulled just so far out. the original crimp also wasn't so great.
 
switches can definitely go bad, however I am not sure your description of intermitten functionality is a switch. I have had switches at my house go bad - like anything - nothing is built forever anymore.

This sounds more like a lose connection.
 
Someone correct me if I'm wrong, but since these are part of the 12v system and there is not a real concern with handling live wires, couldn't you just jump the wires at the switch and see if the lights come on and eliminating the switch to test?

Theoretically yes. But if you've already got 1 electrical problem, why risk the possibility of either creating another, or hurting yourself? Life's too short.

go to youtube and search for "12v battery dead short", and look for "short circuit.mov". personally I think the guy's a moron, but it does demonstrate the point.
 
Yeah, that guy does demonstrate potential but we are talking about protected circuits. OP doesn't mention breaker being tripped so I don't believe there is a short anywhere. Coming from the automotive field testing the way I mentioned was common.

Thanks for the replies. I should've mentioned it, but the breaker is not being tripped. I will move the wires to the middle switch as next step.
