Yesterday the fiance was in the kitchen and complained that one of the lights (three separate single bulb lights on the same switch that hang over our island) stopped working. Had worked fine earlier in the day.

Checked the breaker, nothing tripped. This light is on a 3 gang switch plate with two other light fixtures elsewhere in the room which were and are still working fine. Checked the 3 bulbs in another fixture, all fine. Got my voltage tester out and checked the switch for the effected light, both the traveler (1 of 2) and the common have power when switch is on. The other traveler (2 of 2) and the common have power when the switch is OFF. They're never all on together. Light still doesn't work.

Replaced the switch. Problem persists. Thoughts?

Have you tried making sure the bulb is screwed in tight? Why would you suspect the switch, if the other lights on the circuit work? Have you tried replacing the light fixture? –  Tester101 Jun 25 '12 at 12:00

Often with light fixtures, each light has a pair of wires that come up and out of the fixture. You wire all of the hots together with the line hot, and all of neutrals together with the line neutral. If the wire nuts that connect all of the wires were not installed properly, it is possible that one of the wires is no longer making a solid electrical connection. It is also possible that one of the wires is damaged.

I would suggest that you remove the light fixture and examine all of the connections. Look for loose wires (you should not be able to easily pull them out of the wirenut), nicks, burns, etc.

If everything is visually OK you should test each wire to each socket with a multimeter. Test for continuity by ensuring resistance goes close to 0 when you make a connection. Repeat this until you find the problem. Make sure the power is off when you do this.

Everything was tight and didn't seem to be disturbed...Don't want to call an electrician but it seems like I may have to. –  Steve Jun 24 '12 at 21:47
    
I'd replace all of the wirenuts to verify the connections. –  Steven Jun 25 '12 at 13:17
