I have a 12V low-voltage track lighting fixture in my kitchen. One of the rails isn't working. If I move the bulb fixtures from the bad rail to the other rails, they light up
A few days ago, one of the bulbs on the (now broken) track burnt out. The other bulbs on the track continued working. I bought another 12V bulb, it was a different sized connector, but it fit into the fixture so I tried it out anyway just to see if it would work (it didn't). I didn't notice if the other two bulbs on the rail stopped working at that point, or it if it was later.
Is it possible for a rail to burn out? I don't know much about track lighting, but I assume these rails are just conductors.
Is it possible that I shorted something to the transformer by putting in the wrong bulb?
Why would just one track stop working?
Upon further inspection, I discovered that the light sockets themselves contain the transformers (inside the white box), the rail is just a 120V conductor.
Some of the lights will come back on if I put them on a different rail and knock on them with my hand. I have yet to take a volt meter to the bad rail to confirm that it's the problem.
