how to bypass dimmer in sconce

tsknMarch 15, 2014

For the past 9mo I had no problem with a dimmable wall sconce (two lights) that uses two 12V halogen bulbs and a transformer. One of the lights buzzed and then failed but I fixed the buzzing and illumination after replacing the transformer and wiggling the lampholder.....but it only worked for two days. Now both lights are out. I don't know why it's failing, since I wired it well and nothing seems to be visibly problematic. Is it possible to bypass the dimmer/transformer and have the light just be on/off on the same dimmable knob?

The only thing you could do would be to take out the dimmer and install a normal switch

Halogens get very hot. Wiggling the lampholder suggests that heat damage has occurred and poor contact is the result. At this point, every component of that fixture is a suspect.

So after more troubleshooting it looks like the lampholder and transformer are shot on the original bad side. The other light works again after changing the bulb. Can I assume that all the wiring is fine and all I need to do is replace the bad lampholder and transformer? Thank you in advance.

So I'm trying to replace the lamp holder. After stripping the wire to attach it to the new lamp holder, I see the color of the wire is dark instead of silver. Does this mean that that wire is bad and needs to be replaced?
