I have two 3-way switches controlling 2 ceiling lights. Last night the 50W halogen bulb on a transformer burned out, and the incandescent flood would not turn off. So I unscrewed the light bulb and went to bed.
This morning I removed the transformer and replaced it with a housing for another incandescent flood. Both floods came on and would not turn off by pressing either switch. (The second switch is in a bank of switches, and I don't know which one controls the light, but none of the switches in the bank worked.)
My problem: The existing switch is a Lightolier ZP600VA dimmer with four wires: black, white, red, and yellow. Those wires are connected to black, white, black, and yellow wires respectively.
All new replacement 3-way switches have three wires. So am I heading in the right direction by assuming it's a bad switch? And how to I handle four wires in the wall with three wires on the switch?
Any help would be appreciated.
