I have installed light fixtures before, but always on a light with a single switch, and with only black, white and ground wires. Now, I am trying to install an Ikea light fixture that has a black wire, white wire, and 2 yellow & green striped wires. The ceiling box has two black wires, two red wires, and a white wire. The room has two switches for the one light. I first tried to hook the black to the black wire, the white to the white wire, and I think the striped wires are grounds, which I connected to the ground screw. I didn't hook anything to the red wires. This didn’t work, and it blew the fuse. I then disconnected the black from the black wire, and reconnected the black wire from the fixture to both red wires. Nothing is connected to the black wires in the ceiling. Now one switch turns on the light, but if I use the other switch, it blows the fuse. 1. Am I correct that the yellow and green wires are grounds? Should they be connected together? 2. What can be done so that both light switches work? Thanks

Hi, thanks for reading. I installed a low voltage track light that accepts MR16 bulbs. Originally, I wired in a sliding dimmer switch, but when I powered the circuit, the lights did not work. Reading the documentation, I see that only low voltage electronic dimmers are to be used with this track light. To test the light, I removed the switch from the circuit. Still nothing. I checked the voltage across the red and black wires in the switch box, which read 120V. I checked the voltage in the track, which was about 44V. When I checked the voltage across the holes where the bulb goes....no reading. I had three other of the parts that fit into the track and accept the bulb, so I tried all of those with the same result. However, when I put the probe in just ONE of the holes, with the other open to air, the multimeter read 12V (which is what I think I need). Do the measurements sound correct? Is it possible I fried the transformed in the track by attaching to the wrong dimmer? Thanks, Ned
