I have just attempted to put up 2 new light fittings in my lounge but am confused with the wiring. A double dimmer switch at the wall used to turn the lights on but now it will only switch one on as I seem to have forgot how to wire one of my lights. The light which works just had a black, red and earth cable coming from the ceiling however the other one has the following: 2 reds, 1 yellow (with a red sleeve), 1 blue, 1 black and the 2 earths. One of the reds is permanently live and I think the blue is a neutral as it tripped the fusebox when I connected it with the live red one. My light fitting just has the usual brown, blue and earth connections. Any help would be very grateful!
Thanks, Lee
