I HAVE REMOVED A DEFECTIVE DIMMER SWITCH AND AM TRYING TO REPLACE WITH A STANDARD 1 WAY LIGHT SWITCH.THERE ARE 2 REDS;2 BLUES;2YELLOWS AND 1 EARTH. I HAVE TRIED JUST CONNECTING 1 RED AND 1 BLUE (HAD A LOOK AT MY OTHER LIGHTS) BUT THERE IS NO POWER? THE YELLOWS ARE THE PROBLEM THEN? HOW DO I WIRE IT ...
