I have replaced my landing light fitting which I thought woudl be straight forward.
There are two Twin and Earth cables coming from the ceiling plus a single red wire.
This gives three red and two black.
I wired the single red to the lamp flex Brown and the black form one of the t&E to the flex blue. The landing light works fine, as a two way with a switch upstairs and one downstairs.
Out of the remianing two reds , once is a constant "live". I think the other red goes down to the bathroom light switch and the black is the switch wire coming back. Connecting thsi red to the Constant live certainly makes the black switch wire live when the switch is operated. I have connected this switch wire to the same connector as the brown lamp flex.
Problem - The bathroom light only works when the landing light is turned off. However the landing light still glows dimly at this point.
Turning the landing light on gives full illumination on teh landing but turns off the bathroom light.
What have i done wrong?
