I've got the three separate ceiling lights all on the same switch. The other two are simple with a single grey cable fitting. But this one is obviously the key light because it has three main grey cables.
When I wire up this one up according to the diagrams available online I find I can't switch the lights off.
I've used this diagram as a guide, though there are many similar. It fits my setup/wiring/colours almost exactly (except in my case the original installer has taped one of my blue wires (which I understand to be my "switched live") red instead of brown as in the diagram. I presume that's an entirely cosmetic difference.
So, retracing my steps I detach all the light fitting paraphernalia and just try it with the three brown/live wires bound together (as should be standard according to the diagram) and still its sister lights (on the same switch) won't turn off. To kill the light I actually have to disentangle the three brown/live wires.
What am I doing wrong?
I guess this question looks much like this one, but the best answer has the same diagram I feel I have worked from (except different colour scheme).
Edit
Per Tester's answer, and if the diagram is wrong do I need to move one of the browns over?
