The reds stay together should be in a seperate connection block on there own.
The black with red tag goes to brown side of light fitting.
The other blacks go to blue side of light fitting
Earths to earth terminal should have more than one though check in ceiling void see if you have missed any.
Be safe and isolate circuit.
Yeah everything was done as you instructed in addition to the project pictures I found on this site but still didnt work. Kept blowing the fuses. Anyway got so annoyed with it I tracked down an electrician and it turned out that somehow a wire higher up had become trapped in the new light fitting, cut the wire cover which was then touching some metal and shorting the whole system. All good now.
Just goes to show how difficult it is to fault diagnose when sat at home on your PC answering question, nowt like being there.
Anyway lucky escape and your lights are working now, thanks for update.
