Moving on from my wall lights that are hoping to be fixed I am replacing the toilet light. Removed the rose and did the following.
4 earths to a single block then a piece of wire linked to the earth of the metal light fitting.
Four browns to a 3 bit connector 2 into one hole then one in each of the next two.
Black and blue with a brown casing into a 2 block conector together, then linked to the live wire of the light fitting.
two blues into a two block conector then a grey next door then linked to a wire going to the neutral of light fitting.
This was copied exactly from the original rose wiring but now I have no downstairs lights.
A grey a black a brown and earth all come from one supply. Poss could be an extracor
Whats my problem here complete incompetance I know
