[James O’s]

Evening. new here so excuse me lol
Anyway I just put 2 ceiling chandeliers up in the front room now the hall ways and bedrooms don’t work. The wiring is old has 3 reds in a block 2 yellow in another separate block and 2 blue separate block with a single black this is the block the light fitting goes to any help would be greatly appreciated

Lol thanks for the advice, usually handy with stuff like this, but this sort of wiring is baffling

Yes I have a 2way dimmer which controls the 2 front room lights But now it seems only the right dimmer controls both lights and no lights anywhere else other then the new ones

Is there a way I can upload a photo straight to this thread ?

Yeah I’m no sparky but I can change a light or switch etc... I don’t get it though I literally disconnected the old lights from the blocks and put a new light up exactly the same and this happened.... I haven’t changed any of the wires, but when I did take the old light down a single black was loose so I assumed that went with a blue

There’s the 2 images of them

 

[James O’s]

Yeah done that on the first and it was fine, but noticed on the second a single black was loose so assumed it come out when taking lights off

 

[James O’s]

Nope nothing but if I put the ceiling lights back up the ceiling lights work but still nothing else

 

[James O’s]

All the other lights worked complete fine even the old ceiling ones

 

[James O’s]

I changed nothing the first light which is the second image I don’t first and took picture exactly how the old light was wired, however the second light which is the first image the wires must have come loose on taking them down and the black single was dangling there

Mate you’re a ******* legend

Was the 2 reds. Weird wiring when nothing’s labelled in old wiring. Turns out the neutral went dead in the end must must have been a kink down the line and a surge blew it. Managed to pull some new 3 core through and changed all to wagos. Thanks for help swifty55 deserves a pint from me lol
