Ceiling Wiring Confusion (4 wires)

[DIYnewbie]

Hello forum,

I'm stumped about how to correctly and safely wire up a new light fitting and stupidly didn't take a picture of the existing ceiling rose set up before removing it. I was wondering if someone here could help me out! I've attached a picture of the four wires that are coming out of the ceiling, and I think the top black wire was going into the hole where the brown wire was connected on the ceiling rose pendant, and the bottom black wire was going into the hole where the blue wire was connected on the ceiling rose pendant. The other two must be part of the switching loop? But I just can't figure it out correctly, and have tried a couple of combinations only for the trip switch to go every time. In terms of the connection of the new light, it has just a blue and a brown going into a junction box that has 4 holes available on the other end, 2 that are lined up with the brown and 2 that are lined up with the blue...
Does anyone know how to correctly fix this?
Thanks in advance!!

Thanks for all the responses. Sounds like the wiring is a shambles! Really didn't want to be paying an electrician for what seemed like a tiny job, but I may well have to now by the sounds of it. Cheers

Have a look in the light switch to start tracing the intended use.

Oh dear. The easy light changer over *Sarcasm

No offence OP. Get a Sparks to look at it.

it appears to have cutoff cpc's in those cables, so might not be a difficult fix. if it wers within my area, between £40 and £50 would probably cover a call-out , test and fix.

Join the red to the brown using a connector block.
Insert the two black wires into the L and N.
See what happens.

I wouldn't be giving any advice on this except seek professional help.

. . . . . and then medical help!
The bang test gets a bit old with a 3036 board - rewiring a fuse just to try again - we're spoilt with these new fangled MCBs you know!

nowt wrong with a 3036 fuse that a 2" nail won't cure.

@telectrix - back in your basket, bad boy!
How are the pups, have you been keeping us informed on the maternity thread?

we lost 2. 3 remaining pups doing well.

Sorry to hear that of the two but great that other 3 have made it - a miracle in its own right. Smell them for me! I love puppy smell.

Yes that may work, but it does not resolve the earthing issue, not only is there no Earth connected in the ceiling but it is very likely that the switch is not earthed either!

Get an electrician

This was one attempt by the way...but this causes the mains to trip too

RED with Brown at separate connector Black from red to N and Black from Brown to L

this is the last point in circuit and new 3core is running from switch )

This may well be the case but what about verifying continuity/connection of the cpcs.

 

[westward10]

It is also impossible to connect those cables at that fitting in a compliant manner.

You have right about cpc , they have to be connected
