Two way lighting not working

[peter m]

Are you saying one of the wires that was originally taped up lights up your voltage sensor ,and no other wires do ?
You would be better off buying a multimeter ,those volt sticks are not gonna be much use to you for fault finding.
Yes ,it's possible that pulling on wires could cause a disconnection. So could many other things ,hence me asking the questions below.

That remain unanswered.

No issues with ceiling rose all connections secure

No issues with ceiling rose all connections secure

Is that the ceiling rose connected to the switches in question?
If so ,is the permanent live to the switches fed from that rose ?

 

[peter m]

No idea but it must be if those switches operate the light , I'm not a spark so guessing

 

[terryplumb]

Pictures of the wiring connections at the rose may be useful.
If the permanent live to the switch originates there,that would be a starting point,followed by tracking the cable in the loft. Hopefully it's not boarded over up there and you can access the cables !

I got a loft conversion

Oh sheeite !!
The switch cable appears to come from the rose, fairly standard loop In wiring.

Very helpful NOT

If that’s an example of the standard of the electrics in your house I would recommend you get it tested and inspected thoroughly.

Would you rather people didn’t suggest recommendations?

Jog on pal

 

[securespark]

Yes. You too.

Get an electrician.

 

[SUNRAY]

Yes. You too.

Get an electrician.

Yep that certainly is the easiest way to close the usefulness of a thread.

We can now do pages about exercising... oh apologies I meant Jogging.

 

[peter m]

Yes. You too.

Get an electrician.

I fixed it ye mugg

 

[terryplumb]

What did you do Peter ?

 

[securespark]

Are you going to tell people who visit this thread in the future what was wrong?

The reason I backed out was because I am one of several qualified electricians here who freely give their time to help people with electrical problems.

But it annoys me intensely when those people just throw insults at those trying to help.

The other reason I suggested getting an electrician is because the wiring and boxes you have pictured in post #8 need to be modified to be made compliant and safe.

.

What did you do Peter ?

I'll make the guess

With this one the black and blue have come out to the terminal.

Not possible, they likely pulled out when you removed switch the at moment empty terminal will have the unused wire either red or black from two core, and the blue from three core.

Have it your own way, but it will not work.

As Eric has tried to tell you these wires were in a terminal before you removed the faceplate of that switch. Perhaps the screw wasn't tight but they were in the terminal and they were making a connection.

You come on here asking for help.
Regardless of what YOU THINK; the advice given about 5 wires is totally correct.

What I see in you pictures is a yellow wire, correctly marked with red tape to indicate it's a live wire and a blue and a black wire, correctly marked with red tape to indicate it's a live wire.
Somehow the blue and black have become disassociated from the switch.

Do us all a favour and terminate the taped up blue and black in the spare terminal and try it.
THEN we can start with other advice IF it still does not work.


This is how it was wired when it was working properly:

Compare that with what you have now.

If you still have the green sleeving please put it back on the bare earth wires.

I will add: Well done for taking the 'before' pictures, it has helped us a lot knowing what was there.

However if it is, OP will no doubt deny or ignore it, or tell us it was something else entirely.
