alternative wiring

Sorry to say this but maybe an electrician needs to come round and check it out.

She is an electrician....

Nat - your diagram doesnt make sense if its wired that way. why take live & neutral to switch, then same via 2x 2core to downstairs. the diagram Sarni has makes the most sense and looks to be the only one which would work by the cables you have

I will have a stab at this, chok blok the feed line / neutral from the loft to the feed line / neutral down stairs and at the landing switch connect the neutral from the light to the neutrals in the neutral chok blok, connect the switch live on the landing to the common on the switch, and the two strappers to l1 , l2.

On the ground floor connect the feed you have chok bloked at the landing to the common on the ground floor switch and the two strappers to l1 , l2 if the neutral is not required on the ground floor just make the end safe CJS

Welcome to the Forum Graham,Guiness Drink

I will just make this quick observation, hopefully polite and clear (please take it as it is intended) :x

1/ at the point when you pass you C&G's and can call yourself a qualified electrician, You don't automatically have an electrical brain memory pack plugged into the back of your head with all answerers ready, there and waiting just to be recalled when you have your first problem.

2/ when coming across obscure/unusual methods of using conductors to achieve light switching, (especially two-way), it can sometimes cause a bit of confusion.

3/ when working as a sole trader, (with no one to bat your ideas around with), it can be very easy to run yourself round in circles and end up throwing yourself off track for a short while.

4/ this is where a good polite forum, (maybe a bit like this one?), is a great help to chat things over without embarrassment, so that you can learn your error sort it and move on to the next problem.

5/ I am 101% certain ALL good qualified electricians have dropped the odd clanger here or there, or missed the bloomin obvious staring them in the face. Then learnt from their mistake, added to their experience which they can then keep for future reference.

I think some or all of the above points possibly summarise the process of debate/discussion/chat that is progressing quite nicely on this thread!

But then I may be wrong..

After all I am only another electrician, who has made his own share of mistakes in the past and had to learn from them.. :coat

(probably had me own share of two-way light head scratchers as well!:|Blushing)

after all we ALL have to start somewhere. But its probably best, as me mum told me, don't make assumptions, check the facts first! :|

FACTOID:

The lighting circuit under investigation involves NO aspects of legislation requiring any qualified registered or authorised person of any sort to have to undertake the work.... {NOT Part P related work}

So if it was your choice even a non qualified DIY bob (VET's or Plumbers included!) can quite legally mess around to their hearts content trying to fix it.

Hopefully, Graham, I have sort of summarised a bit of how this forum works,

so grab yourself a Guiness Drink and have a look around the rest of the place.

and I will go back in the corner with my colouring book...

cuz AndyC got me the wax crayons off Patch!!! ; \

and Patch don't know yet that his crayon box is empty! ]

I am inclined to agree with the AndyC & Sarni (Drwg2) method..

But there does appear to be a classic shared supply to both upstairs & downstairs arrangement!

As andy said Nat your drawing shows a bulb across two contacts of a switch?

this is clearly wrong.

My guess is some time in the past someone has done the old

join all the reds together and join all the black together!

Personally I would disconnect everything meter and/or buzz it all out

clearly identify each of the following:-

Supply cable.

Bulb connections.

Strappers.

Then re-build !

ob done

OK here goes....yes there are way too many wires in that upstairs light switch, Im suprised anything works

Anyway Ive redrawn the curcuit... even in old colours especially for you!

Guiness Drink

Concur!

I think that is most probably it looking at the number of cables etc!!Applaud Smiley

If Avin.. was close to me i would pop over a give her a hand

nothing worse than struggling on your own on a 2 way lighting cct..

looks aswell there is a shared neutral

personally looking at all the diagrams i would try and wire it via down a downstairs feed.....much easier in this situation

if a downstairs neutral was available

 

[sarni31]

How did it go ?

Have you managed to sort it?

Thanks Theory Applaud Smiley. Shame there's not more sparks like you guys around

You're telling me :_|

 

[avinalarf]

Thanks for everyone's input.

Won't be able to get back to this client for a few weeks, but will let you know the outcome when I've [hopefully] sorted it out
