Wall light issue

[Qas06]

Hello all, I can imagine his question has been asked a lot on here already however I can't find the answer to my problem.

I have in my lounge a 2 switch light socket to control the ceiling light a 2 wall lights. Everything was working this morning but since i replaced the wall lights 1 is working and 1 isn't, bulbs tested and fittngs have been swapped even tried the old fitting that did work but no longer does

Ok a bit of info about the wiring
Light 1
2 grey cables with wires joined together
2x black
2x red
2x earth

My light fitting is 2x black to blue (neutral) and 2x red to brown (live) and 2x earth to earth
Switch on and brill it's working!!

Light 2
1grey cable
1x black
1x red
1x earth

My light fitting is simply 1x black to blue (neutral) 1x red to brown (live) 1x earth to earth
Switch back on light 1 still working, light 2 is not, being that light 2 is more simple to wire it's failing to work, I am thinking the error maybe in light 1 as I believe light 2 is Branched off light 1

Can anyone offer any advice to get my light 2 working ??

Thanks[/i]

As it is light two which is not working the fault could be at either light and must be on the cable which connects the two.

It can only be a badly connected or broken wire.

As you have done it several times with different combinations it presumably will not be obvious.

Check that the actual conductor is not broken inside the insulation, ie a very floppy end.
If you have a multi-meter check for continuity at the ends of each of the wires.

If you have a multi-meter check for continuity at the ends of each of the wires.

And if you don't then get one - is is as essential a tool to have if you want to work on your electrics as screwdrivers, wire cutters and strippers etc.

Neon screwdrivers are questionable from a safety POV as they use your body as a current path, and they are desperately unreliable - to safely check for voltage you must use a 2-pole tester, such as a proper voltage indicator or a multimeter.



This looks ideal for a household starter set - multimeter, voltage indicator and dedicated continuity tester, all in a handy case: http://www.amprobe.eu/de_DE/showproduct/115/Junior-Set/

All in German, unfortunately, as is the blurb on each product:

but it is sold in the UK - the company is now owned by Fluke, and I guess they haven't got all the websites sorted out yet - contact them (http://www.fluke.co.uk) for info on where to buy.

Right now the English specs are still lurking on the Internet Time Machine from when Beha was an independent company:

Also see another discussion here: //www.diynot.com/forums/viewtopic.php?t=26282 It's a few years old, so specific model number advice may be obsolete (and prices will be higher), but the generic advice is still sound.

No link conductor between com of each gang on old switch?
How are the cables terminated at switch one? You say you have pairs of each conductor, where do they go to on the switch plate?
Is the neutral looped in at the switch?
