I have looked at some of the threads in here and some come close but
just not all the way

I have a landing ceiling light with another switch downstairs.
I recently bought a new light from IKEA.
I have wired it up and it works. Unfortunatley my bedroom and the box
bedroom does not.

Coming out of the ceiling are three grey cables each with a Red, Black
and Earth.
All three earths are sleeved together.
There is also One wire heavily sleeved in Red.

I have two blacks going to neutral
One black and the single heavy red going to live
and the three reds together


Why are my other two bedroom lights not working?

What you have is a line and neutral in, line and neutral out to the next
fitting, and switch pair. (the two way switch wiring will be from the
switch, so needn't concern here)

Ignoring the earths which should simply be connected together and to any
fitting that needs one, you should have:-

Three reds connected together but not to the fitting.

Two blacks connected together and to the neutral of the fitting.

One black - sleeved red - which is the switch return, and connected only
to the live on the fitting.

See the explanation and diagram of "loop-in" wiring for a ceiling rose
half-way down this page:

http://www.ultimatehandyman.co.uk/lighting_circuits.htm

You should have no black wires connected to anything live, switched or
otherwise. The switched live wire is nearly always sleeved in red, as
you have found, to avoid the appearance of being neutral. It sounds
like you have moved the neutral for your other lights onto a live
connection and there is no circuit any more.

Note on the diagram that there is no logical difference between the
supply "in" and the supply "out", which are simply connected together.
The only wire you need to positively identify and wire differently is
the switch wire, which is hopefully the one you have found to be
sleeved.

What I have noticed this morning is that when the light is switched off
the bedroom lights do work.

Thanks for your help.
I will adjust the wiring this afternoon

This is topical because we've just taken down the light fitting in our
sitting room, which we're painting and I wanted the ceiling to be done
properly.

It hasn't been moved since it was put there, at least thirty years ago, and
I'm glad I insisted on taking it down. The flex is fabric covered, the
connections to the bulb holders (four) were crumbling. Wire was twisted for
joining, with those porcelain caps.

Ceiling lights, unless they go wrong or are replaced fairly frequently, tend
to be ignored. I think we'll be looking at the rest of the house after this.

Hopefully it is just the lighting circuit(s) that are wired in this
sort of rubber insulation, or even better just the drops.

It should be replaced as a priority, though if left undisturbed it
may last for a while longer.

It's not rubber, the wires are insulated with plastic but the flex is
covered with fabric.

It IS being re-wired. The supply to it was replaced, along with the the rest
of the house rewiring, some years ago. That room is the only one which has
been undisturbed in those years.

My point was about fixed appliances with original wiring. how many of us
check them?

Strange, I can't recall coming across such flex.

Not enough.

You're not old enough :-)

I wonder how often we should check them? I suppose it would be different for
different appliances or when the wiring was installed - it's a minefield!

It's still available from the likes of Christopher Wray for period table
lamps, etc. Usually with gold or purple fabric covering. Was commonly used
for pendant cable 40years plus ago, so doesn't really owe you anything.
However, if the permanent wiring has been changed it should have been also.

Every ten years is generally fine for fixed wiring. However, to make
that sort of judgement people need the proper training.
