Wiring a Ceiling rose light.

[Zammo]

Hi

I have just been attempting to wire up a ceiling rose light. I copied how the old light was wired up onto a piece of paper and then when I wired up the new light I actually left on the old rose and placed it over the top (it was a chandileer type light) and used the notes to wire up the new light, the light was controlled by a dimmer switch.

However I have a bit of a problem, when I connected the power, the light cannot be controlled by its dimmer siwtch in the dining area and will only dim when I adjust the living room lights, which in turn are just barely on when the dimmer is on full.

Looking at the forum wiki, I think I realise my mistake, namely there were three bunches of wires coming down into the ceiling rose and they should have been wired up in a certain order, but I didn't realise this at the time and wired the coloured wires into the right blocks but didn't neccasarily put them in the right holes.

Is there any way I can tell which wire bunch needs to go into which hole on the block?

Have you got a multimeter?

If not, walk up to the high street and buy one for less than a tenner, then come back here.

Ok a trip to Homebase seems in order, be back soon.

Thanks

He's only joking like. You don't need one.

No I'm not.

We will be looking for continuity between quite a number of wires, followed by voltage and resistance tests.

With a meter it will be a breeze.

Sssh man

Wel I havn't got one yet. I'm gonna goto to an electrical shop tomorrow, where incidently I need to change some things I bought so will be killing two birds with one stone.

Mighty Quinn why are you saying I don't need one? If you know of any way I can determine which wires are what without a multimeter please enlighten me.

I was being mischievous, sorry

When you get your multimeter, put it on continuity, or if it has a buzzer, this would be better.


Turn the dimmer off.

Turn the lighting circuit off.

Put the test leads across a pair of cables at the light fitting. One of them should have no reading/ buzz. Turn the switch on ( better still get someone to do it for you ), and check the reading again. If you get a reading, this is your switch wire. Then follow the drawings for wiring a fitting in the Wiki.

Have you changed any switches?

No

I've just had a thought. If the only coloured wire I have to get in the correct hole is the switches black wire (which goes in the live block next to the light's Brown wire). Then I only have two other possible combinations that I need to check to get the light working correctly. All of the live (red) wires go into the same block so I don't need to distinguish between them. Is this correct?
