light wiring problem

[I J H]

Hi,

i have recently acquired a new ceiling light fitting. i removed the old fitting some time ago, the wiring showed it is of the loop-in variety of curcuit. i fitted the new light but when i came to switch it on - nothing, i double checked the connections to the light, they were ok, changed the bulb - still the same. put the old light fitting back in - still nothing. i took another fitting from another room that i knew worked - still nothing. checked the switch connections - still nothing, swapped the switch - still nothing. i did notice on the switch that both connecting wires were red and neither was marked up as the live feed, but i connected it back up the same way anyhow.

Any ideas what i can try next before i have to resort to calling someone out?

Make up a long lead to the neutral pin of a plug ( the non fused one bottom left as you look into the plug with the back off) and connect to one side of a light bulb. Plug into a wall socket Add a second piece of wire to the other bulb connection and bare the other end of this wire a few mm.

Touch this onto various points in your ceiling rose and switch to see what is live and if the switch works etc.

This should help you draw out a circuit and see what is happening.

And what will it show if a split load CU is used?

To I.

When you say it looks like a loop in system do you have 3 cables which have

3 wires. i.e. 3 earth wires, and then either 4 reds and 2 blacks or 3 reds and 3 blacks?

Might be better to do the wire baring BEFORE plugging the plug in to the socket !!!! Stuart

or even better - invest 5 quid for a basic multimeter from Maplin and save electrocuting yourself!

are you sure you havent tripped the mcb at the cu when wiring up ?

[Keith Lanham]

Have you checked the Fuse ?
