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 !!!!

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