Hi there,
As part of my 'Credit Crunch' kitchen overhaul, I've decided to replace the ceiling lights there.
I have 2 sets of 2 spotlight bars currently, which I'm trying to replace with new spotlight bars. The current ones are connected to a loop in wiring system (the second running off the first)
There are a couple of areas where I need some guidance, however.
1. When removing the first set of lights, the connector strip was squeezed tightly up into the ceiling in such a tight space that I had to unscrew the wires before I could remove it. As a result, I couldn't tag the wires, and Sod's Law, when I eventually managed to get the 3 twin-and-earth cables out, the installers hadn't marked the switch cable! Having read the posts elsewhere on the site, I have tried using a digital multimeter to identify the black switch wire while flicking the light switch, but the reading I get from all the cables tends to fluctuate quite a bit without even touching the switch, before settling down to near zero. Annoyingly, the multimeter doesn't have a continuity test function either.
Am I best off getting another multimeter (with continuity buzzer), or is there another (cheaper!) way I can identify the switch cable?
2. Having looked at the wiring diagrams on the site so far, they all seem to apply to ceiling roses. However, my new lights contain a connector strip with only 3 pairs of terminals which is fixed inside the fitting (see picture below), though the fitting instructions are pretty useless I'm pretty sure that I need to use another connector of some sort.
Can someone tell me how I should wire this up to the three twin-and-earths and whether I need to get any other bits, e.g. a choc box
Many thanks in advance!
