Hello all,

I'm replacing a 3-bulb spotlight with a standard BG ceiling rose but upon connecting, the light won't turn on; the problem is, I can't see why.
We can handle the wiring shortly, but after a day or two of testing - wiring the spot back on, test (it works), replacing with the ceiling rose (it doesn't work), I finally gave up and wired the spotlight to a plug and tested - dropping the 13A down to a 3A first.
The spotlight predictably worked as expected, but upon switching over to the ceiling rose, using the same bulb as the spotlight - it's a 7w bulb, I'm not getting anything, although I am registring power both on the cable terminals and, the light terminals, just no light. It's as though the light terminals are performing a huge resistence that the power could not overcome it and light the lamp.

I have already gone through the motions of junction boxes and switches trying to troubleshoot, which came-up blank - even to wiring the rose direct to the light cicuit and the junction box in the attic [we're still on junction boxes for the lighting circuits rather than using the rose loop] to bypass the switch [using the RCD as a switch], and predictably, I got nothing, hence the direct to wall-outlet approach as a last resort.

Any ideas?
 
The photos of the connections as requested.
  • Pic 1 is the spotlight wired to the plug - it is working, no disputing that
  • Pic 2 showing the 3 terminals of the spotlight connected to the plug - the spotlight is metal so the earth is required
  • Pic 3 is with the Earth released - just so we know that there is no issues with the earth as the problem lampholder is plastic, it can't be seen in shot, but the spotlight is still illuminated
  • Pic 4 is the problem lampholder wiring at the lampholder
  • Pic 5 the lampholder to power cable circuitry - as mentioned above, no earth
  • Pic 6 - no light - it isn't showing but the plug is powered on - I had intended to include my circuit tester in the shot but my camera was being awkward so I just didn't have enough hands - hence my circuit tester in shot in pic 4
  • Pic 7, a close-up of the lampholder wiring, just so you can see that we're connected to the correct terminals. It can't be seen from this shot but the light is off (those reflected in the work surface are the kitchen lights), but the power is on.
