I have a wiring problem I hope you can figure out. As you can see from the picture, I'm installing a new ceiling light. Having taken off the old fitting there were two wires which suggests that its at the end of a loop. I have therefore continued the loop with the two live cores and fixed up the neutral to the feeder wires of the light. The earth is pretty much as standard. In theory, this should work however it does not. The light switch works ok (suggests the loop is fine) and its not tripping the fuse box. Good so far. The problem is when the light switch is in the off position, the bulb is still lit (albeit dimly). To me it suggests that there is maybe a problem with the ceiling rose that's allowing power to come back down the circuit (hope that makes sense). The reason for my doubt is because the circuit worked ok before I changed the light so I question why it would be different now? I tried keeping track of how the previous light was wired but it was really old, gave no clues and I had bucket loads of dust and plaster board falling in my eyes. Any solutions (short of getting an electrician in)?
