    Mystery grey wire in ceiling rose

    Thanks 333Rocky333 - luckily there are no further changes required. It's finished!! The lights are wired as per the photo I last posted, the switches work and don't buzz. The light case isn't live. HUGE THANK YOU TO EVERYONE WHO HAS POSTED AND HELPED RESOLVE THE PROBLEM! Couldn't have done...

    Mystery grey wire in ceiling rose

    Thanks EFLI! 333Rocky333 - I have the latest picture. The light is now wired as per the photo. The switches are all working independently (not necessarily in the order I mentioned above but Dad is happy with it). So it appears that it might be working (fingers crossed!) The only thing I'd like...

    Mystery grey wire in ceiling rose

    We have progress! Not quite there yet but I feel the end is nigh! Dad has wired up the light as per sparkwright's suggestion. And all lights are switching on now. The only trouble is that they're not switching on in quite the right combination! Switch 1 (from left to right): What is...

    Mystery grey wire in ceiling rose

    Sparkwright - your suggested connections look like the wiring I suggested earlier, which is reassuring as it looks like you've thought it through independently. I like your idea to test for continuity (I do have a multimeter) and ELFI's suggestion to check what's in the same sheath. Thanks...

    Mystery grey wire in ceiling rose

    Yes, I agree, especially after finding a dangling cut wire behind the switch. I am obviously not a qualified electrician, but I do have a degree in electronic enginering so I can't help feeling I might do a better job of fixing this issue (with all of your kind help, of course!) than this...

    Mystery grey wire in ceiling rose

    Yes, the two browns were joined in the ceiling rose when I checked the black wire. When the switch is turned off, none of the wires in the ceiling rose are live. No voltage is detected with voltage detector pen. When all 4 switches are on, voltage is detected in all of the wires (black, brown...

    Mystery grey wire in ceiling rose

    Thanks folks, Below is a picture from behind the switch. This shows the grey wires, as you suspected 333rock333. The greys appear to be connected to two blues, from the photo, which would correlate with AndyPRK's suggestion that it could be neutral. With this in mind, do you think I should...

    Mystery grey wire in ceiling rose

    Many thanks for all your replies. Here is a picture of inside the switch: And here is the ceiling rose (don't take any notice of how they may be connected as it's almost certainly wrong! Also this was yesterday. All the wires are now separated so grey and brown are no longer touching). Let...

    Mystery grey wire in ceiling rose

    My mum and dad have just had their house rewired by electricians. But after they'd gone dad wanted to replace a ceiling rose with a fancier light fitting. In a move classic for my dad, he took the ceiling rose off without noting down where the wires came from or taking a photo. Normally...

    Reverse polarity in light switch

    Hi there, In response to SUNRAY's question, your diagram is spot on. I've double checked and the blue, yellow and red wires from the same cable are indeed connected together in a terminal block in both this and the other switch I mentioned which does make the cable redundant! I guess this...

    Reverse polarity in light switch

    Thanks SUNRAY, I'm at work but will open up the switch again when I get back. An electrician has looked at this in the distant past and couldn't figure out what was going on in this switch! It was baffling as they didn't appear to do anything until I rewired, but getting closer to understanding...

    Reverse polarity in light switch

    The red wire in the same cable as yellow and blue is connected to L2 of the left switch. This is the top left terminal shown in the photo.

    Reverse polarity in light switch

    Ok, got some pictures. Hard to see but: all the blacks are connected together in one terminal block. The yellow and blue from the other switch that used to arecontrol the porch light are now connected together along with a red in a terminal block because there wasn't enough room in the switch...

    Reverse polarity in light switch

    Thanks also EFImpudence. I appreciate your corrections. I don't honestly know what the wiring is in the ceiling rose so sadly don't qualify for your kindness!

    Reverse polarity in light switch

    Thanks for your reply JohnD. It is a 2 gang switch. The right switch is the only switch controlling an outside light. The left switch is now also the only usedswitch controlling the porch light. The porch switch, although now one way, used to be one of two switches controlling the porch light...

    Reverse polarity in light switch

    Hi there, I have just changed an old 2-gang light switch dating from about the 70s (I guess) with a modern one. Once inside I noticed that all the black (old neutral) wires were wired together in a terminal block, and the red, blue and yellow wires were connected to the switch. Nothing was...
