I have a strange issue with a light...
A friend has a double pendant main light that takes little bulbs (240v), they kept blowing, and instead of replacing with filament we decided to go LED. We sourced some and they work fine. However they never quite go out, and always have a glow, never fully going off.
So out came the screw driver... The wiring and light switches are pretty simple, a feed supply that goes straight back to the switch board, a loop to another switch for two way switching and a feed up to the light. All the wiring checks out with earths, neutral and phases etc all fine as I have checked these, for continuity and any shorts etc (including a mega) all check out fine and all are correctly wired/terminated.
Now this is where things get interesting. If I disconnect the feed wire (from the switch board) the glowing stops, as you would expect. If I remove the wiring going over to the two way switch and wire directly from the switch board feed to the light the glow stops and everything works as expected. If I then use the loop wire over to the other switch to act as a loop for phase (not two way switching) the glowing occurs.
Basically if I run power through the loop cable thats used for the two way switching the glowing occurs, it like the cable is inducting from somewhere, yet with the cable disconnected there is no voltage present, or resistance present etc etc.
Of course this glow doesn't happen with the filament bulbs as they need so much more current to glow....
I am so confused... any ideas?
