Lord Geordie Posted May 26, 2018 Report Share Posted May 26, 2018 (edited) I had a rewire done a few year back, yesterday I blew a LED bulb at the top of the stairs. Strange part was it wasn't on? The light has three switches to it! One at each end of the upper landing. One downstairs. So I put a fluorescent energy bulb in last night. Tonight I notice it flash once every 2-3 seconds, just a brief flash. If I then switch it on with one switch then off at another it stops, say I switch it on down stairs and off upstairs, if it flashes, I switch it back on at the switch I switched it off at, then use the other upper switch to turn it off, and it stops flashing? It's doing my head in. Edited May 26, 2018 by Lord Geordie Quote Link to comment Share on other sites More sharing options...
Ricko Posted May 27, 2018 Report Share Posted May 27, 2018 Have you tried the energy bulb in another fitting elsewhere in the house to see if it flickers? Quote Link to comment Share on other sites More sharing options...
Lord Geordie Posted May 27, 2018 Author Report Share Posted May 27, 2018 Yes! It is solely that one light fitting fed by three switches! If there is a constant low voltage even when switched off before I change the off switch pattern? It's almost like there is some form of power bleed into the system! I just need to try and find out from where? And how to remedy it! i am going to try changing the switches one at a time to see if that helps. But I feel it's more a leakage of some sort through the ground wire? Quote Link to comment Share on other sites More sharing options...
ph5172 Posted May 27, 2018 Report Share Posted May 27, 2018 I was about to say how about trying as single switch. That or look at the voltage on each line to see what’s what Quote Link to comment Share on other sites More sharing options...
Remimax Posted May 27, 2018 Report Share Posted May 27, 2018 had this fault few months back ,customer had a flashing landing light which had 3 way switching. when tested one of the 2 way switches was faulty. Quote Link to comment Share on other sites More sharing options...
Lord Geordie Posted May 27, 2018 Author Report Share Posted May 27, 2018 Thanks guys! Will swap out switches first! If I get the same will then delve deeper into voltages and possible grounding issues! Quote Link to comment Share on other sites More sharing options...
Wiggum Posted May 28, 2018 Report Share Posted May 28, 2018 Sounds like you have two 2 way switches and an intermediate switch on the lighting circuit but it would be a good idea to unscrew the switch’s and check before you purchase replacements Quote Link to comment Share on other sites More sharing options...
