[QUOTE="Doc Hudson, post: 494867, member: 1607"] Has it ever worked correctly, and/or has someone replaced any of the switches that control this light in the recent past? If it has never worked it is possible that has just never been connected correctly, or it may be that when originally wired someone forgot to put in adequate cables to allow full intermediate switching. To verify exactly where things should go, you do really need to test the continuity between the switches to identify exactly which wires go where. Also you need a suitable voltage testing device so you can confirm where the supply live comes in and the switched live goes out to the lamp. The basic concept of intermediate switching is as per this image. [ATTACH]10493._xfImport[/ATTACH] Doc H. [/QUOTE]
