Hi there,
There are 4 lights which are relevant to this problem, and one of them (LIGHT A) was on a 2 way circuit. I have changed a 2 gang switch (labelled SWITCH B) to a dimmer switch which is 1 gang only (labelled SWITCH C) and made the changes on the diagram.
I reckon SWITCH A was wired inappropriately as it would switch both LIGHT A and LIGHT B, and was 2 way with one of the switches on SWITCH B, which would control LIGHT A. The thing is, LIGHT A is an outside front porch light, so to my mind it doesn't make sense to have that being switched from just outside the door, and from the main inner hallway? Could it be the person who made changes to the switch, put the wrong blue and yellow wires to the wrong "switch" in the 2 gang "switch unit", meaning the wrong light was being controlled by the secondary of the two way switches (God I hope this makes sense!)?
Anyway, the big problem I'm having now, is that LIGHT D will not come on, if LIGHT A is switched on! LIGHT D is in another room altogether, and on a 1 way circuit?
Any help appreciated if you can help me see whats gone wrong!
Thanks in advance
