Feels like this is something of a lost cause. I can't seem to identify a switch wire on the upstairs wiring, they are all just black. At this point i'm just trying random permutations and hoping I get lucky.
ok, will do.
but assuming i've done that and I know exactly which wire is which. What is the correct setup for the switch? In terms of Live to Com, Neutral to L1, switch to L2, etc...
i've got an upstairs and downstairs fuse...but both these lights are on the upstairs fuse. Despite one being at the bottom of the stairs.
as to the neutrals. I have three black sheathed wires, although one of them has a small section of red sheath at the connection point. Bearing in mind...
I'll start by saying...help i'm desperate!
I'm a complete amateur here and i've inherited a problem I don't fully understand, which is causing me some annoyance.
so, the situation is that I have a light at the top and bottom of the stairs and a double switch at the bottom and on...
