I'm replacing some old switches on the hall/landing. 1 gang 2 way upstairs, 2 gang 2 way downstairs. I'm having trouble even after I've followed the diagrams on the how to section. The house is from the 70's so I presume all the wiring colours are old too.
Upstairs switch has 3 wires (Earth, red, black with red sleeve) coming from above which I presume goes to the light, and 4 (Yellow, blue, red, earth) coming from below. I've wired it as follows, in common is red from below, L1 blue and red, L2 yellow and black with red sleeve.
Downstairs has 2 choc blocks (obviously has two switches) first one has red in common and black with red sleeve in L1, and second has red in common blue in L1 and yellow in L2.
Nothing happens with power and no doubt I've made a huge balls up, I've never done this kind of thing before and I'm struggling. Any advice is greatly appreciated. Thanks
