Not sure if this belongs in this section (or indeed any section here) but I'm sure that if I'm in the wrong place one of our lovely MODs will move it
I really need some advice from a friendly electrician if there are any here.
I am trying to help a mate who is having some problems with ceiling lights in his house. He is replacing two existing light fittings (which both worked) with two new light fittings. The first went without a hitch but unfortunately the labels that he had put on the wires of the second one fell off half way through and now we don't know which wires go in where.
I've had a little experience with lighting circuits and (as far as I can see) we have got both fittings wired correctly but for some reason only one of them is working.
We have swapped the fittings around (just in case one of them was dodgy) and they both work but only when wired into the one (working) location.
If I post a diagram of what we have (and what we know about the wirning) could somebody qualified take a look at it for me and make some suggestions about where we've gone wrong please?
I'm sure we've missed something obvious (and probably stupidly simple) but I'm totall stumped!
