hi, can't suss this, doing an extractor with run on timer, which has led light. Cabled the separate isolation switch, two way to fan, 2 way to jb, light switch l1 to isolator l1 at jb, sperate line feeds to lights, common to line at jb with live feed from lighting ring, neutral has neutral in and and out for lighting circuit, 2 lights out, neutral from isolator in. Test it and nothing on switching on, there is power in ok but both lights out and fan, nothing, can't see anything wrong with wiring, any suggestions other than give up and go for a pint!
