The touch lights above the sink have stopped working. I’ve checked the lamps and they work in other locations. Tested to lamp socket and no current. Dismantled various panels to acces wiring and nearest circuit has power. However I can’t get access to the lamp wiring behind the fascia in the cupboard so can’t see the connection between the lamp wires and the circuit it feeds off. I think I’d need to take the above sink cupboard off the wall to access the wiring.

Has anyone a better suggestion?

Also there doesn’t seems to be a detailed wiring diagram. Does anyone have one or at least a guide to the various wiring colours?

Thanks for any help,

Brian

Following advice from similar threads on book face, try giving them a good wipe over; they sometimes get greasy and it affects the switching function.
You’d expect the kitchen ones to suffer most.
