The corrosion may well be the problem. Corroded termionations make bad connections.I agree about the corrosion, I shall replace the fitting once I figure out the issues I am having with the light
I completely forgot that after the power cut the bottom switch had some browning so I replaced it before using it again.
Almost, the reds should be in loop and the earths in E. As the E in those type of fittings is also insulated I doubt it will make much of a difference electrically, just an observation., is the lighting in the rose correct as far as can be seen?
