Had the ceiling skimmed and so lowered the light. The light has now stopped working, if the light fitting is disconnected and I test the cables for power it is there and shows 110v. If I then connect the light fitting and test the connections it shows no power at all. It's very puzzling as I've tried 2 different light fittings and nothing. Any help would be appreciated. Cheers PS: The wiring has not been altered at all from when the light worked.
