I had an old grubby light fitted to the outside of my house. Not a security light just a normal light. I’m after fitting a new light to it, the light had a bulb holder style bit for wiring the live and neutral into (black neutral white live) no were for earth to go so put earth into terminal block with insulation tape around it. Problem is soon as I’ve put power back on the light isn’t going out or switching of at what I’m assuming is the switch for the light as it’s directly below it on the inside of house, can anyone help please
