I'm trying to change the security light on the external wall of the front of the house. The previous one the sensor shorted. So bought one from B and Q and installed it. Old wire colours. Black, Reddy/Brown and uncovered. So put Black to Blue, Reddy Brown to Brown and uncovered to Yellow/Green. Still down't work.
Have bought a little power tester (one of the ones that look like a little screw driver) and it's telling me that power is getting to the light. (Have touched all wires from wall socket and all light up except the Black. Is this normal? Then touching the wires going into the light all light up.
Am I being a numpty here? I'm assuming I'm doing something wrong or the light just doesn't work.
Can anyone help me??????????????
