Hello all Im new here. And was hoping to pick some brains. I am renovating a bungalow and have knocked the toilet/bathroom into 1 room. I had 2 light circuits so I have extended one into the centre of the room as the bathroom light and extended the other into the loft. By extended I mean I have put them both into junction boxs because the wires were not long enough for the new locations. Everthing worked fine for a couple of weeks but today neither would come on, They glow a little and flicker but dont fully come on (bathroom is a halogen fitting and loft is energy saving bulb). All the other lights are fine. I have opened the junction boxs and given all the wires a tug to check they were tight. I also did some tests with my multimeter and I am only getting 170V. Any ideas?
