I put new spotlights in my BEDroom and when i turned on the bathroom light the shaver and main bathroom light went, ive changed the bulb 4 times, changed the main bathroom light, changed the wall switch, changed my bedroom light and still my bathroom and shaver will not come on, whats happened? I cant figure it out. THEN>> So then I got a brand new light fitting and changed it in the bathroom then all the lights went in the house, and when I press the fuse box on it flashes and goes back to off, so now all lights are off. All I can think is I toughed onto the bathroom light to cut cleaner wire I might have damaged the wire. 3hours later Electrician has just gone, fault not fixed, turns out it wasn't to do with me fixing the light. He disconnected all the first floor switches but still no power goes to any light. He said theres a live to earth fault somewhere in the wires. I'm guessing it must be the bathroom wires. Although all the lights and switches where disconnected so he said it cant be the bathroom wires. ?!?!? I take it this is a hard fault to find? Charges £12.50 per hour that ok?
