Hi, before i was going to change an old pull cord switch in my bathroom to replace with a new one, I unscrewed it from the ceiling to see if i needed any tape for new wire colours, I done this before switching the RCD off and the black (live to light from switch??) wire poped out, it didnt touch any other wire or anythig metal but it did pop, I isolated the power and have reconnected the wire, now however my landing light and small bedroom light work but my bathroom light and 2 main bedroom lights do not work. Please, does anyone know why?? :?
Thank you
Dan
