I have just changed a ceiling light fitting and have no power to light. 2 cables from roof containing live, switched live and 2 neutral.Cannot remember how light was wired previously as it was disconnecte some time ago and I did not make a wiring diagram. This fitting is end of loop light but cannot remember whether light is connected to switch live or live. I see 2 live cables were twisted together but cannot remember if switch live was in same connector block as live cables. Any help appreciated as to whether live and switched live are twisted together and then light live will be connected to live/switched live .
