Ok i have a 1940's built house the sockets are same age as home im guessing im replacing the sockets with nice 3 way lights did one socket np next one i pulled from out the cieling and noticed it had 3 prongs at the wiring end 3 red wires 4 black wires now im sure 1 of the black wires went to a 3rd prong and screw thought it was N A and Earth.
so i conected it all up using the 3 blacks wires to and red wires and then put the earth which i thought was to the earth on the new lights.
when i put it the new 3 way lights on and plug them all up they worked np though they dont turn off they are constantly on.
when that happened i turned it all off again and cut the earth wire fronm the new lights tried again same thing.
Somewhere in there there is a constant Active wire maybe having so many wires it could be in a loop or switch wire i shooked up wrong i dont know.
Im new to all this stuff and learning as i go or off what my old man knowes and he was stumped any help will be much appreciated.
