I've removed a ceiling light fitting in the bathroom of my 'new' (built c.1960) house, and I'm a little confused by the wiring - perhaps someone can suggest what is going on -
The ceiling light fitting has three terminals, of which one is not used and the other two have black wires running to them - one each. The two red wires are joined together and insulation taped. The two earths are also twisted together.
The light works fine and switches on and off with a pull-cord switch located elsewhere in the room.
The problem is, the light fitting I am replacing it with has a Live and Neutral side, and I don't know which wires to put in each side - I tried the two blacks, one in each side (as per the current light), nothing happens - then tried the two blacks in one side and the two reds in the other - the light comes on, but permanently on irrespective of the switch position.
Any suggestions gratefully received.
Cheers, D.
