[QUOTE="Evans Electric, post: 391363, member: 1408"] Yes as Noz says , one of your blacks is the switched wire coming up from the switch . Thats the one that works your light & needs to be marked so you don't mix it with the other blacks which are neutrals . To answer your question , very few older installations have the cables marked. Often too, the fuseboards were never labled up either. Sorry you're in the dark but its difficult for us without being there . There are things you could try but we can't recommend working live . You could rig up a simple tester with a battery and a torch bulb ,say, to find the cable to the switch , but you MUST SWITCH OFF the power first . [/QUOTE]
