single black wire on light fitting Ask questions and find answers to many subjects relating to electrics and electrical work

Hey guys, just replaced a light fitting (stupidly without noting down what the original set up was - blame the other half for chatting to me at the same time :wink: ) and can only get the new light to be always on, i.e. switch not working.

There is a single black cable and 2 sets of red, black and green. At the moment i have 2 reds and single black to live (brown), and 2 blacks to neutral (blue). Tried a few other combinations without any luck.

Any ideas which should go where please, all help appreciated as im starting to get nagged by the wife lol...

Cheers.

Hi, take the reds of the fitting flex & put into seperate chock block, put single 'blk' into fittings live, the rest are right

Heya, thanks for the reply, tried that combination last night, but no power. Would it have anything to do with it being a ceiling fan with a light that has its own on/off switches? Got a dimmer switch on the wall as well, that i guess would just turn on the power to enable the on/off for the fan?

Anyway, tried every combination of blacks while the 2 reds are connected to each other in their own block but no luck. Also tried every combination of blacks connected to each other and reds in neutral and live - therefore tried all combinations other than mixing reds with blacks. Yep, spent 4 hours on it last night on it, think ill have to bring the hammer on it tonight :)

Any other ideas i could try later please?

Cheers.

Hi you never mentioned the fan!
suggest replace dimmer with normal sw first as too many unknowns/variables, fan may only work on pull cord on it & other sw. wire may do light, one thing at a time!
