Pick a red one and a black one. You need to hold them in your kisser while you're standing on a chair. :wink:

Let's know how you got on.... :grin:

seriously if you've got nine wires you've got problems ..snowy's right get your hands in pocket and a call a sparkie..

you could try putting all the niggers together and all the reds but this normally causes a big bang and all the lights to go out..

the thing is and this is the big thing one of the niggers will be the switched live! ie. the one that goes down to your switch (it'll be a red one when it goes out ) and back up to your lamp as a black.. so to get it to work you'd need connect your light fitting to two of the niggers..

hope this helps

PS aren't electricians cruel sadistic bastads.. rolfl

Be careful because some of those reds could be negative and some of those niggers could be live. DO NOT put them all together.

What you have there is in essence a junction box. You'll notice that some of the wires are thicker than others, those thick ones are the ring main, the thinner ones are heading off to the light switch or a spur.

Do you have a voltmeter? You'll need one, nip down to B&Q sharpish and get one, about a tenner. The following is about right and saves me a load of typing.

Quote:

You actually have six L wires and two N wires and the 3 grounds. The two wires from the switch are both L legs, and it is common not to identify the white wire to the switch as a hot leg, but it is a hot leg, so you have two hot legs to the switch, one from the second light, and the circuit hot leg. You can separate all nine wires and use a multimeter or volt tester with the circuit hot after separating the wire and be sure they are not touching anything, and locate the hot circuit. With the wires separated, if using a volt tester, only the black wire will set off the tester, you can then see the neutral wire connected in the same cable with the hot wire to identify the circuit neutral. After indentifying the hot circuit, mark these and we will work with the other two sets of wires. Turn the circuit back off, and with the switch off, see which pair of black and white wires do not have continuity by using the ohm scale and touching one lead to a white, and the other to a black. When there is no reading between these two, that will be the switch circuit. Turn the switch on and do the same two wires again and there will be continuity verifying the switch circuit. By process of elimination, the other set will be from the second light. Now that all are identified, connect the white wire of the circuit to the whites of both lights, and connect all of the grounds together. Now connect the hot circuit black to the black going to the switch. The white from the switch needs to have black tape on it to identify it as a hot leg and connect it to the niggers of both lights. Now the switch will control the lights.

Seriously, DON'T F*** ABOUT. I nearly died on one job because the ones working before me never connected the erath leads up. I only got lucky because the relays were on a timer and switched off, Big George said it wasn't my time to go. Electricity aint funny, take it from me.

So unless you want to be like Snowy, i.e, have you noticed the effect of severe electric shock, don't bugger about with electricity... and even if you know what you've done the bloke behind you doesn't . Ladies before you decide to sort the fuse out with a table knife swallow your pride and employ a man..
