Light removed but problem?
Hello all
Ok I have a small problem but I wish to understand it further.
A mates house has a dining area with some old lights in the ceiling, if I remove these lights from the circuit by removing the wires coming from the light fittings only then the laundrette lights next door do not work.
Now I guess the guy who fitted these light has come off these lights somehow but I need some advice on how this guy has most likely wired this. Its about 8 years old.
Has he run one HOT wire through the existing lights to the laundrette and by removing them I have open ends somewhere? any help would be very much appreciated. I'm very sharp on most things but I need a little help on this one.
thanks
Phil

This circuit was part of an extension to the house. The box for the house is front with dining area middle and laundrette to the rear of the house, so it's likely the laundrette is last in the chain.

Hello and thanks for the reply,
I'm sorry I could not come back sooner as I had to go back to my mates house to check. Unfortunately the lights had been binned, however I have taken details and I will try to explain.
The House had an extension put on some years ago, this consisted of a dining area and a laundrette. I have a picture ive fumbled together to help.

In the dining room there were two spot lights and one centre light, these were decrepit and needed replacing. The idea was to remove the two spots and replace the fittings in the centre so it could be used.
When I investigated the wiring behind the 2 spot roses, there was three connectors (screw type in plastic block) I have listed them as follows.
The list below does not count the actual lights wires, listed below are the wires coming from inside the ceiling into the connector blocks.
OLD LIGHT REMOVED ONE
pin 1 - 2 x Black wires
pin 2 - 2 x Earth or copper wires
pin 3 - 1 x Black wire
OLD LIGHT REMOVED TWO
pin 1 - 2 x Black wires
pin 2 - 3 x Earth or copper wires
pin 3 - 1 x Black wire
plus 2 x red wires twisted together and taped.
So the plan was to remove the two spots by lifting out their Live and Neutral wires, then replace exactly the Centre light so it could be used.
On the wall in the dining room is a switch SW1 with two switches on the face. One controls the Centre and presumably the two spots however I cannot confirm this as they were not working when started. The other switches the Laundrette light.
The other switch SW2 switches the laundrette light on or off.
After the two spots were removed and the centre rose replaced I checked the wires I had added (2) and made safe.
The problem . . . .
The laundrette light switch from the dining room does not operate the laundrette light anymore AND if you switch the laundrette light switch SW2 to the ON position, then you cannot switch the Centre Light off in the dining room?
Any help on this would be much appreciated, I figured the spots would have been looped of the live and removal would not have caused any problems, pheeemph!.
Reading up only says it depends how the wiring was done and without ripping loads of floorboards up, no it doesn't bear thinking about!

Phil,
You would be better served by someone familiar with UK wiring.
When you removed the old light, did you leave all the wires feeding it connected exactly as they were? Did you connect up the new light exactly as the old light was connected?

All I have changed is the live and earth of the spots was removed. I have changed nothing else, the live and earth was removed from the centre and a new centre light was added where the old wires came from!???
If that cannot cause this then its likely I may have disturbed a wire.
Do you have a link for a uk forum for me to get some help with this.
I really never expected any problems in a simple removal hence I went ahead!

I cannot understand what you want to do so I will keep things general.
Construct a setup of what you want to achieve on a workshop bench, say 2 switches and 2 lights which you can test with a cheap multimeter. When you get this working then try to relate it to the real thing, this may help you see where the problem is. For your test setup you don't even need to connect the power so that keeps things safe.
