Morning all, just wondered before I call in the professionals if anyone could shed any light on the below.

Pendant Celling light in sons bedroom is not coming on. So I expect it is just the bulb, which I try 2/3 different bulbs to see, still nothing.

Then assume that switch may of broken so check for loose wires and still nothing. Change switch to another one and still nothing.

The room is at the back of the house on a loop with just the bathroom (which is working) so assume it cannot be fuse or broken wire in the loft.

I have unscrewed the pendent cover and nothing looks to be loose but have not changed this yet.

If anyone has any ideas on this it would be much appreciated?

The wiring is current and was only changed in the house circa 5 years ago if that helps.

If its a pendant then the dangling wire could be dodgy. Seen that a couple of times. I'd try changing that as its a 5 min job (although probably just as eay to change the whole pendant).

I am thinking the pendant might be at fault as often teddy bears are chucked about etc. hitting the light.

Just wondering if I was missing something here!!

Electricity is one of those things where if you need advice you really shouldn't be going near it.

Not being awkward, being safe.

Over reaction of the day!

If he's isolating the lighting circuit and replacing like for like based on advice as to what the faulty part may be then there's no issues at all.

RegP, have you hung any pictures up or shelves recently in/around that room? If you have a multimeter or voltstick, then at least you can check your terminals at the ceiling rose and switch.

Get yourself an electricians screwdriver with a test light in it & test the terminals / junctions in the ceiling rose / light switch for a live. Then the contacts in the bulb holder. You should be able to work out if/where there is a break.

Check the connections in the bedroom ceiling rose first. Changing the bulb will not confirm that there is power getting to the actual fitting at the end of the cable. The fault may be at the rose (check both connections are secure). It also may be at the bit in which the bulb is put into - check the connections there too.

If you don't have a multimeter or voltstick then get a cheap pendant set from the corner shop, take the flex/lampholder off it and swop with the existing one.

If this is ok then step 2:

Lighting is almost always run as a radial circuit. It will therefore be fed from a junction somewhere; quite often in another light fitting. (This is called "loop in" wiring).

It is preferable to trace the wiring back from the bedroom so if it's possible to do that in the loftspace that would be good.

If not, I would take a look in the bathroom light fitting. If it is a simple pendant then I would be looking to see if one of the wires has come out from one of the middle set of connectors - these are the loop bit - there are usually three in there - the live in, the live to the next pendant and the live to the switch. It may be that one of those has come loose.

However, with bathroom lights it's often the case that the fitting is a fancy one that isn't compatible with a ceiling rose and the installer has had to do some "mods" to make it work. Some mods are better done than others and it could be that when you take it apart you'll find a number of "chocblock" connectors, either in the fitting or maybe stuffed above the ceiling. It may be that one of these was not properly tightened and has come loose.

Remember that these will be live even with the switch off so isolate the supply. A proper safe isolation procedure is recommended but if you are in any doubt use the Big Red Switch to turn off the whole installation.

Rich.
