Lighting in one room

[trigg3r]

Hi all,

Hopefully someone can help me out here, as this is a strange one.

In an upper floor flat, the bedroom light has just stopped working, it's never had any problems before and suddenly it just doesn't switch on at all.

I've checked the switch and replaced it, which hasn't helped. I've tried replacing the light pendant, but that also didn't work. I've been up the attic and checked the junction box for that light and all looks ok, with the exception of the earth wires not being tightly 'twisted' which has now been resolved but hasn't fixed the mystery of the light not working.

Has anyone any ideas on what could be wrong here, I'm so confused as to why it's suddenly stopped working.

Any help appreciated.

Cheers,

Trigg3r

Welcome aboard.

You`ll find that we need a bit more info to diagnose the problem - if it isn`t the lamp, pendant or switch, and all other lights on the circuit work, you need test equipment to verify continuity of various conductors before any progress can be made.

Maybe time to call in a sparkie ?:|

Yeah, no problem, I'll get a sparkie in, just wondered what it was and see if it was something silly that we could have fixed ourselves.

Hello and welcome to the forum.

Firstly there are many reasons why anything that worked before is not working now, all these reasons can be solved by the use of test equipment, and of course experiance. Without either it is almost impossible over a forum to give you a correct answer and solution. We would need to know R1+R2 readings Insulation restistance across L+N L+E and N+E, loop or Zs, and Ze.

Most faults can be put down to faulty connections, often on old installs you find guilotened cables, caused by overtightening on the terminals resulting in a none connection even though the cable looks like it is secure, its not actually connected.

An electrician would do a methodical test procedure which would identify the fault and then rectify it.

q1

If you have checked the switch...

Why did you replace it? was it faulty?

If not faulty. why did you replace it?

q2

You tried replacing the pendant? does that mean you did or you didn't?

q3

What does a good junction box look like?

I haven't found any electrical connection I can prove just by looking at it?

What voltages are you getting the terminal?

Have you REPLACED the lamp????

Most likely the live feed at the PREVIOUS light in the circuit..

i.e. a light that IS working, but the outgoing supply from that light is open circuit!

P.S.

Welcome to the forum

just take a quick look in the previous light, as you think it may be wired, or other lights nearby? you may have a broken live or neutral.

I think someone qualified really needs to have a look at the circuit if the earth wires are just "twisted" together.

Welcome to the forum Trigg3r, as has been suggested already, a competent person with suitable test equipment should be able to identify the cause of your problem reasonably quickly. But you do need some test readings from the cables, also you need to know if the lighting is looped at the fittings or the switches or boxes, or mixture. It can be very difficult identifying cables without a test meter, such as where black wires have been used as switched live's but not sleeved or marked, leaving confusion with correct black neutrals. Unless you can post some photographs, its very difficult to offer any more help. Remember you could have a broken live or neutral somewhere on the circuit, have you considered rodent damage? any mice, rats, squirrels evident around the property. I think you need an experienced person to have a proper look.

Sounds like an old flat, wired in the 1960's where it was common for all lighting to go to one big junction box, and common for all the bare earth wires to be just twisted together, often outside the junction box.

Perhaps the whole junction box is wired with twisted wires in screwits.

As the others have said and this is not putting you down, an electrician will test the circuit concerned to find the fault as it requires the use of testing equipment. This shouldn't take too long as it's usually done in a methodical way. Any other concerns the sparks has about anything else he/she finds will be noted to you. It's their professional opinion!
