Help.. no lights downstairs in my home

[jrt]

Hope someone can please help with strange (to me) issue

I turned lights in last night in my home & they came on & then went off. But all apart from 1 light downstairs in my house doesn't work. At first I thought fuse, but it's ok. The 1 light that stays on is on same fuse as the ones that won't. None are linked with same switch so none of the lounge, kitchen, dining room, hall or lower toilet are working. Any ideas on where to start to remedy ?

Thanks

If your single switches only have two wires present, ignoring the earth the problem is not likely to be at the switches but at the light fittings themselves where the lives and neutrals loop through.

OK thanks, I will run through them all, damn, a lot of them

Morning, thanks for all the comments. I have a switchbox (not breaker) that has fuses in it that has 5 fuses in it, 2 for lights (up/down) 2 for sockets (U/D) & 1 for the cooker. If I swap the fuses for lights, all still work upstairs so thats how I know fuses ok. The light that works is not closest to fuse box. FB is in a converted garage & the light in that room does not work, in fact, I would say only light that does work is furthest from the FB. Nearly all my lights downstairs are spotlights, I think maybe a loop issue somewhere ? PS: I am in the UK

"If I swap the fuses for lights all still work" are you just swapping the upstairs and downstairs over, have you actually checked to see if the fuse on the circuit that isn't working is OK? Your original post seems to intimate that all the lights are on 1 fuse, in your last post you say you have 2 fuses 1 for up and 1 for down 99% sure 1 of the fuses has blown, time to get your tools out and check the fuses out.

2 fuses, A - Downstairs, B Upstairs. 1 light from A working, all from B working. If I remove fuse B & put in Fuse A slot & A into B, then same result, all up ok, only 1 from down working.
I have now dropped down 20 spotlights & checked all wiring, all ok & tight. I have checked 4 ceiling lights, all ok & tight. I have removed 4 light bulbs, all ok & work in lamps. Nothing on the face of it is wrong, everything "should" work. I have a friend who is going to lend me a multi-meter in a couple of hours, that I suppose is best way to check if I am getting feed ?

If fuse had blown, I would be able to swap them over. I have tried with just 1 fuse in, swapping them over, same result whatever I do

you need to do dead test continuity on L, N ( and E ). this would entail using a wander lead.

You must take care when working /testing on live circuits, especially with a borrowed DIY meter, which I presume what your Friend is, a DIYer.
Test leads need to be up to an industry standard, which your borrowed meter may not conform to, this in its self could be dangerous, I would seriously think again before attempting this, do yourself a big favour and get some professional help, call an Electrician.

And test equipment

OP, you may well have an under floor junction box or boxes that have gone faulty, think it's time to bite the bullet and call an Electrician. Hit & miss fault finding rarely works and can introduce more faults.

No: The best & safest way now is to call a sparky, if you find no feed at some point would you know how to actually locate the fault ?. I'm all for DIY but also for people knowing their limits.

Hi could be first light is to a wc/bathroom with a fused spur for fan overrun and wired on wrong side. Worth checking all the 3a fuses. Had similar problem stumped me for a couple of min's MCB tripped but nothing came on afterwards.

 

[jrt]

No fan, so not that but thanks anyway. I cant fathom it out, will try & get a sparky tomorrow

 

[Pete999]

Crikey are we still faffing about with this could have driven down to the OPs gaff sorted the fault and eating a Big Mac on the Motorway by now, on me way home.
