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

Junction box in garage which is converted to an office now (man cave) JB was tested, all working fine, still only 1 hall light working, this light "could" be first on circuit, but sparky had no clue which light was next as all other lights are dead

Flat light as in not a pendant, close to ceiling no rose or hanging cables

Batton holder then

no, like this

cutting holesin ceiling seems a bit drastic. can't boards be lifted upstairs?

 

[telectrix]

no, like this

dome light or U>F>O.

well my fault is out of this world, so I will go with UFO lol

If issue is in lounge, I can cut out flooring upstairs, but its been working for 3 years, so I have to presume the latest install, being the Kitchen is the fault, but above that, is my bathroom & I have marble floor tiles in there

Yes. I love these kind of sparks! Keep us updated!!

Don't let him cut holes.
If he has to make holes then tell him to use a 4 inch hole cutter ( enough to get your arm in)and to save the bits he drills out so they can be used to patch the holes up

Think I'm gonna do it myself, I have a hole cutter

You sure that's only whisky in that tea ?.

It's OK it's the magic roundabout Tel's on, not the magic mushrooms

Im only an amateur diy'er with an interest in electrics but I think I must be missing something here so im happy to be corrected by the forum professional's.

If this was my house then the first thing i would do would be to trace the live loop/radial to see where or if it fails.

Im assuming you know how a basic lighting circuit is wired with the permanent lives (in series/loop/radial circuit with no return leg to the consumer like a socket ring) and switched lives?

As already mentioned regarding the 1 working light, have you pulled all the other fuses to be 100% sure it is fed from the downstairs circuit?


I take it you have so next I would drop the light fitting that is working and check that I had a live loop entering and leaving that fitting using my voltage detector pen. If it doesnt then its a bad connection at that fitting. If it does then I would then check the other fittings to see if there is a live there. If I couldnt find a live at any other fitting then i would know my problem is with the cable leaving the working light and I would trace that cable as it is that or a joint in it that is breaking the loop.

As said im only a diy'er but i successfully mananged to solve issues in my own property using the above logical approach.

I know i havent mentioned neutrals but I would check the live first.

logical approach, but i'd not rely on a voltstick. using an approved 2 lead voltage tester and measuring both L-N and L-E at each light would verify whether it was the L or the N that was at fault.

Fair comment but ive not got one lol. I would like to learn how to use and understand test equipment though. At least you didnt slate my diy'er with no proper equipment approach.
