Advice Needed - Lights blown after fitting

Paul Haynes · Nov 21, 2018

First off I'll say I'm not an electrician at all, I'm just a guy who bought a house and tried to fit new lights in the hallway. So I found that out of the two light sockets, one had the usual three wires (blue, brown and yellow/green) whilst the other had two of each of those wires, so 6 in total. I fitted both lights, but on the second one (with the 6 wires) I put two wires into each connector, without knowing any better. The lights worked for a few days, then one day I turned them on and there was a pop and they went off. The light switch I used has now fused (I think), basically it won't flick on and off anymore, it's just stuck. So I was going to call an electrician but in an attempt to save some money, is there an easy fix here, or an obvious reason as to what went wrong? I spoke to a friend who knows a bit about this and he suggested maybe I shouldn't have put two of each wire into the second light, and that some of those wires should have been marked up in some way (they weren't, beyond having two blue, two brown and two yellow/green).

Thanks for any advice

If they worked once you'd completed the change over, it's likely that the failure is not your fault and from the sounds of it is more likely to be a result of a failure in the light itself. Are they low voltage lamps?

Don't suppose you have any photos of the before and after wiring?

Either that or you didn't make a great job of connecting them, a cable has come loose and shorted out.

My advice would be to engage the services of a local electrician (preferably based on a recommendation from family, friends or colleagues). It sounds to me like it might be a simple enough task to fix it up and if you phoned me asking about this I'd probably quote you an hour of my time to investigate the fault.

Welcome to the forum mate.
It does sound like the second light that has two cables toing to it is your problem.
Without checking, I would guess that one of the cables is for the power and the other is a cable going to the light switch.

I'm afraid I don't have any shots but I can disconnect this weekend potentially and take some if necessary. I got these bulbs, not sure if low voltage or not. The light fixtures are from Next, and each takes 3 of these bulbs:

Hi, and thanks. So I don't quite follow - there were 6 exposed wires in total, are you saying that only one of each of these was intended for the light, and the others are just to be taped up?

Hi Paul,
Please ignore my post above. If you connected like-for-like coloured cables together and the light were working then I'd go with @SparkyChick post above.

What I mean by 1 cable is this below. 1 cable = 3 cores or 3 wires

No problem, thanks. I have an electrician coming on Thursday next week but he wanted £60 for the hour. Maybe that's reasonable, just wanted to check if this is something I could easily fix myself first

May have screwed through a cable which didn't immediately create a short but it has now.

I suppose I could test this if I re-connect the original hallway light. I assume if that still works then the wiring is ok, and maybe it was the fault of the new light?

Taking photos now probably wont help, it is a shame you didn't take a photo before you took the old lights down, I have an idea what could be wrong but it could be exactly as sparky chick has said, unfortunately as we didn't know what the connections were before guessing is not an option. I hate this sentence but "Get a Spark in"

Paul Haynes · Nov 21, 2018

Alright, thanks for the help guys!

£60 is a bit on the high side for a call out, but not unreasonable. up here we lucky to get away with £40.

Don't forget to lick your fingers before you test.....
Joking aside, it's not just a case of something operating or not, the safety aspect is even more important.
For the sake of a few quid call a local electrician whose qualified and could deal with the problem safely and quickly.
edit. Already done, I see.
