BATHROOM LIGHTS NOT WORKING...HELP

[dude_diy]

Many thanks in advance for any help and advice people post...

Basically down stairs bathroom light have went they just now wont come on ( all other house electrics are fine ) The lights fitted are small down lights which take a 10w capsule bulb. There's 10 lights in total, zone 2. They run off a transformer as well.

I would like to know if i may need to replace the transformer or is it likely all the bulbs have went?
One bulb did go the other day, which i took out meaning to replace it but forgot. Could this of coursed all the lights to go? Because they had been running with one lamp missing.
The transformer is behind the plaster board ceiling and would mean more of a carry on, cutting into ceiling.


ive hopefully attached some images as well.

Thanks again really appreciate any advice

You really must make sure that the transformer is in an accessible place, and looking at your picture that could be easy.

Assuming you have power to the transformer, and all connections are sound, it sounds like the transformer is knackered.

Make sure you get the right transformer.

Where the lights working before you rewired (repositioned) them?

Do you have acccess to and can you use a multimeter?

That transformer is going to be boxed in by the looks of it - not a good idea - especially if it expires - like this one may have now.

Is that a backbox for a double socket on the right of picture 1?

I thought it was a glass block.

I thought it was a glass block.

Could well be - my eyes are probably playing up because I was trying to read the instructions for the lights (?) attached to the left hand side of the door frame..... Either that or its a notice to quit

dude - you need to get hold of the clown who installed those lights (he's the one who told you that he was an electrician), tell him he's sacked, and get someone who knows what he's doing.

There are at least two contraventions of the Wiring Regulations visible in that photo, which makes me wonder

a) What other cock-ups he's made.

b) How he's going to claim compliance with the Building Regulations.

Talking of which, I wonder how he thought that swiss-cheese ceiling would manage to comply with Part C?

thanks for all the replies, the pictures are old now, and the ceiling has been plastered painted etc. lights have been working fine for 3 years and just gone now.

thankfully its not not a double socket in the bathroom, and we decided against the glass blocks.

cant use a multimeter and don't have a much of clue about electrics, but im confident enough to put a small access hatch in the ceiling and to change the transformer.

I will look into changing the transformer and work from there. thanks

If all the rest of the lights are working and that circuit is part of the lighting circuit, chances are it is the trany.
But I would still want to test it out first.
You can buy a multimeter for a £10, that will include instructions.

Just to add the fan in the bathroom still works off the same switch. If i turn the light switch on the lights stays off but the fan works...could that point more to the transformer???

Reading the original post, it sounds like the bathroom is now complete, and the pictures are from a build log or something.

I bet it's your transformer, so get cutting into that ceiling!

I have used them starlight kits before, and heres the instructions if anyone requires them

If you don't have a multimeter, you could consider putting a lamp across the live and neutral at the connection block prior to the trany. To see if it comes on.
Isolate circuit prior to disconnecting trany and connecting test lamp.

Gotta say that not been on the site for a while now and forgot how great people on here are...thanks for all the replies and help. Bought some new bulbs on e-bay to try first then will cut ceiling!

Looks like the ceiling has been dropped? I assume there is no loft above where you could form access?

The connection to the transformer should be done with a joint box, not terminal blocks. The transformer should be accessible.

You could leave the transformer floating, using a J501 joint box on the mains supply to it, and cut a single, double, or even a circular dry lining box into the ceiling with a blank plate on it.

Did you get an Electrical Installation Certificate and a Building Regulations Completion Notice for the work?
