Cooker hood light mystery

[luxliners]

Just taken over a property and found a Stoves cooker hood installed. The cooker hood powers on and the fan works perfectly but the lights don't function. I ordered 2 new replacement holders and they fitted in perfectly with 2 new bulbs. Wired the new lights directly into the hood as per image and still no lights.

I have checked with a voltage tester and there is power going to the cables feeding both lights when I press the switch. Unsure what to check next any ideas wiring wise or get a new hood?

It looks like you've got one light wired into the neutral and the other wired into the live.....I think.

Thanks for that I noticed that as well I just copied how the original lights were wired up. This was how it was when I opened the cover and it never looks like it was tampered with although could be wrong. Lights are at the link below.

It probably never worked, you need to swap two of the white wires over.

When you tested it was 12v at the connector block I take it?

But they didn't work.

Thanks for the reply. I used one of those electrical tester pens and it went crazy beeping as soon as I touched the connector block and wires going to the lamp.

Not sure if it was 12V as didn't have a multimeter with me at the time. I will look at the wiring when I am at home later it might be the previous owner messed with the neutral and live connectors.

They don't like it up them Mr Mainwairing!

Not sure what the waveform might be as there will be a mains > 12v power supply somewhere. It could be that is the faulty item.
The older ones were made for halogen bulbs, so not sure if you'll get DC, AC or some chopped up voltage - if you are trying with your multimeter.

Try putting the wires back as they should be first though.

PS

I ordered 2 new replacement holders and they fitted in perfectly with 2 new bulbs.

Stoves have got a nerve charging £45.98 a pop for those replacement lamp holders. If its just the lamps then they are less than £1 each!
