Low voltage downlighters issue

[DeeGee]

Hi

I have 9 low voltage down lighters in my kitchen. 4 are run off one transformer, and 5 off another. Recently the 5 have stopped working but the 4 still work. Both transformers are run from the same junction box and controlled by the same switch. I have checked that the bulbs themselves have not blown, but am now out of ideas.

It's a bungalow so the wiring & tranformers are very accessible in the loft space. Any help would be much appreciated

Thanks

I suppose it couldn't be that the transformer has blown? They often have a built-in over temperature fuse embedded in the winding.
