Hi there. I have read a few posts about halogen lights not working, but still can't solve the problem. All six halogen lights in my bathroom failed at the same time. I have changed bulbs to no avail. I have tested a bulb on the wire from the 12v output and it works, so the transformer (which powers all 6 lights) seems to work. I can't now work out, why if there is 12v power on the wire to the ceramic light fitting, the lights don't work, and what would have caused them all to stop working at the same time. Any suggestions? Thanks
 
Hmmm, if the lamp lights when you connect it directly to the output of the transformer then it sounds like a loose wire or bad connection. The wiring on the secondary side of lighting transformers is particularly prone to failure because of the very high currents involved. It's also possible that the transformer has an integrated secondary fuse that's blown and when you did your test you somehow inadvertently bypassed the blown fuse. Post a few pictures of the transformer and the connections, it might help us give you better info.
 
Get your test meter out and test it.
 
Thanks for the advice. I saw my sparky in the village, he suggested that, over time, I had changed bulbs and used 50w ones, so eventually the transformer has been overloaded. So I replaced all bulbs with 20w, no change, I then remove all but one bulb to see if just one would work, nothing....I don't have a tester, but I still don't understand how, if a bulb lights at a junction point, it doesn't light in the socket which is 2ft further down from the junction, unless, as has been suggested, the wire is faulty. Is it possible that all wires could fail at the same time due to me overloading the transformer? I would take a photo of the transformer, but my iPhone keeps saying memory full, which exasperates me and thousands of other users...and the transformer is a pig to get to...
 
Two things here....electronic transformers do not operate unless under load, so under load you need to check voltage....fault is either transformer gone, or fault on outgoing supply to halogens.
 
Where in northants are you?. This is my area so i could help if need be
 
Thanks - I'm in Eydon, Nr Daventry...and thanks Tazz. Maybe I'm being really thick, but if a light works, at a junction on the 12v side of the transformer, then presumably the transformer is working? And logic suggests that, if the light doesn't work when attached to a wire leading from that junction, then the wire is faulty. But if all that is true, what would cause all 5 lights to stop working at the same moment? Hence my question, could overloading have fried all wires at the same time?
