Failing 12v downlighters - any ideas?

bulb. bulb socket, cable or transformer. A multimeter will tell you which,

Transformers do not have an infinite life span so they may well need replacing once in a while.

You should be able to pull the transformer through the hole in the ceiling once you have pulled out the light fitting.

Providing it was left enough spare wire of course. :¬)

Burnt out lamp connectors is the usual cause

I had this problem. On investigation, something had eaten the low voltage wires close to the fitting - I suspect squirrels.

I couldn't pull the transformers out cos does not seem to be enough spare wire - surely I don't have to take the ceiling down to get to the transformers - ugh !!!! Unless that is, the transformers are black plastic boxes about 1cm x 2cm and attached to the light fitting? I assumed these black boxes were just mini

Can you get to the other end of the wire? If so it may be possible to use it to pull a string and then a longer length through.

cheers, Pete.

You may find there is one transformer supplying several lights, so you may need to pull several fittings out before you find it :-0)

If this is the case, then the transformer is not the problem (assuming the other lights on it are OK!) Firstly I would open the little junction box on the light fitting and test if there is power there, setting the meter to AC volts. (If you don't have a meter, and it is defiantly 12v, then you can just try to connect the legs of a bulb to the wires - But don't short them together, as this may kill the transformer!)
