I've solved the mystery by a) getting my multi-meter out of the garage and b) blowing the dust off the sticker inside the old fan.
Turns out that I bought an SELV fan all those years ago, and there is a transformer in the ceiling void that steps the voltage down to 12v.
Fucksticks. I'm going to make removing the transformer the electricians problem I think, unless anyone knows of a cunning method of resolving this?
Was going to say, do the fans both need the same voltage. But that's been cleared up apparently. Can you not get a new 12v fan instead of tearing the wiring out to suit the fan you've got now? Must be less expensive?
