Anyone care to guess why this was?
If it's not an oxidized contact somewhere (plug pins or fuse clips, or even a faulty plug fuse (the end caps are pressed on and in some designs of fuse, make contact with another disc connected to the fuse element), then I would suggest that the coil has a tiny break in it somewhere, and the mains can break down the carbonised gap but the low voltage from the meter can't.
