Digital voltmeters detect all sorts of stray voltages. Seven dynamos do seem prone to lose magnetisation. Re polarisation is often helpful.
It is a long shot but if the field is connected backwards the dynamo generates an output which cancels the field so it will never get going.
It is very unlikely the armature is wound wrong . Even if given a bare armature and the wrong one as a pattern I think the comm section numbers is different, and one has armature poles in a slight helix form..
