Fixed the smoke problem and just tried the drill idea, I was right to be
sceptical :-(
Also tried flashing with a 30V/2A power supply but it didn't do any good
- probably not enough current.

Whoops !
Flashing is normally only necessary on brush type alternators and even then
only a 9v-pp3 battery is enough on small domestic types.
Self energising brushless alternators have varied methods of energising the
exciter field windings, a supply is sometimes taken from the driving motors
flywheel gen, or a capacitor is used with a separate pickup coil.
As I said fault-finding without the wiring diagram or understanding how that
particular generator works is not easy.
Of all the DOA small generators I have bought with Zero output, the problem
has been corroded connections causing high resistance in the exciter
circuit.
