After discussing this at length with some other mech engineers we reckon that there should be enough residual field left in the crank to start the alternator up.. .. .After managing to restrain ourselves from going out to the apron and bastardising a cessna 150. We have decided that the only way to satisfy ourselves is to get a old alternator rigged up on a bench. So once we managed to get a decent 110v hilty power drill i will let you know what happens.. .. .MJ
