Re: [T3] alternator

You can reverse the direction of a generator by "repolarizing" the fields. A
generator must have some residual magnetism in the fields, to get it started.
If you reverse the polarity, as it is shown in the Bentley, it will now charge
backwards.
I have run into this when having a generator rebuilt, and the shop's test stand
is rotating reverse of what a VW rotates.
