Ford Superduty battery and charging issue

And how is rewinding an alternator much different than when I used to rewind the armatures of the electric motors of my early day slot cars as a kid, for lower resistance and ability to take more amps and create more torque? Just asking, I'd think the principles are related.

When a good friend of mine, doing elevator renovations needed a big motor rewound, the job always went to Little John's, I think over there by Paramount, CA and the Farmer John's pig farm /butcher shop.
