The same voltage regulator runs all the different amp alternators. So the field current is no different, The internal windings of the alternator are.

The cars With few electrical accessories get the lower amp alternators the AC and power everything cars get the big amp unit’s.

That is not true. Back in the grounded field days, there was a factory heavy duty regulator. It was nearly square.
