It must not be so simple/cheap to regulate current, or they would
probably do it. They do put in that dirt cheap fusable link.

Just takes money AKA: Larger conductors, AKA: More copper.

Using system voltage to control field current (usually no more than 5Amps),
thus controlling alternator output, is very straight forward.

If a bad battery, or a defective cable, wipes out an alternator, that's not
the alternator's fault, that's a system problem, IMHO.
