I find it a natural to rev the engine up upon starting it.It allows the engine to "clean itself out" and also indicates if the choke can be pushed in some.If you tried to rev and the engine sputters,you can fine tune the choke.Doing this once sets the 1-wire to ON and it charges no matter what speed then.I believe a generator has to turn 1200-1400 rpm before it charges at all,whereas an alternator will charge at speeds as low as 500-600rpm.When Chrysler jumped the market in 1960 and installed alternators on Valiants,they set up a bunch of them as taxi cabs and let them idle all day with lights and accessories on to show the value of the new Chrysler-Engineered Alternator.However all the cars sputtered to a stop,and would not re-start.Everybody thought the alternators were to blame and that tainted its reputation.When in fact the batteries were not dead,but the spark plugs all fouled out.Seems the oil control rings were poorly designed and idle speeds loaded the plugs with oil.A redesign of the rings solved the oil pumping problem,and Chrysler installed alternators on all 1961 cars.GM and Ford (and AMC,and imports) would take years to adopt the modern alternator.
A generator generates (very little) power from nothing,
An alternator takes low power and creates higher power....much more efficient.
