almost every alternator seemed to have no magnets in the rotor to generate power. in there are coils. the current for the coils is come fromr the alternator himself.
once, many years ago, i had a voltage gauge and a bad alternator. i guess, one of three diodes for the exiting current was unsoldered. i think so, because some weeks later one diode does a gigant shortcut directly in the alternator.
however, with only 2 diodes the voltage drops down, slightly over the batterie voltage. a little charge remained, as long as no power was needed.
i afraid, in nower days it might be impossibel, to reach and modify the inner parts of a regulator.
but the honda story is verry intersting. i´d like to see some wiring and a list of cars, using this. it´s been arround since 20 years, and european car makers now feeding their comercials with this stuff.
