DESCRIPTION
The conventional internal voltage detection type
alternator controls the charging voltage regardless of the
battery condition and according to the external load
change so that it sometimes causes battery under or
over charging or causes flickering of meters and lamps
due to ripples of generated voltage resulting from load
fluctuation. The figure below show the internal circuits of
the alternator and voltage regulator.
