AC
The alternator system provides electrical energy to charge the
battery and for operation of accessory circuits. A solid state
rectifier-regulator is mounted externally on the engine or on
the equipment powered by the engine. The system also includes
an alternator-stator and permanent magnet ring inside the fly-
wheel. With the exception of the magnet ring which revolves
around the stator, these systems have no moving parts and are
therefore virtually service free
- -
the only required service
is an occasional check to make sure that all electrical connec-
tions are tight and that wires are not frayed or cracked.
