Description of Charging SystemAll Models The outboard charging system consists of battery, flywheel, an alternator stator
metal laminationsThe stator is attached to the ignition plate (4 amp models) or mounting plate (12 amp models)The flywheel's
magnetic lines of force cutting through the stator windings produce alternating currentThe stator or its leads could be damaged
which could result in reduced or no alternator outputThe rectifier consists of series of diodes, built into metal case, which
changes the stator's alternating current to the direct current used to charge the batteryOne, several, or all of the rectifier
diodes might become damaged, resulting in system grounded condition, no charge condition, or an incorrect charging rateThe
