COMPONENTS
Information in this section may only apply if any of
the following kits have been installed:
•
Electric Start Kit, P/N 586398

The charging system consists of a battery, fly-
wheel, alternator stator, and rectifier.

Flywheel

The engine's flywheel contains permanently
charged magnets. The magnets supply energy to
power the stator windings. The magnets must be
at their original design strength for full alternator
output.

Stator

The alternator stator has windings wrapped
around metal laminations. The flywheel's mag-
netic lines of force cutting through the stator wind-
ings produce alternating current.
9.9/15 Model (Accessory Alternator)

Rectifier

The rectifier consists of a series of diodes which
change the stator's alternating current to the direct
current used to charge the battery.
