3. CHARGING CIRCUIT
When the starter is activated and the engine is started, the operator releases the starting switch to
the ON position.
Charging current generated by operating the alternator flows into the battery through the battery
relay [CR-1].
The current also flows from the alternator to each electrical component and controller through the fuse
box.
