3. CHARGING CIRCUIT
When the starter is activated and the engine is started, the operator release the start switch to the ON
position. Charging current generated by operating alternator flows into the battery.
The current also flows from alternator to each electrical component through the fusible link(CN-60)
and the fuse box.

CHECK POINT
GND : Ground
Cautions
1. When using an arc welder, always disconnect the ground lead from the battery to prevent alternator
or battery damage.
2. Attach the welding ground clamp as close to the weld area as possible to prevent welding current
from damaging the bearings of the alternator.
3. Do not disconnect the battery when the engine is running. The voltage surge can damage the
diode and resistors in the electrical system.
4. Do not disconnect an electric wire before the engine is stopped and the switchs are OFF.
