Notic e for Maintain Ge nerator
：
1.Do not mistake the polarit y of IG connection pole and L connection pole.
2.The line between IG connection pole and L connection pole should not be short circuit, do remember to pass through
the charging indicator lamp when connect them.
3. There should be no load between the IG coil and E pole.
2 ． Equipment position figure of charging circuit starting and

Battery
The ing charg ing circui t is shown as figure 8-1. The charging
system is a system charging the battery with the output electricity o f the AC
generator .
When the ignition switch is connected, curren t flows into the
excitation coil, and the coil is initially powere d. When the engine starts ,
stator coil begin to generate electricity , the exci tation coil is powered by the
output current of stator coil.
The output power of th e AC gen erator inc reases with the augment of
excitation current. And dec reases wi th the fall of the current. When the
battery voltage
（ the voltage of the S end of AC gene rator) reaches the
adjusting voltage, the exci ation current is cut off. And when the
start and
t battery
voltage is less than the adjusting volta ge , the v oltage adjustor controls the
excitation current to adjust the output voltage and keep it invariableness.
