CHARGING SYSTEM
GENERAL
5682
Voltage regulator
The charging system consists of the alternator and regulator.
See
page 7-25
for charging system circuits.
Alternator
The alternator consists of two main components: the rotor
which is mounted on the engine sprocket shaft, and the sta-
tor, which is bolted to the engine crankcase.
Voltage Regulator
See
Figure 7-18.
The voltage regulator is a series regulator
with shunt control. The circuit combines the functions of recti-
fying and regulating.

TROUBLESHOOTING
When the charging system fails or does not charge at a satis-
factory rate, it is recommended that the following checks be
made.
Battery
Check for a weak or dead battery. See
BATTERY
in
Section 1. Battery must be fully charged in order to perform
any electrical tests.
Wiring
Check for corroded or loose connections in the charging cir-
cuit. See
Figure 7-19.
Voltage Regulator Inspection
The voltage regulator base must have a clean, tight connec-
tion for proper grounding. Check by using an ohmmeter with
one lead on a known good ground, such as battery ground
cable, and the other on the regulator base.
Connector plug to engine crankcase must be clean and tight.
