CHARGING SYSTEM 7.7
GENERAL
The charging system consists of the alternator and regulator.
Charging system circuits are shown in Figure 7-27.
NOTE
Never install accessory wiring between battery post and bat-
tery cable. Installing wire between battery post and battery
cable could cause damage to electrical system.
When installing electrical accessories, install longer battery
post fasteners. Install wiring between battery cable and fas-
tener.
Alternator
The alternator consists of two main components:
●
The rotor which mounts to the engine sprocket shaft.
●
The stator which bolts to the engine crankcase.
Voltage Regulator
See Figure 7-25. The voltage regulator is a series regulator
with shunt control. The voltage regulator combines the func-
tions of rectifying (converting AC voltage to DC) and regulat-
ing (controlling voltage output).
TROUBLESHOOTING
When the charging system fails to charge or does not charge
at a satisfactory rate, check the following:
Battery
Check for a weak or dead battery. See 7.11 BATTERY. Bat-
tery 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 7-27.
Voltage Regulator Inspection
See Figure 7-26. The plug connector to stator must be clean
and tight.
