Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System
Description in Section 1A”.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.

Diagnostic Information and Procedures
Battery InspectionS7RS0B1A04001
Common Causes of Failure
A battery is not designed to last indefinitely; however, with proper care, it will provide many years of service. If the
battery performs satisfactorily during te st but fails to operate properly for no apparent reason, the following are some
factors that may point to the cause of trouble:
• Accessories left on overnight or for an extended period without the generator operating.
• Slow average driving speeds for short periods.
• Electrical load exceeding generator output partic ularly with addition of aftermarket equipment.
• Defects in charging system such as high resistance, s lipping drive belt, loose generator output terminal, faulty
generator or voltage regulator, Refer to “Generator Symptom Diagnosis”.
• Battery abuse, including failure to keep battery cable terminals clean and tight or loose battery hold down.
• Mechanical problems in electrical sys tem such as shorted or pinched wires.
Visual Inspection
Check for obvious damage, such as cracked or broken case or cover, that could permit loss of electrolyte. If obvious
damage is noted, replace battery. Determine cause of damage and correct as needed.
Generator Symptom DiagnosisS7RS0B1A04002
CAUTION!
• Do not mistake polarities of “IG” terminal and “L” terminal.
• Do not create short circuit between “IG” and “L” terminals. Always connect these terminals through a lamp.

Generator Test (Undercharged Battery Check)S7RS0B1A04003
This condition, as evidenced by slow cranking or
indicator clear with dark or light yellow dot can be
caused by one or more of the following conditions even
though indicator lamp may be operating normal.
The following procedure also applies to cars with
voltmeter and ammeter.1) Make sure that undercharged condition has not been caused by accessories left on for extended period of
time.
2) Check drive belt for proper tension.
3) If battery defect is suspected, refer to “Battery Description”.
4) Inspect wiring for defects. Check all connections for tightness and cleanliness, battery cable connections
at battery, starting motor, ignition ground cable and

Lower than recommended pressure can cause:
• Tire squeal on turns
• Hard Steering
• Rapid and uneven wear on the edges of the tread
• Tire rim bruises and rupture
• Tire cord breakage
• High tire temperature
• Reduced handling
• High fuel consumption
Replacement Tires
When replacement is necessary, the original equipment
type tire should be used. Refer to the Tire Placard.
Replacement tires should be of the same size, load
range and construction as those originally on the vehicle.
Use of any other size or type tire may affect ride,
handling, speedometer / odometer calibration, vehicle
ground clearance and tire or snow chain clearance to the
body and chassis.
It is recommended that new tires be installed in pairs on
the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to
equalize braking traction.
WARNING!
Do not mix different types of tires on the
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because
handling may be seriously affected and may
result in loss of control.

The metric term for tire infl ation pressure is the kilo
pascal (kPa). Tire pressures is usually printed in both
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS7RS0B2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, air leak through welds,
have elongated bolt holes, if lug wheel bolts won’t stay
tight, or if they are heavily rusted. Wheels with greater
runout than shown in the following may cause
objectional vibrations.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer / odometer calibration, vehicle
ground clearance and tire clearance to body and
chassis.
How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an
accurate dial indicator. The tire may be on or off the
wheel. The wheel should be installed to the wheel
balancer of the like for proper measurement.
Take measurements of both lateral runout “a” and radial
runout “b” at both inside an d outside of the rim flange.
With the dial indicator set in place securely, turn the
wheel one full revolution slowly and record every reading
of the indicator.
When the measured runout exceeds the specification
and correction by the balancer adjustment is impossible,
replace the wheel. If the reading is affected by welding,
paint or scratch, it should be ignored.
Lateral runout limit “a”
: 0.3 mm (0.012 in.)
Radial runout limit “b”
: 0.3 mm (0.012 in.)

Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If broken stud or nut are found, be sure to replace both
stud and nut with new one.
Irregular and/or Premature Wear DescriptionS7RS0B2401003
Irregular and premature wear has many causes. Some
of them are as follows: incorrect inflation pressures, lack
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with “feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will app ear as 12 mm (0.47 in) wide
bands when the tire tread depth becomes 1.6 mm (0.063
in).
When the indicators (1) appear in 3 or more grooves at 6
locations, tire replacement is recommended.

If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
