Charging System
General Description
Battery DescriptionS7RS0B1A01001
The battery has three major functions in the electrical
system.
• It is a source of electrical energy for cranking the engine.
• It acts as a voltage stabilizer for the electrical system.
• It can, for a limited time, provide energy when the electrical load exceeds the output of the generator.
Carrier and Hold-Down
The battery carrier should be in good condition so that it
will support the battery securely and keep it level. Before
installing the battery, the ba ttery carrier and hold-down
clamp should be clean and free from corrosion and
make certain there are no parts in carrier.
To prevent the battery from shaking in its carrier, the
hold-down bolts should be tight enough but not over-
tightened.
Electrolyte Freezing
The freezing point of electrolyte depends on its specific
gravity. Since freezing may ruin a battery, it should be
protected against freezing by keeping it in a fully
charged condition. If a battery is frozen accidentally, it
should not be charged until it is warmed.
Sulfation
If the battery is allowed to stand for a long period in
discharged condition, the lead sulfate becomes
converted into a hard, cryst alline substance, which will
not easily turn back to the active material again during
the subsequent recharging. “Sulfation” means the result
as well as the process of that reaction. Such a battery
can be revived by very slow charging and may be
restored to usable condition but its capacity is lower than
before. Built-In Indicator (If Equipped)
The battery has a built-in temperature compensated
indicator in the top of the battery. This indicator is to be
used with the following diagnostic procedure. When
checking the indicator, make sure that the battery has a
clean top. A light may be needed in some poorly-lit
areas.
Three types of indication available under normal
operation are as follows.
•
Green dot
Battery is sufficiently charged for testing.
• Dark
Battery must be charged before testing. If there is a
cranking complaint, battery should be tested as
described in “Battery Inspection”. Charging and
electrical systems should also be checked at this time.
• Clear
This means that fluid level is below the bottom of
hydrometer. Its possible cause is excessive or
prolonged charging, a broken case, excessive tipping
or normal battery deteriorat ion. When the battery is
found in such condition, it is possible that high
charging voltage is caused by the faulty charging
system and therefore, charging and electrical systems
need to be checked. If there is a trouble in cranking
and its cause lies in the battery, it should be replaced.

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.
• Do not connect any load between “L” and “E” terminals.
• When connecting charger or booster battery to vehicle battery, refer to “Jump Starting in Case of Emergency”.
