BATTERY PFP:00011
How to Handle Battery EKS00313
CAUTION:

If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.

After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.

Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.

The battery surface (particularly its top) should always be kept
clean and dry.

The terminal connections should be clean and tight.

At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.

When the vehicle is not going to be used over a long period of
time, disconnect battery cable at negative terminal. (If the vehi-
cle has an extended storage switch, turn it off.)

Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Fig. 4 INITIAL CHARGING CURRENT SETTING (Standard charge)

Check battery type and determine the specified current using the table shown above.

After starting charging, adjustment of charging current is not necessary.
Fig. 5 ADDITIONAL CHARGE (Standard charge)
CAUTION:

Do not use standard charge method on a battery whose specific gravity is less than 1.100.

Set charging current to specified value in Fig. 4. If charger is not capable of producing specified
current value, set its charging current as close to that value as possible.

Keep battery away from open flame while it is being charged.

When connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.

If battery temperature rises above 55 °C (131 °F), stop charging. Always charge battery when its
temperature is below 55 °C (131 °F).

C: QUICK CHARGE
Fig. 6 INITIAL CHARGING CURRENT SETTING AND CHARGING TIME (Quick charge)

Check battery type and determine the specified current using the table shown above.

After starting charging, adjustment of charging current is not necessary.
CAUTION:

Do not use quick charge method on a battery whose specific gravity is less than 1.100.

Set initial charging current to specified value in Fig. 6. If charger is not capable of producing spec-
ified current value, set its charging current as close to that value as possible.

Keep battery away from open flame while it is being charged.

When connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.

Be careful of a rise in battery temperature because a large current flow is required during quick-
charge operation.
If battery temperature rises above 55 °C (131 °F), stop charging. Always charge battery when its
temperature is below 55 °C (131 °F).

Do not exceed the charging time specified in Fig. 6, because charging battery over the charging
time can cause deterioration of the battery.

CHARGING SYSTEM

CHARGING SYSTEM PFP:00011
System Description EKS00316
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times

through 10A fuse (No. 34, located in the fuse and fusible link box)

to alternator terminal 4 (S).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 (S) detecting the input voltage. The charging circuit is protected by
the 120A (Gasoline engine models) or 100A (Diesel engine models) fusible link (letter A, located in the fuse
and fusible link box).
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 11, located in the fuse block (J/B)]

to combination meter terminal 2 for the charge warning lamp.
Ground is supplied with power and ground supplied

to terminal 5 of the combination meter

through alternator terminal 3 (L)

to alternator terminal E (Gasoline engine models) or through body ground (Diesel engine models)

through body ground E30 (Gasoline engine models).
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

Trouble DiagnosesEKS00319
Before performing an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Table.

Before starting, inspect the fusible link.

Use fully charged battery.
WITH IC REGULATOR
NOTE:

If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque and voltage drop.)

Check condition of rotor coil, rotor slip ring, brush and stator coil. If necessary, replace faulty parts with
new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate “CHARGE” warning lamp, if any of the following
symptoms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.
