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.

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

Never 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. Never 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).

Never exceed the charging time specified in Fig. 6, because charging battery over the charging
time can cause deterioration of the battery.

Removal and Installation EKS00315
Observe the following to ensure proper servicing.
CAUTION:

When disconnecting, disconnect the battery cable from the
negative terminal first. But when connecting, connect the
battery cable to the positive terminal first.

Tighten parts to the specified torque shown below.
Battery fix frame mounting nut:
: 3.5 - 5.3 N·m (0.36 - 0.54 kg-m, 31 - 46 in-lb)
Battery cable tightening nut:

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” terminal 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” terminal) 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” terminal)

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

through 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 DiagnosisEKS00319
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
Ta b l e .

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 malfunctioning
parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

1. Remove through-bolt (4).
2. Remove rear cover.
NOTE:
Rear cover may be hard to remove because a ring is used to
lock outer race of rear bearing. To facilitate removal of rear
cover, heat just bearing box section with a 200 W soldering iron
until the temperature increases by about 30 °C.
