How to Handle Battery INFOID:0000000004306818
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 the negative battery terminal.
• Check the charge condition of the battery. Periodically check the specific gr avity 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 yo u have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, imme diately flush with water for 15 minutes and seek medical attention. MEL041F

CHARGING THE BATTERY
CAUTION:
• Do not “quick charge” a fully discharged battery.
• Keep the battery away from open flame while it is being charged.
• When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the
charger first, as this may cause a spark.
• If battery electrolyte temperature rises above 55 °C (131 °F), stop charging. Alw ays charge battery at a
temperature below 55 °C (131 °F).
Charging Rates
Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automat ically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing norma lly as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
• If, after charging, the specific gravity of any two ce lls varies more than 0.050, the battery should be replaced.
Trouble Diagnosis with Battery Service Center INFOID:0000000004306819
For battery testing, use Battery Serv ice Center (J-48087). For details and operating instructions, refer to Tech-
nical Service Bulletin and/or Battery Service Center User Guide.
Removal and Installation INFOID:0000000004306820
REMOVAL 1. Disconnect battery negative (1) and positive (2) terminals. CAUTION:
When disconnecting, disconnect the battery negative termi-
nal first.
2. Remove battery hold-down wedge bolt (A) and remove battery hold-down wedge bracket (3).
3. Remove battery cover.
4. Remove battery. −

CHARGING SYSTEM
System Description INFOID:0000000004306825
The generator provides DC voltage to operate the vehicl e's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to generator terminal 3 through
• 10A fuse (No. 29, located in the fuse and fusible link box).
Power is supplied through terminal 1 to charge the batte ry and operate the vehicle's electrical system. Output
voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120A fusible link
[letter a , located in the fusible link box (battery)].
Ground is supplied
• to generator terminal 5
• through body ground F5, and
• through the generator case to the cylinder block
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 3, located in the fuse block (J/B)]
• to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the generator.
When the ignition is turned on and power becomes availabl e at terminal 2, this "wakes up" the regulator. The
regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With
power and ground supplied, the charge warning lamp will il luminate. When the generator is providing sufficient
voltage, 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.

WORK FLOW
DIAGNOSTIC PROCEDURE 1
Check Charge Warning Lamp Circuit OK >> GO TO 2.
NG >> Repair terminal 2 connection. Confirm repair by performing complete Starting/Charging system test. Refer to diagnostic station instruction manual. B

OK >> GO TO "WORK FLOW" .
NG >> Check the following.
• 10A fuse [No. 3, located in fuse block (J/B)]
• CHARGE lamp
• Harness for open or short between combination meter and fuse
• Harness for open or short between combination meter and generator
DIAGNOSTIC PROCEDURE 2
Check Battery Circuit OK >> GO TO 2.
NG >> Repair terminal 1 connection. Confirm repair by performing complete Starting/Charging system
test. Refer to diagnostic station instruction manual. OK >> GO TO 3.
NG >> Check the following. • 120A fusible link [letter a , located in fusible link box
(battery)]
• Harness for open or short between generator and fus- ible link OK >> Replace the generator. Refer to
SC-25, " Removal and
Installation " . Confirm repair by performing complete
Starting/Charging system test. Refer to diagnostic sta-
tion instruction manual.
NG >> Check harness between the battery and the generator for poor continuity.
DIAGNOSTIC PROCEDURE 3
