CAUTION:
If it becomes necessary to start the engine with a booster bat-
tery and jumper cables,
a. Use a 12-volt booster battery.
b. After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
c. Never add distilled water through the hole used to check
speci®c gravity.
How to Handle Battery
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharg-
ing 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 speci®c gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery ¯uid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
¯ush with water for 15 minutes and seek medical attention.

Trouble Diagnoses
Before conducting 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 Inspec-
tion Table.
+Before starting, inspect the fusible link.
+Use fully charged battery.

Note:
+If the inspection result is OK even though the charging system is malfunctioning, check the B ter-
minal connection. (Check the tightening torque.)
+When ®eld circuit is open, check condition of rotor coil, rotor slip ring and brush. 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.
