CAUTION:
If it becomes necessary to start the engine with a booster
battery 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
specific gravity.
How to Handle Battery
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-dis-
charging a battery.
lThe battery surface (particularly its top) should always be
kept clean and dry.
lThe terminal connections should be clean and tight.
lAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ``low mainte-
nance'' and ``maintenance-free''.
lWhen the vehicle is not going to be used over a long period
of time, disconnect the negative battery terminal.
lCheck 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 touching a battery, do not
touch or rub your eyes until you have thoroughly washed
your hands. If acid contacts eyes, skin or clothing, immedi-
ately flush with water for 15 minutes and seek medical atten-
tion.

Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and
suitable test probes are necessary for the test. The alternator can be checked easily by referring to the
Inspection Table.
lBefore starting, inspect the fusible link.
lUse fully charged battery.

lWhen field 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:
lField circuit is open.
lExcessive voltage is produced.
