Specific gravity reading at 20 °C

Condition Adjustment procedure
(68 °F )
1.280 to 1.260 or more Good If the difference in S.G. between any two
cells is 0.04 or less, continue to use as is.
If the difference is more than 0.04 ,
discharge the battery in an efficient
manner. If the battery recovers, charge
the battery to adjust the electrolyte S.G.
1.260 or lower to 1.220 or more Half charged Recharge battery to adjust electrolyte
S.G.
Check for any short-circuited cables or
corroded cable connections in the
electrical system.
1.220 or lower Battery low (caution required) Recharge battery.
If the difference in S.G. is too much,
charge the battery to adjust the

If the difference in S.G. between cells is A cell with a low S.G. may have a short Charge the battery until the voltage and

too high or too low. If the difference in S.G. is more than
0.040 and a low S.G. is found in any of
the cells, replace the battery with a new
one. Conduct a high current discharge
test after leaving the battery for 12 to 96
hours.
6.2 Electrolyte Specific Gravity and State of Charge

The fully charged condition can be checked with the

electrolyte S.G. (1.280 to 1.260), and also the electrolyte
decreasing rate shows a charging condition. If the
electrolyte in the battery cell decreases to the level where
the pole plates are exposed within one month, the battery
may be overcharged. If the electrolyte amount remains
sufficient for more than three months, the battery may be
poorly charged.
6.3 Precautions for Charging Battery

(1) In a slow charging, the charging current should be

about 1/10 of the capacity of battery.
(2) In quick charging, the battery capacity in ampere (A)
should not be exceeded.
(3) During charging, adjust the charging current so that
the electrolyte temperature does not exceed 45 °C (113
°F).
(4) When connecting cables to battery terminals, always
connect the positive (+) terminal first, and when
disconnecting, remove the negative (-) terminal first.

R CAUTION
Be sure to turn off the key switch and light switch before disconnecting or connecting the battery cables.
(This prevents damage to the IC regulator.)

CHAPTER 3 ELECTRICAL SYSTEM
6.4 Precautions to Handle Alternator Charging System

The alternator is integrated with an IC voltage regulator.

Pay attention to the followings to maintain and check the
electrical system.
- Do not connect battery cables in reverse polarity.
- Do not disconnect any battery cable while the engine is
running.
L
- Do not ground the terminal L.
- Do not make a short circuit between the terminal L and R
R.
- Do not apply a blast of steam cleaner directly to the B
alternator, or the IC regulator may be damaged. 500052
