CHARGING
Measuring the specific gravity of the electrolyte in the battery
will disclose the state of charge of the battery. The relation
between the specific gravity and the state of charge is as shown
in figure.

a. Do not bring an open flame close to the battery at this
time.
b. Prior to charging, corroded terminals should be cleaned
with a brush and common baking soda solution.

Battery
A9-005
The battery must be charged when indicator shows "charging
necessary" and also engine does not start.
Perform charging for 5 hours or more with a constant current
of6A.
At the condition of full charged, the charging current is O.5A
or less.
2) Quick charging
Quick charging is a method in which the battery is charged in
a short period of time with a relatively large current by using
a quick charger.
13
Since a large current flow raises electrolyte temperature, the
battery is subject to damage if the large current is used for
prolonged time. For this reason, the quick charging must be
carried out within a current range that will not increase the
electrolyte temperature above 40°C (104°F).
It should be also remembered that the quick charging is a
temporary means to bring battery voltage up to a fair value
and, as a rule, a battery should be charged slowly with a low
current.
a. Observe the items in NOTE in 1) Normal charging.
b. The battery should not be charged with 1DA or more.
Fuse
FUSE BOX
The fuse box is located underneath of the instrument panel:
The connection between each fuse and main electrical
units/devices is as shown in the following illustration. (Also
refer to the wiring diagram at the end of this manual.)

a. When replacing fuse, be sure to use fuse of specified rating.
b. If fuse is blown, be sure to eliminate cause before installing
new fuse in position.
c. Poor contact of any fuse holder will often lead to voltage
drop or heating in the circuit or fuse holder and could result
in blown fuse, so be careful with holder contacting and clean
metal parts if necessary.
