3) Specific gravity of electrolyte
Measure specific gravity of electrolyte using a hydrometer
and a thermometer.
Specific gravity varies with temperature of electrolyte so
that it must be corrected at 20°C (68°F) using the follow-
ing equation:
S
20= St + 0.0007 x (t 20)
S
20:Specific gravity corrected at electrolyte tempera-
ture of 20°C (68°F)
St :Measured specific gravity
t :Measured temperature °C
Determine whether or not battery must be charged,
according to corrected specific gravity.
Standard specific gravity: 1.220 — 1.290 [at 20°C
(68°F)]
Measuring the specific gravity of the electrolyte in the bat-
tery 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.
C: CHARGING
WARNING:

Do not bring an open flame close to the battery at
this time.
CAUTION:

Prior to charging, corroded terminals should be
cleaned with a brush and common baking soda solu-
tion.

Be careful since battery electrolyte overflows while
charging the battery.

Observe instructions when handling battery
charger.

Before charging the battery on vehicle, disconnect
battery ground terminal. Failure to follow this rule may
damage generator’s diodes or other electrical units.
1. NORMAL CHARGING
Charge the battery at current value specified by manufac-
turer or at approximately 1/10 of battery’s ampere hour
rating.
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.
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.

CAUTION:

Observe the items in 1. NORMAL CHARGING
[W2C1].

Never use more than 10 amperes when charging the
battery because that will shorten battery life.

CAUTION:
Before checking the headlight aiming, be sure of the
following:

Turn off the light before adjusting headlight aiming.
If the light is necessary to check aiming, do not turn on
for more than two minutes.

The area around the headlight has not sustained any
accident, damage or other type of deformation.

Vehicle is parked on level ground.

The inflation pressure of tires is correct.

Vehicle’s gas tank is fully charged.

Bounce the vehicle several times to normalize the
suspension.

Make certain that someone is seated in the driver’s
seat.
NOTE:
Adjust vertical aim first, then horizontal aim.
