BATTERY
CHARGING RATE AND SPECIFIC GRAVITY
OF BATTERY ELECTROLYTE
The relationship between the charged condition
of the battery and the specific gravity of battery
electrolyte differs,
as shown in figures below,
when the battery
is discharging and when it IS
being charged
Charging battery at a curreni 1/10 battery capacity
100 80 60 40 20 0
Charged rare (I" %J SEL8088
Chargtng battery at a curreni 116 of battery capacity
100 80 60 40 20 0
Charged rate (In %) SEL809B
As can be seen from these figures, the battery has
the following features
The specific gravity of battery electrolyte
increases very slowly while the battery is being
charged
The smaller the charging current, the slower
the specific gravity of the electrolyte increases
ling
WARNING:
a. Keep battery away from open flame while
it is being charged
b When connecting charger, connect leads
first, then
turn on charger. Do not turn on
charger first, as this may cause a spark.
c. Do not allow electrolyte temperature to go
over45"C (113°F).
CHARGING CURRENT AND TIME
REQUIRED
FOR CHARGING
Charge the battery at 1/10 the current of battery
capacity
Charging current I Time required
1/10 of battery capacity I Approx 8 - 10 hours
116 of battery capacity
(But not more than 10-ampere) Approx 4 - 5 hours ~~
~
CAUTION:
Do
not use more than 10-ampere current flow to
charge the battery quickly, as
this will shorten the
battery's service life.

METER OUTPUT CHECK
Combination meter emits speed sensor signal to
control

unit, voice warning
unit and AIT control unit.
Disconnect speedometer cable from speed sen-
sor and remove speed sensor with harness con-
nected 1
2 Remove cluster lid A.
3 Disconnect combination meter harness from
instrument harness
as shown, and connect an
ohmmeter between @ and 0

Turn ignition switch "OFF" + "ON".
Slowly turn speed sensor rotor shaft with a
suitable screwdriver to make sure ohmmeter
pointer deflects.
Ohmmeter pointer deflects twice for each rotatton
of rotor shaft

If ohmmeter pointer does not deflect, go to
"Speed Sensor Output Check". (Refer to back
