CHECKING THE ELECTRICAL
COMPONENTS
CHECKING AND CHARGING THE SUB-
BATTERY
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of
poisonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
Wear protective eye gear when handling or
working near batteries.
Charge batteries in a well-ventilated area.
Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
DO NOT SMOKE when charging or han-
dling batteries.
KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
Skin — Wash with water.
Eyes — Flush with water for 15 minutes
and get immediate medical attention.
INTERNAL
Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg
or vegetable oil. Get immediate medical at-
tention.
This is a sealed battery. Never remove the
sealing caps because the balance between
cells will not be maintained and battery
performance will deteriorate.
Charging time, charging amperage and
charging voltage for an VRLA (Valve Reg-
ulated Lead Acid) battery are different
from those of conventional batteries. The
VRLA (Valve Regulated Lead Acid) battery
should be charged as explained in the
charging method illustrations. If the bat-
tery is overcharged, the electrolyte level
will drop considerably. Therefore, take
special care when charging the battery.
Since VRLA (Valve Regulated Lead Acid) bat-
teries are sealed, it is not possible to check the
charge state of the battery by measuring the
specific gravity of the electrolyte. Therefore, the
charge of the battery has to be checked by
measuring the voltage at the battery terminals.
1. Remove:
Seat
2. Disconnect:
Sub-battery leads
(from the sub-battery terminals)
First, disconnect the battery negative lead
"1", and then battery positive lead "2".
3. Remove:
Battery band
Sub-battery
4. Measure:
Battery charge
a. Connect a pocket tester to the battery termi-
nals.
Tester positive probe → battery positive
terminal
Tester negative probe → battery negative
terminal
The charge state of an VRLA (Valve Regulat-
ed Lead Acid) battery can be checked by
measuring its open-circuit voltage (i.e., the
voltage when the positive battery terminal is
disconnected).
No charging is necessary when the open-cir-
cuit voltage equals or exceeds 12.4 V.
b. Check the charge of the battery, as shown in
the charts and the following example.
