TIP
Set the charging voltage to 16–17 V. If the set-
ting is lower, charging will be insufficient. If too
high, the battery will be over-charged.
c. Make sure that the current is higher than
the standard charging current written on
the battery.
TIP
If the current is lower than the standard charging
current written on the battery, set the charging
voltage adjust dial at 20–24 V and monitor the
amperage for 3–5 minutes to check the battery.
d. Adjust the voltage so that the current is at
the standard charging level.
e. Set the time according to the charging
time suitable for the open-circuit voltage.
f. If charging requires more than 5 hours, it is
advisable to check the charging current af-
ter a lapse of 5 hours. If there is any
change in the amperage, readjust the volt-
age to obtain the standard charging cur-
rent.
g. Measure the battery open-circuit voltage
after leaving the battery unused for more
than 30 minutes.
Charging method using a constant volt-
age charger
a. Measure the open-circuit voltage prior to
charging.
TIP
Voltage should be measured 30 minutes after
the engine is stopped.
b. Connect a charger and ammeter to the
battery and start charging.
c. Make sure that the current is higher than
the standard charging current written on
the battery.
TIP
If the current is lower than the standard charging
current written on the battery, this type of battery
charger cannot charge the VRLA (Valve Regu-
lated Lead Acid) battery. A variable voltage
charger is recommended.
d. Charge the battery until the battery’s
charging voltage is 15 V.
TIP
Set the charging time at 20 hours (maximum).
e. Measure the battery open-circuit voltage
after leaving the battery unused for more
than 30 minutes.
6. Install:

then the negative battery lead.
8. Check:
•
Battery terminal
Dirt
Clean with a wire brush.
Loose connection
Connect properly.

CHECKING THE RELAYS
Check each switch for continuity with the digital
circuit tester. If the continuity reading is incor-
rect, replace the relay.
1. Disconnect the relay from the wire harness.
2. Connect the digital circuit tester (
) and bat-
tery (12 V) to the relay terminal as shown.
Check the relay operation.
Out of specification
Replace.
•
Standard charging current is reached
Battery is good.
•
Standard charging current is not reached
Replace the battery.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.
Recommended lubricant
Dielectric grease
