• Standard charging current is reached
Battery is good.
• Standard charging current is not reached
Replace 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 after
a lapse of 5 hours. If there is any change in
the amperage, readjust the voltage to obtain
the standard charging current.
g. Measure the battery open-circuit voltage after
leaving the battery unused for more than 30
minutes.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.

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 bat-
tery and start charging.
c. Make sure that the current is higher than the
standard charging current written on the bat-
tery.
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 charg-
ing 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.

CHECKING THE RELAYS

Check each switch for continuity with the pocket
tester. If the continuity reading is incorrect, re-
place the relay.
1. Disconnect the relay from the wire harness.
2. Connect the pocket tester (Ω × 1) and battery
(12 V) to the relay terminals as shown.
Check the relay operation.
Out of specification → Replace.
