b. Connect a charger and ammeter to the bat-
tery and start charging.
NOTE:
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 overcharged.
c. Make sure that the current is higher than the
standard charging current written on the bat-
tery.
NOTE:
If the current is lower than the standard charging
current written on the battery, set the charging
voltage adjusting dial to 20–24 V and monitor
the amperage for 3–5 minutes to check the bat-
tery.
• 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.
NOTE:
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.

ELECTRICAL COMPONENTS
NOTE:
If the current is lower than the standard charging
current written on the battery, this type of battery
charger cannot charge the MF battery. A vari-
able voltage charger is recommended.
d. Charge the battery until the battery's charg-
ing voltage is 15 V.
NOTE:
Set the charging time to 20 hours (maximum).
e. 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.

6. Install:
• Battery
7. Connect:
• Battery leads
(to the battery terminals)
NOTE:
Route the positive battery lead under the nega-
tive battery lead, making sure not to route it on
top of the relay unit.

CAUTION:
First, connect the positive battery lead "1",
then the negative battery lead "2".

8. Check:
• Battery terminals
Dirt → Clean with a wire brush.
Loose connection → Connect properly.
9. Lubricate:
• Battery terminals
Recommended lubricant
Dielectric grease
