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.
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 at 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.

CHECKING THE RELAYS
Check each switch for continuity with the pocket
tester. If the continuity reading is incorrect, re-
place the relay.
Pocket tester
90890-03112
Analog pocket tester
YU-03112-C
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.
