Charging method using a constant volt-
age charger
a. Measure the open-circuit voltage prior to
charging.
IP
Voltage should be measured 30 minutes after
the engine is turned off.
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.
IP
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.
IP
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:
• Battery
7. Connect:
• Battery leads
(to the battery terminals)
NOTICE
ECA13630
First, connect the positive battery lead “1”,
and then the negative battery lead “2”.
8. Check:
• Battery terminals
Dirt → Clean with a wire brush.
Loose connection → Connect properly.
9. Install:
• Upper panel
Refer to “GENERAL CHASSIS” on page 4-1.

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 terminal as shown.
Check the relay operation.
Out of specification → Replace.
A. Open-circuit voltage (V)
B. Time (minutes)
C. Charging
D. Ambient temperature 20 °C (68 °F)
E. Check the open-circuit voltage.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.
