Explosive hydrogen gas, which escapes during charging,
could cause death or serious injury. Charge battery in a
well-ventilated area. Keep open flames, electrical sparks
and smoking materials away from battery at all times.
KEEP BATTERIES AWAY FROM CHILDREN. (00065a)
If battery releases an excessive amount of gas during
charging, decrease the charging rate. Overheating can
result in plate distortion, internal shorting, drying out or
damage. (00413b)
1. Perform a voltmeter test to determine the state of charge.
See the electrical diagnostic manual. If battery needs to
be charged, proceed to the next step.
NOTE
The figures listed in the table below show typical charging
times. Charge times may vary. When using an appropriate
automatic charger, allow the charger to determine when char-
ging is complete.

NOTE
Do not use battery chargers that produce excessively high
voltage designed for flooded batteries or excessively high
current designed for much larger batteries. Charging should
be limited to no more than 5 amps at no more than 14.6 volts.
Unplug or turn OFF battery charger before connecting
charger cables to battery. Connecting cables with charger
ON can cause a spark and battery explosion, which could
result in death or serious injury. (00066a)
Do not reverse the charger connections described in the
following steps or the charging system of the motorcycle
could be damaged. (00214a)
2. Connect red battery charger lead to the positive (+) ter-
minal and black battery charger lead to the negative (-)
terminal of the battery.
NOTE
If the battery is still in the vehicle, connect the negative lead
to the chassis ground. Be sure that the ignition and all electrical
accessories are turned off.
3. Step away from the battery and turn on the charger. See
the charging instructions in
Table 1-12 .
Unplug or turn OFF battery charger before disconnecting
charger cables from battery. Disconnecting clamps with
charger ON can cause a spark and battery explosion, which
could result in death or serious injury. (00067a)
4. After the battery is fully charged, turn the charger OFF
and disconnect the black battery charger lead to the neg-
ative (-) terminal of the battery.
5. Disconnect the red battery charger lead to the positive (+)
terminal of the battery.
6. Mark the charging date on the battery.
7. Perform either a conductance test or load test to determine
the condition of the battery. See the electrical diagnostic
manual.
8. If charging a battery because voltmeter test reading was
below 12.6 V, perform voltmeter test. See the electrical
diagnostic manual.
BATTERY INSTALLATION AND
CONNECTION
1. Place the fully charged battery in the mounting position,
terminal side to the rear of motorcycle.
2. Hook rubber strap around body of battery.
