BATTERY INSPECTION
Charging method using a variable voltage charger
Measure the open-circuit
voltage prior to charging.
Connect a charged and
AMP meter to the battery
and start charging.
Make sure that the current
is higher than the standard
charging current written on
the battery.
By turning the charging volt-
age adjust dial, set the charg-
ing voltage at 20 ~ 24 V.
Adjust the voltage so that the
current is at the standard
charging level.
Monitor the amperage for 3 ~ 5
minutes to check if the stan-
dard charging current is
reached.
Set the time according to the
charging time suitable for the
open-circuit voltage.
Refer to “BATTERY INSPEC-
TION”.
If the current does not exceed
the standard charging current
after 5 minutes, replace the
battery.
If charging requires more than 5 hours, it is advisable to check the charg-
ing current after a lapse of 5 hours. If there is any change in the amper-
age, readjust the voltage to obtain the standard charging current.
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.
NOTE:
Voltage should be measured 30
minutes after the snowmobile is
stopped.
NOTE:
Set the charging voltage at 16 ~
17 V. (If the setting is lower,
charging will be insufficient. If too
high, the battery will be over-
charged.)
