3. Remove the negative battery cable
and ground wire; then remove the
positive cable.

4. Remove the screw securing the bat-
tery hold-down bracket; then
remove the battery from the snow-
mobile.
5. Thoroughly wash the battery with soap
and water; then using a wire brush,
clean the battery posts and cable ends
removing all corrosive buildup.
Replace damaged cables or cable ends.
NOTE: If battery posts or cable
ends have a build-up of white/green
powder residue, apply water and
baking soda to neutralize acid; then
flush off with warm soapy water.
6. Using a multimeter, test the battery
voltage. The meter must read no less
than 12.8 DC Volts for a fully
charged battery.
NOTE: At this point if the meter
reads as specified, the battery may
be returned to service (see step 9).
7. If the meter reads less than specified
voltage, charge the battery using the
following guidelines:
A. When using an automatic battery
charger, always follow the char-
ger manufacturer’s instructions.
B. When using a constant-current
battery charger, use the follow-
ing Battery Charging Chart.
NOTE: If the battery voltage is 11.5
DC Volts or less, some chargers may
“cut off” and fail to charge. If this
occurs, connect a fully charged
booster battery in parallel (positive
to positive and negative to negative)
for a short period of time with the
charger connected. After 10-15 min-
utes, disconnect the booster battery
leaving the charger connected and
the charger should continue to
charge. If the charger “cuts off,”
replace the battery.
! WARNING
Avoid spillage and contact with skin,
eyes, and clothing.
CAUTION
Do not charge the battery while it is in
the snowmobile with the battery ter-
minals connected.
CAUTION
Do not remove the seal strip on a
sealed battery.
! WARNING
Battery acid is harmful if it contacts
eyes, skin, or clothing. Care must be
taken whenever handling a battery.
CAUTION
Never exceed the standard charging
rate.
! WARNING
An overheated battery could explode
causing severe injury or death.
Always monitor charging times and
charge rates carefully. Stop charging
if the battery becomes very warm to
the touch. Allow it to cool before
resuming charging.
