These sealed batteries after being in ser-
vice require regular cleaning and
recharging in order to deliver peak per-
formance and maximum service life. The
following procedures are recommended
for cleaning and maintaining sealed bat-
teries. Always read and follow instruc-
tions provided with battery chargers and
battery products.
NOTE: Battery maintenance may
be done by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Yamaha Snow-
mobile dealer for this service. This
service is at the discretion and
expense of the snowmobile owner.
To remove and charge the battery, use the
following procedure:
1. Remove the Torx-head screw from
the rear underside of the seat, dis-
connect the seat heater harness (if
equipped) and then remove the seat.
2. Remove the negative battery cable
and ground wire; then remove the
positive cable.
NOTE: For installing purposes
prior to removing the battery, note
the routing and securing locations of
the cables and harness wires.
3. Remove the two screws and lock
nuts securing the battery bracket/
solenoid to the seat-base; then move
the bracket up and out of the way
and remove the battery.

4. 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.
5. Using a multimeter, test the battery
voltage. The meter must read no less
than 12.8 DC Volts for a fully
charged battery.
