Battery
It is extremely important that the battery
be maintained at full charge at all times
and that the battery connections be clean
and tight. If charging the battery becomes
necessary, refer to Battery sub-section in
the Maintenance section.
CAUTION
Always turn the ignition switch key to
the OFF position when the snowmo-
bile is not being used. Leaving the
ignition switch in the ON position will
result in discharging the battery and
possible damage to the battery.
Jump-Starting
NOTE: Yamaha does not recom-
mend jump-starting a snowmobile
with a dead battery but rather to
remove the battery, service it, and
correctly charge it; however, in an
emergency, it may be necessary to
jump-start a snowmobile. If so, use
the following procedure to carefully
and safely complete this procedure.
! WARNING
Improper handling or connecting of a
battery may result in severe injury
including acid burns, electrical burns,
or blindness as a result of an explo-
sion.
Always
watches. Any time service is per-
formed on a battery, the following
must be observed: keep sparks, open
flame, cigarettes, or any other flame
away. Always wear safety glasses.
Protect skin and clothing when han-
dling a battery. When servicing a bat-
tery in an enclosed space, keep the
area well-ventilated.
NOTE: To access the battery, the
seat must be removed.
1. For the snowmobile to be jump-
started, slide any terminal boots away.
2. Inspect the battery for any signs of
electrolyte leaks, loose terminals, or
bulging sides. Leaking or bulging
battery cases may indicate a frozen
or shorted battery.

! WARNING
If any of these conditions exist, DO
NOT attempt to jump-start, boost, or
charge the battery. An explosion
could occur causing serious injury.
3. Inspect the snowmobile to be used for
jump-starting to determine if voltage
and ground polarity are compatible.
The vehicle must have a 12-volt DC,
negative ground electrical system.
Always make sure the electrical sys-
tems are of the same voltage and
ground polarity prior to connecting
jumper cables. If not, severe electri-
cal damage may occur.
4. Move the vehicle to be used for the
jump-start close enough to ensure
the jumper cables easily reach; then
set and lock the brakes, shut off all
electrical accessories, and turn the
ignition switch OFF.
NOTE: Make sure all switches on
the snowmobile to be jump-started
are turned OFF.
5. Disconnect all external accessories
such as cell phones, GPS units, and
radios on both vehicles.
and
Failure to disconnect electronic acces-
sories during jump-starting may cause
system damage due to power spikes.
6. Attach one clamp of the positive
(red) cable to the positive (+) termi-
nal (1) of the dead battery (C) being
careful not to touch any metal with
the other clamp; then attach the
other clamp of the positive (red)
cable to the positive (+) terminal (2)
of the good battery (B).
