MAINTENANCE

Removing/Installing Spark
Plugs (2-Stroke Models)

1. Remove the spark plug caps

from the plugs.

2. Using a spark plug wrench,

remove the plugs.

3. Install the plugs and finger-

tighten.

4. Tighten the spark plugs to 2.5-

2.8 kg-m (18-20 ft-lb); then

install the spark plug caps.

Removing/Installing Spark
Plugs (660 cc Models)

1. Remove the spark plug/coil

cover.

2. Remove the cap screws secur-

ing the spark plug coils to the

engine; then remove the coils.

3. Using a spark plug wrench,

remove the plugs.

4. Install the plugs and finger-

tighten.

5. Tighten the spark plugs to 2.1

kg-m (15 ft-lb); then install the

spark plug coils and secure

them with cap screws.

6. Install the spark plug/coil cover.

Checking Spark Plugs
(2-Stroke Models)

To see if the spark plugs being used

are of the proper heat range (after

the snowmobile has been operated

under normal driving conditions),

remove the spark plugs and exam-

ine the condition of the center elec-

trode insulator of each spark plug.

AO352A

A. TAN or LIGHT BROWN

insulator indicates correct

spark plugs (heat range).

B. LIGHT GRAY or WHITE

insulator indicates over-

heating of the engine. This

condition is caused by a too

lean condition or incorrect

spark plugs (heat range too

hot).

C. BLACK insulator indicates

fuel in the combustion

chamber is not burning

completely. This condition

is caused by a too rich

condition, too much oil, or

incorrect spark plugs (heat

range too cold).



NOTE: If the center electrode

insulators are light gray, white, or
black and if the carburetor adjust-
ments (on carbureted models),
oil-injection pump synchroniza-
tion, and ignition timing are cor-
rect, different heat-range spark
plugs may be necessary. Autho-
rized Arctic Cat Snowmobile deal-
e rs h av e d e t a i l e d sp a r k p l u g
information. Consult a dealer
before changing spark plugs, as
incorrect heat-range spark plugs
could cause poor engine perfor-
mance or engine damage.

MAINTENANCE

CHARGING BATTERY (Electric
Start Models)

Standard with Removable Caps



NOTE: The level of the battery

fluid must be kept between the
MAX and MIN level lines at all
times. If the level drops below the
MIN level line, add only distilled
water until it reaches MAX level
line.

To remove and charge the battery,

use the following procedure:

1. Remove the negative battery

cable; then remove the positive

cable and the battery vent tube.

Remove the battery from the

snowmobile. Care should be

taken not to damage the vent

tube.

2. Remove the vent plugs; then (if

necessary) fill the battery with

distilled water to the MAX

level indicated on the battery.

3. Trickle charge the battery at 1.4

amps for 10 hours.

4. After charging, check fluid

level and fill with distilled

water as necessary; then install

vent plugs.

! CAUTION

If a spark plug is light gray,
white, or black and another is
tan or light brow n, take the
snowmobile to an authorized
Arctic Cat Snowmobile dealer
for inspection and service. If not
under warranty, this service is at
the discretion and expense of
the snowmobile owner.

! WARNING

Battery acid is harmful if it con-
tacts eyes, skin, or clothing.
Care must be taken whenever
handling a battery.

! WARNING

Any time service is performed
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 cloth-
ing when handling batteries.
W h e n s e r v i c i n g b a t t e r y i n
enclosed space, keep the area
well-ventilated. Make sure bat-
tery venting is not obstructed.

! WARNING

Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the state of California
to cause cancer and reproduc-
tive harm. Wash hands after
handling.

! 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 terminals connected.

! CAUTION

N ev e r e x c e e d t h e s t a n d a rd
charging rate.

! CAUTION

Before installing the battery,
make sure the ignition switch is
in the OFF position.

MAINTENANCE

5. Place the battery into position

in the snowmobile and secure.

6. Attach the vent tube and check

the vent tube to make sure it is

not crimped or obstructed in

any way and that it is properly

routed.

7. Clean the battery posts and

cable ends by using a battery

post cleaning tool and/or a wire

brush to remove dirt, grease,

and corrosion.

8. Connect cables to the proper

terminals: positive cable to the

positive terminal (+) and nega-

tive cable to the negative termi-

nal (-). Connect the negative

cable last.

Sealed with Cap Strip

1. Remove the battery from the

snowmobile.



NOTE: This battery is perma-

nently sealed. There is no need to
remove the caps or to add elec-
trolyte for the life of the battery.



NOTE: Do not charge the bat-

tery while it is in the snowmobile
with the battery cables connected
as damage to the electrical sys-
tem may occur.

2. Using Arctic Cat Battery

Charger (p/n 0436-634), charge

the battery until the indicator

light on the charger illuminates.



NOTE: Once charged, the bat-

tery can be left connected to the
charger indefinitely.

3. Place the battery into position

in the snowmobile and secure.

4. Connect cables to the proper

terminals: positive cable to the

positive terminal (+) and nega-

tive to the negative terminal (-).

Connect the negative cable last.

! CAUTION

Connecting cables in reverse
(positive to negative and nega-
tive to positive) can cause seri-
ous damage to the electrical
system.

! CAUTION

This maintenance-free battery
requires periodic charging to
prevent sulfiding. If the snow-
mobile will be idle for extended
periods of time, either run the
engine or trickle charge from
time to time. If the battery com-
pletely discharges, permanent
damage will occur requiring
replacement.

! WARNING

Always wear safety glasses
when connecting or disconnect-
ing a battery charger. Do not
smoke or allow open flames
near a charging battery.

! CAUTION

Improper activation or exces-
sive overcharging (possibly by
equipment failure) could cause
damage to the battery or snow-
mobile by forcing acid out of the
safety valve.

! CAUTION

Connecting cables in reverse
(i.e. positive to negative and
negative to positive) can cause
serious damage to the electri-
cal system.

MAINTENANCE

FUSES (660 cc Models)

Fuses protect the snowmobile elec-

trical system from overloading. If

electrical parts in the snowmobile

are not working, the system may

have been overloaded and caused a

blown fuse. Before repairing or

replacing any electrical part, check

the appropriate fuses. The following

illustration shows which fuse pro-

tects each electrical part on the

snowmobile. If a fuse blows (opens

a circuit), all the parts of the snow-

mobile that use that circuit will not

work.

736-448A

Once which fuse to check has been

determined, perform the following

steps:

1. Open the hood and remove the

fuse panel cover. The fuse panel

is located on the right side of

the engine compartment near

the battery (for standard mod-

els) or behind the intake mani-

fold (for Turbo models).



NOTE: There is a fuse pulling

tool along with spare fuses inside
the fuse panel.

AO352A

2. Remove the suspected fuse.
3. Look through the clear side of

the fuse to see if the metal wire

inside is separated. If it is, the

fuse is blown and should be

replaced with a fuse of the cor-

rect amperage rating.

4. Install the fuse panel cover.

Even after replacing a fuse, it may

continue to blow if the cause of the

overload is not determined. If the

fuse continues to blow, take the

snowmobile to an authorized Arctic

Cat Snowmobile dealer for service.

If not under warranty, this service is

at the discretion and expense of the

snowmobile owner.

! WARNING

Always replace a fuse with one
h a v i n g t h e s a m e s p e c i f i e d
amperage rating. Using a fuse
with a higher rating can cause
severe wire damage and could
start a fire.
