5. 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.
6. Connect cables to the proper terminals: positive cable to the
positive terminal (+) and negative cable to the negative terminal (-).
Connect the negative cable last.
SPARK PLUG
The ATV comes equipped with a specifi ed spark plug. See the spe-
cifi cations chart for the correct spark plug. A light brown insulator
indicates that the plug is correct. A white or dark insulator indicates
that the engine may need to be serviced or the carburetor may need
to be adjusted.
Consult an authorized Arctic Cat ATV dealer if the plug insulator is not
a light brown color. To help prevent cold weather fouling, make sure
to thoroughly warm up the engine before operating. To maintain a hot,
strong spark, keep the plug free of carbon.
Before removing the spark plug, be
sure to clean the area around the
spark plug. If you do not, dirt could
enter engine when removing or in-
stalling the spark plug.
Adjust the gap to 0.7-0.8 mm for
proper ignition. Use a feeler gauge
to check the gap.
When installing the spark plug, be
sure to tighten it securely. A new
spark plug should be tightened 1/2
turn once the washer contacts the
cylinder head. A used spark plug
should be tightened 1/8 - 1/4 turn
once the washer contacts the cylin-
der head.
Connecting cables in reverse (positive to negative and negative to
positive) can cause serious damage to the electrical system.
