6. Attach one clamp of the positive
(red) jumper cable to the positive (+)
terminal (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)
jumper cable to the positive (+) ter-
minal (2) of the good battery (B).
 NOTE: Some jumper cables may
be the same color but the clamps
or ends will be color-coded red
and black.
7. Attach one clamp of the negative
(black) jumper cable to the nega-
tive (-) terminal (3) of the good bat-
tery (B); then attach the other
clamp of the negative (black)
jumper cable (4) to an unpainted
metal surface (A) on the engine or
frame well away from the dead bat-
tery and fuel system components.
! WARNING
Never make the final connection to
a battery as a spark could ignite
hydrogen gases causing an explo-
sion of the battery resulting in acid
burns or blindness.
8. Stand well away from the dead
battery and start the vehicle with
the good battery. Allow the vehi-
cle to run for several minutes
applying some charge to the dead
battery.

trical system checked prior to

SPARK PLUG

The ATV comes equipped with a speci-
fied spark plug. See the specifications
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
0744-527
Arctic Cat ATV dealer if the plug insu-
lator 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 installing the
spark plug.
Adjust the gap to 0.7-0.8 mm (0.028-
0.032 in.) for proper ignition. Use a
feeler gauge to check the gap.
