TROUBLESHOOTING TABLES

NO SPARK

No Spark Condition

Disconnect the single black (black/white) wire from
the CDI Module to the ignition kill circuit. Does it have
a spark?



Check the ignition switch, wire harness, throttle safety
switches and kill switch for proper adjustment or short
to ground. Repair or replace as necessary.

YES



Disconnect the stator to CDI module wires. Test the
resistance values of the stator coils as per the wiring
diagrams. Are the resistance values within specs?



If the parts of the ignition system under the flywheel
check OK, the only remaining component is the coil/
CDI module assembly. Replace the module with
another with the same number.

YES



Isolate which component's resistance is not within
specs. Remove the flywheel and stator. Recheck the
resistances; look for pinched or bare harness wires; or
replace the coil.

Incorrect Timing (Advanced/Retard)

Follow the engine timing procedure for checking
running timing at recommended RPM. Is the timing
within limits?



Adjust the ignition timing by rotating the stator plate to
correct the timing. After adjusting the recommended
RPM timing, continue with operating RPM timing if
poor performance exists. (Continue on with left
column.)

YES



Remove the ignition kill circuit by disconnecting the
single black wire between the CDI module and the
machine harness. Is the timing now correct?



Check the ignition switch, throttle safety switches, kill
switch and harness for damage which can cause
intermittent shorting problems. Correct the problem.

YES



Verify the correct CDI module by comparing the CU
code on the box to the information listed in the ignition
data charts at the beginning of this section. Is it the
right module?



Replace the module with the correct part and readjust
the ignition timing.

YES



Check the resistance of the coils under the flywheel.
Compare these to values on wiring diagram. Are they
within limits?



Check the wiring connecting the coils and/or replace
the coils as necessary.

ELECTRONIC REVERSE (PERC)

Operation

Ensure that the vehicle is stopped and the engine is
warmed up and running at idle.

NOTE: PERC will not engage below 900 RPM or above
4000 RPM.

Push and release the yellow reverse button on the left
hand control. The reverse light on the instrument
panel will flash when engine is in reverse motion.

NOTE: The engine will automatically reduce RPM and
it will reverse the rotation of the engine when the RPM
is at the lowest RPM point.

Ensure that the path behind the snowmobile is clear.

Slowly apply throttle until the sled starts to move in
reverse. Carefully direct the sled in the desired
direction.

NOTE: If the engine stops running or is shut off while
in reverse. The engine will start in forward gear.

FORWARD OPERATION

Ensure that the path ahead is clear, then push and
release the reverse button. The engine will
automatically change direction form reverse to
forward and the reverse light on the instrument panel
will stop flashing.

NOTE: When servicing clutches, ensure the driven
clutch is rotated forward. If not, damage to the driven
clutch may occur when removing the belt.

Altitude Setting

At elevations over 6,000 feet (1,829 meters), the engine
requires a different ignition RPM setting to improve the
operation of the reverse system.

To set the altitude settings:

With the engine running, push and hold the reverse
button for 5 - 6 seconds and then release the button.

The reverse light will flash rapidly on the instrument
panel.

To go back to the low elevation setting, repeat step 1.
The reverse light will flash slowly indicating the system
is in the lower elevation setting.

NOTE: The elevation setting will be set in the memory
(engine running or not) until it is changed.

Important Notes

• Max RPM for shifting into reverse = 4000 RPM

• Max RPM for operating in reverse = 6000 RPM

• Engine must first reach 900 RPM at start up before

the reverse system can be used.

• Flashing light on the instrument panel indicates

that the system is in reverse. On carbureted units
a slow flash indicates that the system is set for low
elevation, and a fast flash indicates the system is
set up for high elevation. Push and hold the
reverse button for longer than 5 seconds to toggle
back and forth from high and low elevation
settings.

• If engine is shut off or dies in forward or reverse

gear, the engine when started will automatically be
in forward gear.

• When servicing clutches, ensure that the vehicle is

in the forward gear.

WARNING

Reverse operation, even at low speeds, may cause

loss of control, resulting in serious injury or death. To

avoid loss of control, always:

LOOK BEHIND BEFORE AND WHILE BACKING.

AVOID SHARP TURNS.

SHIFT TO OR FROM REVERSE ONLY WHEN

STOPPED.

APPLY THROTLE SLOWLY.

CAUTION

To avoid personal injury and/or engine damage, do not

operate the electric start or recoil while engine is

running.

HAND/THUMB WARMERS

Thumb Warmer Diagnostics

The thumb warmer on all Polaris snowmobiles is a
thermistor-type warming element pad. This means its
resistance will change based on temperature.

Hand Warmer Diagnostics

There are two types of hand warmer element pads used
on Polaris snowmobiles. One version is used on steel/
painted handlebars and touring model rear passenger
grab bars, while the other is used on aluminum (Pro Taper)
handlebars. The difference between the two hand warmer
element pads is in the resistance values. A lower
resistance element pad is used on aluminum bars
because aluminum dissipates heat faster than steel.

A common misconception with Polaris hand warmer
elements is the higher resistance circuit is the high
temperature element. In reality, the hand warmer circuit
with the least amount of resistance will flow more current,
and thus create more heat. This is an important fact that
must be taken into consideration when performing
resistance checks on a set of hand warmers.

For example, if a customer has a concern that the left hand
warmer appears to be cooler than the right, the technician
should compare the resistance readings of each pad to the
specifications, and then between the left and right pads. If
the resistance of the left pad is significantly higher than
that of the right, more current will flow to the right side.
While more common reasons for this can be attributed to
how the customer holds the bar in their hands (fingers on
brake lever and not wrapped around grip, etc.), there may
be instances where comparing the left and right hand
warmer resistance values may resolve the customer's
concern.

Another issue is when one or both of the element circuits
shorts to the handlebar itself. This can occur either
because the pad was improperly installed, solder breaks,
or if the grip moves on the bar.

Hand Warmer Resistance Checks

NOTE: Hand warmer pads do not feature a high
temperature circuit. On snowmobiles featuring a left-
hand control, high temperature is achieved by
supplying power to both the low and medium circuits.
On snowmobiles featuring console-mount controls,
the medium circuit is the high temperature circuit.
