Snowmobile Arctic Cat (2000 year). Manual - part 73

NOTE: For troubleshooting a model that will not

start, attach the analyzer as outlined under section
A. Conduct all of the following tests using the recoil
starter and cranking the engine over hard three
times. Use the specifications called out for 2000
RPM.

NOTE: The individual components must be

checked in the following sequence using the
appropriate specifications chart for recommended
values.

B. CHARGE COIL OUTPUT TEST

1. Perform sub-section A before conducting this

charge coil test.

2. Start the engine and allow it to idle for 4-5 minutes

if not previously done in step A-6. Select the
analyzer VOLT switch position and rotate the
analyzer selector to the CHRG position.

3. Operate the engine at 2000 RPM and observe the

analyzer charge coil reading. The observed reading
must not be less than the recommended value. Next,
observe the analyzer reading at 3000 and 4000
RPM.

4. If any readings are less than the listed values,

disconnect the CDI unit from the system; then using
the recoil starter, crank the engine over hard three to
four times. If the reading is within tolerance for
2000 RPM, the CDI unit may be defective. Repeat
the test once again after connecting the CDI unit
and see if the reading is once again below
specifications at cranking speed. If readings remain
low, replace the CDI unit. If the test results remain
low with the CDI unit disconnected, replace the
charge coil.

NOTE: A defective CDI unit can cause a low

reading for the charge coil output test. To verify
reading, step 4 under Charge Coil Output Test is
very important.

NOTE: The observed readings are permitted to be

greater than (but never less than) the recommended
values.

C. CDI OUTPUT TEST

1. Perform sub-sections A and B before conducting

this CDI test.

2. Rotate the analyzer selector to the CDI position.

3. Operate the engine at 2000, 3000, and 4000 RPM.

If any of the observed CDI readings are less than the
recommended values, replace the CDI unit.

D. LIGHTING COIL OUTPUT TEST

! WARNING

Elevate the snowmobile track with a goad quality
safety stand when performing the lighting coil
output test. Do not allow anyone near the front or
back of the machine while conducting this test.
All safety switches will be bypassed while
conducting the lighting coil output test.

1. Perform sub-section A before conducting this

lighting coil test.

2. Stop the snowmobile engine and disconnect the

snowmobile main wiring harness from the
four-prong analyzer wiring harness connector (the
four-prong analyzer wiring harness connector must
remain connected to the four-prong stator plate
connector).

3. Insert an auxiliary ground wire into the black wire

of the four-wire main harness connector on the
engine side. To stop the engine once it has been
started, touch the auxiliary ground wire to the
engine.

4. Rotate the selector to the LIGHT/TACH position.

5. Operate the engine at 2000, 3000, and 4000 PM. If

any of the observed lighting coil readings are less
than the recommended values, replace the stator
plate lighting coil.

! WARNING

Stop the engine and remove the auxiliary ground
wire before proceeding.

E. VOLTAGE REGULATOR OUTPUT
TEST

! WARNING

Elevate the snowmobile track with a good quality
safety stand when performing the voltage
regulator test. Do not allow anyone near the front
or back of the machine while conducting this
test. All safety switches will be bypassed while
conducting the voltage regulator test.

1. Perform sub-section D before conducting this

voltage regulator test.

2. Disconnect the analyzer wiring harness. Reconnect

all snowmobile electrical connectors to their
original positions.

3. Remove the analyzer from the handlebar and

disconnect the analyzer wiring harness from the
analyzer back-panel connector.

4. Remove the red and black lead wires from their

carrying case. Insert the red lead wire connector
into the analyzer front-panel red jack and the black
lead wire into the black jack.

5. Rotate the selector to the EXT position. Select the

snowmobile HIGH BEAM headlamp position.

6. Insert the analyzer black lead wire into the

headlamp connector on the brown wire position
using the appropriate lead wire end. Insert the
analyzer red lead wire into the yellow wire position.

7. Operate the engine at 3000 to 4000 RPM. The

observed reading must indicate between 30 to 36
volts. If the observed reading is less than 30 volts or
more than 36 volts, replace the voltage regulator.

NOTE: The analyzer is a “peak reading” voltmeter.

Even though the regulator is limiting the system
voltage to about 13 volts RMS (root mean squared),
the analyzer is measuring and displaying voltage
spikes of 30 to 36 volts. These spikes are normal and
do not damage the snowmobile lights. Please
remember that the analyzer will always display the
maximum voltage spike present, not the “average”
voltage that most meters display.

Never use the analyzer front panel lead wires
with the analyzer wiring harness connector
inserted into the analyzer back-panel jack.

NOTE: The Ignition Analyzer can conduct most of

the electrical system performance tests while the
snowmobile is operated in the normal “field”
environment. If the electrical system “breaks down”
after an extended warm-up or only at high speeds,
simply operate the snowmobile until those
conditions are achieved. The rotating selector
switch on the analyzer front-panel (together with the
analyzer’s “multipoint wiring harness”) makes the
analyzer an extremely versatile test instrument.
With the analyzer safely positioned on the
handlebar pad within the operator’s view, the
analyzer is usable under normal operating
conditions.

! WARNING

Elevate the snowmobile track with a good quality
safety stand when performing tests in the shop
area. Do not allow anyone near the front or back
of the machine while conducting these tests.

Check the analyzer wiring harness routing
before starting the engine. Do not allow the
analyzer harness to contact the exhaust system,
driven shaft, clutches, or the drive belt.

6. Start the engine and allow it to idle for about five

minutes. Select the analyzer TACH switch position,
rotate the selector to the LIGHT/TACH position,
and then increase the engine speed to 2000, 3000,
and 4000 RPM. If the snowmobile tachometer is
within 120 RPM of the analyzer reading, the
snowmobile tachometer can be used when
conducting the following tests. If the reading is not
within 120 RPM or if the snowmobile is not
equipped with a tachometer, the analyzer
tachometer must be used to set the following RPM.

7. In many cases, if the tester readings are erratically

flashing high and low numbers, this indicates one of
the following conditions.

A. Defective spark-plug cap - check cap and

replace.

B. Defective high tension lead wire end - cut 6 mm

(1/4 in.) off the end of the wire and install cap.

C. Defective resistor spark plug - install new spark

plug.

Before any further testing can be done, locate the
component causing the erratic readings and replace.
