Primary Winding
1. Connect the red tester lead to either terminal; then
connect the black tester lead to the other terminal.
2. The meter reading must be within specification.
Secondary Winding
1. Remove the plug cap from the high tension lead;
then connect the red tester lead to the high tension
lead.
2. Connect the black tester lead to the coil frame or
the primary connector.
3. The meter reading must be within specification.
NOTE: If the meter does not show as specified,
replace ignition coil.
Spark Plug Cap
1. Connect the red tester lead to one end of the cap;
then connect the black tester lead to the other end
of the cap.
AR603D
2. The meter reading must be within specification.
NOTE: If the meter does not read as specified,
replace the spark plug cap.
PEAK VOLTAGE
NOTE: All of the peak voltage tests should be made
using the Fluke Model 77 Multimeter with Peak Volt-
age Reading Adapter. If any other type of tester is
used, readings may vary due to internal circuitry.
NOTE: The battery must be at full charge for these
tests.
Primary/CDI
NOTE: The CDI is located under the seat near the
battery.
1. Set the meter selector to the DC Voltage position;
then disconnect the black/yellow and black pri-
mary wires from the coil.
2. Connect the red tester lead to the black/yellow
wire; then connect the black tester lead to the
black wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.
Speed Sensor
NOTE: Prior to testing the speed sensor, inspect the
three-wire connector on the speed sensor for con-
tamination, broken pins, and/or corrosion.
1. Set the meter selector to the DC Voltage position.
2. With appropriate needle adapters on the meter
leads, connect the red tester lead to the voltage
lead (V); then connect the black tester lead to the
ground lead (G).
CD885A
3. Turn the ignition switch to the ON position.
4. The meter must show 6-12 DC volts.
5. Leave the black tester lead connected; then con-
nect the red tester lead to the signal lead (S) pin.
6. Slowly move the ATV forward or backward; the
meter must show 0 and 6-12 DC volts alternately.
NOTE: If the sensor tests are within specifications,
the speedometer must be replaced (see Section 9).
To replace a speed sensor, use the following procedure.
1. Disconnect the three-wire connector from the
speed sensor harness or from the speed sensor;
then remove the Allen-head cap screw securing
the sensor to the sensor housing.
2. Remove the sensor from the sensor housing
accounting for an O-ring.
3. Install the new speed sensor into the housing with
new O-ring lightly coated with multi-purpose
grease; then secure the sensor with the Allen-head
cap screw (threads coated with blue Loctite #242).
Tighten securely.
