5-10
RESISTANCE (Trigger Coil)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the blue/yellow wire;
then connect the black tester lead to the
green/white wire. The meter reading must be
within specification.
PEAK VOLTAGE
NOTE: All of the peak voltage tests should be
made using the Fluke Model 73 Multimeter with
Peak Voltage 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.
Stator Coil (Trigger)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the blue/yellow wire;
then connect the black tester lead to the
green/white wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.
Starter Motor
NOTE: The starter motor is not a serviceable
component. If the starter motor does not operate,
see Starter Relay in this section. If the relay tests
normal, replace the starter motor.
REMOVING/INSTALLING
1. Disconnect the battery.
2. Remove the nut securing the positive cable to the
starter; then remove the cable from the starter.
3. Remove the two cap screws securing the starter to
the crankcase; then remove the starter. Account for
the wiring forms and an O-ring.
4. Install the new starter motor.
Starter Relay
VOLTAGE
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the battery supply
terminal (1); then connect the black lead to the
starter terminal (2).
KM458A
3. Turn the ignition switch to the ON position. The
meter must read battery voltage.
NOTE: If battery voltage is not shown on the
meter, troubleshoot the battery connections,
ground connections, and starter cable connec-
tions.
4. With the transmission in neutral, depress the
starter button. There should be an audible “click”
from the starter relay and the meter should show 0
DC volts. If the meter indicates as specified,
replace the starter. If there is no audible click and
meter reads battery voltage, proceed to step 5.
5. Disconnect the two-wire connector on the starter
relay pigtail from the main harness; then on the
harness side, connect the red tester lead to the yel-
low/red wire and the black tester lead to the yel-
low/green wire.
6. With the transmission in neutral, depress the
starter button. The meter must read battery volt-
age. If battery voltage is indicated, replace the
starter solenoid. If no voltage is indicated, trouble-
shoot the gear position switch, starter button, igni-
tion switch, or harness connectors.
CDI Unit
The CDI is located beneath the seat near the battery.
NOTE: The CDI unit is not a serviceable compo-
nent. If the unit is defective, it must be replaced.
! CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
! CAUTION
Always disconnect the negative battery cable from the
battery first; then disconnect the positive cable.
