
NOTE: The ignition switch must be in the ON posi-
tion, the engine stop switch in the RUN position, and
the shift lever in the NEUTRAL position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the starter terminal;
then connect the black tester lead to ground.
3. With the starter button depressed, the meter must
show approximately 10.0 DC volts and the starter
motor should operate.
AR607D

NOTE: If the meter showed correct voltage but the
starter motor did not operate or operated slowly, the
starter motor may be defective or there may be a
mechanical failure preventing the starter motor from
operating.

NOTE: If the meter showed no voltage, inspect ground
connections, starter motor lead, battery voltage (at the
battery), starter motor relay, or the neutral start relay.
REMOVING
1. Disconnect the battery.
2. Remove the nut securing the positive cable to the
starter motor; then remove the cable from the starter
motor.
3. Remove the two cap screws securing the starter
motor to the crankcase; then remove the starter
motor. Account for an O-ring.
INSTALLING
1. Apply a small amount of grease to the O-ring seal on
the starter motor; then install the starter into the
crankcase. Secure with two cap screws making sure
the engine ground is secured by the rear cap screws.
Tighten to 8 ft-lb.
KC201A
2. Secure the positive cable to the starter motor with the
nut. Tighten to 8 ft-lb.
3. Connect the battery.
Starter Relay
1. Remove the battery case access cover; then using the
multimeter set to the DC Voltage position, check the
relay as follows.
2. Connect the red tester lead to the positive battery ter-
minal; then connect the black tester lead to the starter
cable connection on the starter relay. The meter must
show battery voltage.

NOTE: Make sure that the ignition switch is in the
ON position, transmission in neutral, brake lock
released, and the engine stop switch in the RUN posi-
tion.
3. Depress the starter button while observing the multi-
meter. The multimeter should drop to 0 volts, a
“click” should be heard from the relay, and the starter
motor should run.

NOTE: If a “click” is heard and any voltage is indi-
cated by the multimeter, replace the starter relay. If
no “click” is heard and the multimeter continues to
indicate battery voltage, test the neutral start relay.
Electronic Control Module
(ECM)
The electronic control module (ECM) is located above
the radiator under the radiator/electrical access panel.
 NOTE: The ECM is not a serviceable component. If
the unit is defective, it must be replaced.
The ECM is rarely the cause for electrical problems;
however, if the ECM is suspected, substitute another
ECM of the same part number to verify the suspected one
is defective.
Diagnostic Trouble Codes (DTC) can be cleared by fol-
lowing the procedures located in the Diagnostic Trouble
Codes (DTC) sub-section in this section.
CAUTION
Always disconnect the negative battery cable from the
battery first; then disconnect the positive cable.
