Stator Coil

VOLTAGE
(AC Generator - Regulated Output)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the positive battery
post; then connect the black tester lead to the nega-
tive battery post.
3. With the engine running at a constant 3000 RPM
(with the headlights on), the meter must show 14-
15.5 DC volts.
CAUTION
Do not run the engine at high RPM for more than 10 sec-
onds.
 NOTE: If voltage is lower than specified, test AC
Generator coil - no load.
VOLTAGE (AC Generator Coil - No
Load)
The connector is the black three-pin one on the right side
of the engine just above the starter motor.
 NOTE: Test the engine-side of the connector.
1. Set the meter selector to the AC Voltage position.
2. Test between the three black wires for a total of three tests.
3. With the engine running at the specified RPM, all
wire tests must show 60 AC volts.
CAUTION
Do not run the engine at high RPM for more than 10 seconds.
 NOTE: If both AC Generator coil tests failed, check
all connections, etc., and test again. If no voltage is
present, replace the stator assembly.
RESISTANCE (AC Generator Coil)
1. Set the meter selector to OHMS position.
2. Test between the three black wires for a total of three tests.
3. The meter reading must be within specification.
RESISTANCE (Crankshaft Position
Sensor)
1. Disconnect the gray four-pin connector on the right
side of the engine just above the starter motor.
2. Set the meter selector to the OHMS position.
3. Connect the red tester lead to the green wire; then
connect the black tester lead to the blue wire. The
meter reading must be within specification.
 NOTE: The battery must be at full charge for this test.

VOLTAGE (Crankshaft Position
Sensor)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the green wire; then
connect the black tester lead to the blue wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.
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 position.
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 indi-
cate battery voltage, test the neutral start relay.

Starter Motor

 NOTE: The starter motor is a non-serviceable com-
ponent. If the following test does not result as speci-
fied, the starter motor must be replaced.
TESTING VOLTAGE
Perform this test on the starter motor positive terminal.
To access the terminal, slide the boot away.
 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.
