Test Procedures

TEST PROCEDURE 9 – Wire Continuity
See General Warning on page 1-1.
1.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery – Gasoline Vehicles, Section
2.
To test a wire for continuity, disconnect either end from the electrical component it is attached to.
3.
Set the multimeter to 200 ohms and place the red (+) probe on the terminal at one end of the wire. Place the
black (–) probe on the other terminal end of the wire. The reading should be continuity. If the reading is incorrect,
repair or replace the wire.
TEST PROCEDURE 10 – Starter/Generator (Generator Function)
See General Warning on page 1-1.
NOTE:
Keep the battery connected while performing this test procedure.
1.
Place the Forward/Reverse handle in the NEUTRAL position and the neutral lockout switch in the MAINTENANCE
position. Chock the wheels.
2.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
3.
Disconnect the yellow wire from the DF terminal on the starter/generator. Cover the connector on the yellow wire
to make sure the yellow wire will not short to ground. Then, using a jumper wire, ground the DF terminal to the
A2 terminal
4.
Using a multimeter set to 20 volts DC, place the red (+) probe on the positive (+) post of the battery, and place the
black (–) probe on the negative (–) post. Start the engine and run it at full governed speed. The reading should
show the voltage rising on the meter. If the voltage rises above 15.3 volts DC, test the voltage regulator.
Voltage Regulator on page 12-19.
If the voltage does not rise, a tear-down inspection of the starter/generator
will be necessary.
See Starter/Generator Removal on page 14-1.
5.
Connect the yellow wire to the DF terminal on the starter/generator.
TEST PROCEDURE 11 – Voltage Regulator
See General Warning on page 1-1.
NOTE:
Keep the battery connected while performing this test procedure.
1.
Place the Forward/Reverse handle in the NEUTRAL position and the neutral lockout switch in the MAINTENANCE
position. Chock the wheels.
2.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
3.
Check the engine RPM setting to ensure that it is adjusted correctly.
See Engine RPM Adjustment on page
4.
With the battery in good condition and fully charged, run the engine for several minutes to bring the voltage
regulator to operating temperature.
5.
Turn the key switch to the OFF position, killing the engine. Using a multimeter set to 20 volts DC, place the red
(+) probe on the large post of the solenoid with the red wire from the voltage regulator attached. Place the black
(–) probe on the negative (–) battery post
. Turn the key switch to the ON position.
Press the accelerator to start the engine and run it at full governed speed. If the reading is between 14.7 and 15.3
volts, the regulator is good. If the reading is lower than 14.7 volts but rising steadily, check battery condition. If the
reading is lower than 14.7 volts and not rising, and the starter/generator is good; or if the reading is over 15.3
volts and continues to rise, replace voltage regulator.
See Voltage Regulator Removal on page 14-12.
