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
(Figure 19-19, Page 19-22) .
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. Turn the key switch to ON position, press the accelerator pedal to 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.
See Test Procedure 11 – Voltage Regulator on
page 19-22. If the voltage does not rise, a tear-down inspection of the starter/generator will be necessary. See
Section 20 – Electrical Components (Gasoline Vehicle).
5. Connect the yellow wire to the DF terminal on the starter/generator.

TEST PROCEDURE 11 – Voltage Regulator
See General Warnings on page 1-2.
NOTE: Keep the battery connected while performing this test procedure.
1. Place the neutral lockout cam in the MAINTENANCE position, put the Forward/Reverse handle in the NEUTRAL
position, and 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 correctly adjusted. See Engine RPM Adjustment on page 22-9.
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 OFF, 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 and white wires crimped together from the voltage regulator attached.
Place the black (–) probe on the negative (–) battery post
(Figure 19-20, Page 19-23) . 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.
See Test Procedure 1 – Battery on page 19-12. 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 20-13.
