TEST PROCEDURE 9 – WIRE CONTINUITY
See General Warning, Section 10, Page 10-1.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning, Section 10, Page 10-1.
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, Section 10, Page 10-1.
NOTE:
Keep the battery connected while performing this test procedure.
1. Place the neutral lockout cam in the SERVICE (MAINTENANCE) position, put the Forward/Reverse han-
dle 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. Disconnect the yellow wire from the DF terminal on the starter/generator. Cover the connector on the yel-
low 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 11-13, Page 11-17)
.
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 accel-
erator 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 Proce-
dure 11 – Voltage Regulator on page 11-18.
If the voltage does not rise, a tear-down inspection of the
starter/generator will be necessary.
See Starter/Generator Removal, Section 12, Page 12-1.
5. Connect the yellow wire to the DF terminal on the starter/generator.
