Test Procedures
TEST PROCEDURE 11 – Starter/Generator (Generator Function)
See General Warnings on page 1-1.
NOTE: This is a voltage test.
1.
If necessary, see Testing Basics on page 18-15.
2.
Place the Forward/Reverse handle in the NEUTRAL position and the neutral lockout switch in the MAINTENANCE
position. Chock the wheels.
3.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
4.
Disconnect yellow wire from DF terminal on starter/generator. Cover terminal on yellow wire to make sure it will
not short to ground. Then, using a jumper wire, ground DF terminal to A1 terminal (Figure 18-16, Page 18-32).
5.
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. See
Voltage Regulator on page 18-34. If the voltage does not rise, a tear-down inspection of the starter/generator
will be necessary. See Starter/Generator Removal on page 20-1.
6.
Remove jumper wire.
7.
Reconnect yellow wire to DF terminal on starter/generator.

TEST PROCEDURE 12 – Starter/Generator (Starter Function)
See General Warnings on page 1-1.
NOTE: Observe the following before testing the starter/generator:
• This is only testing continuity.
• Tag the starter/generator wires for identification before disconnecting.
• Remove starter/generator wire from one of the "A" terminals and one of the "F" terminals if testing while
starter/generator is in vehicle.
