Figure 11-34 Check Starter Terminal Continuity
8. With the wires still disconnected, use a multimeter set to 200 Ω (ohms) and place the red (+) probe on
the DF terminal and the black (–) probe on the F1 terminal. The reading should be between 4.5 and 5.5
Ω (ohms). If the reading is incorrect, a possible grounded DF terminal and/or grounded field coil may be
the cause. The starter/generator will need to be removed from the vehicle and disassembled by a qual-
ified technician. See Starter/Generator Removal, Section 12, Page 12-1.
TEST PROCEDURE 9 – WIRE CONTINUITY
See General Warning, Section 1, Page 1-1.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the battery cables as instructed (Figure 11-1, Page 11-5). See WARNING "To avoid unin-
tentionally starting..." in General Warning, Section 1, Page 1-2.
3. To test a wire for continuity, disconnect either end from the electrical component it is attached to.
4. Set the multimeter to 200 Ω (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 – DIODE (GENERATOR CIRCUIT)
See General Warning, Section 1, Page 1-1.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the battery cables as instructed (Figure 11-1, Page 11-5). See WARNING "To avoid unin-
tentionally starting..." on page 1-2.
3. Disconnect the red and white wires of the diode assembly from the solenoid posts, located within the
electrical component box.
3.1. Remove the intake hose to the carburetor at the carburetor intake port and move the hose to allow
easy access to the electrical component box cover.
3.2. Remove the cover retaining screw (5) and electrical component box cover (6) (Figure 11-36,
Page 11-30).
3.3. Remove the lock nuts (7) from the two large solenoid posts and disconnect the diode wires from the
solenoid.
