7. With the wires still disconnected, using a multimeter set to 200
Ω
(ohms), 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
qualified technician. See Starter/Generator Removal, Section 12, Page 12-2.
TEST PROCEDURE 9 – WIRE CONTINUITY
Read DANGER and WARNING on page 11-1.
1. Place the Forward/Reverse handle in the NEUTRAL position, chock the wheels and disconnect the bat-
tery, negative cable first.
2. To test a wire for continuity, disconnect either end from the electrical component it is attached to.
3. 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)
Read DANGER and WARNING on page 11-1.
1. Place the Forward/Reverse handle in the NEUTRAL position, chock the wheels, and disconnect the
battery, negative (–) cable first.
2. Disconnect the two wires from the diode assembly, which is located on the I-beam close to the battery.
