TEST PROCEDURE 8 – STARTER/GENERATOR (STARTER FUNCTION)
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. Check that wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
4. Disconnect the wires from all the terminals on the starter/generator. Then place the black (–) probe of a
multimeter, set to
Ω
(ohms), on the starter/generator housing (scratch through the finish to ensure a good
ground). While holding the black probe against the housing, place the red (+) probe (one at a time) on
the A1, A2, F1, F2 and DF terminals respectively (Figure 11-34, Page 11-29). The readings should be
no continuity. If the readings are incorrect, the starter/generator will need to be removed from the vehicle
and disassembled by a qualified technician. See Starter/Generator Removal, Section 12, Page 12-1.
- An incorrect reading from the A1 or A2 terminal indicates three possible problems: 1) a grounded A1
or A2 terminal, 2) a grounded wire in the brush area, or 3) a grounded armature/commutator.
- If the F1 or F2 reading is incorrect, it indicates a possible grounded F1 or F2 terminal or a grounded
field coil.
- If the DF reading is incorrect, it indicates a possible grounded DF terminal or a grounded field coil.
5. Disconnect the ground wire from the A2 terminal and the green wire from the A1 terminal on the starter/
generator.
6. Use a multimeter set to 200
Ω
(ohms) and place the red (+) probe on the A1 terminal and the black (–)
probe on the A2 terminal. The reading should be continuity. If the reading is incorrect, a possible open
or poor contact in a brush assembly and/or open armature windings may be the cause. The starter/gen-
erator will need to be removed from the vehicle and disassembled by a qualified technician. See Starter/
Generator Removal, Section 12, Page 12-1.
7. With the wires still disconnected, and a multimeter set on 200
Ω
(ohms), place the red (+) probe on the
F1 terminal and the black (–) probe on the F2 terminal. The reading should be between approximately
0.1 and 0.3
Ω
(ohms). If the reading is incorrect, a possible open field coil or bad connections at terminals
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 12-1.
