TEST PROCEDURE 8 – STARTER/GENERATOR (STARTER FUNCTION)
Read DANGER and WARNING on page 11-1.
1. Turn the key switch OFF, place the Forward/Reverse handle in the NEUTRAL position, chock the
wheels and disconnect the battery cables, negative cable (–) first.
2. Check that wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
3. 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 11-33, Page 11-30). 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, Sec-
tion 12, Page 12-2.
- 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.
4. Disconnect the ground wire from the A2 terminal and the green wire from the A1 terminal on the
starter/generator.
5. Using a multimeter set to 200
Ω
(ohms), 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/
generator will need to be removed from the vehicle and disassembled by a qualified technician. See
Starter/Generator Removal, Section 12, Page 12-2.
