Test Procedures
• Scrape a small amount of paint from starter/generator housing (ground) and use this location when testing
motor terminals to electrical ground.

1. If necessary, see Testing Basics on page 18-14.
2. Disconnect battery and spark plug wire(s). See Disconnecting the Battery – Gasoline Vehicles, Section
1, Page 1-4.
3. Disconnect the wires from all the terminals on the starter/generator. Then place the black (–) probe of a
multimeter, set to 200 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 18-16, Page 18-29). 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 on page 20-1.
– 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.
4. Using a multimeter set to 200 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 on page 20-1.
5. With the wires still disconnected, using a multimeter set on 200 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 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 on page 20-1.
6. With the wires still disconnected, using a multimeter set to 200 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 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 on page 20-1.
Ensure that wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
