Fig. Fig. 1: Starter motor no-load test connections 3. Low free speed and high current draw indicates: Too much friction. Tight, dirty, or worn bushings, bent armature shaft allowing armature to drag. Shorted armature. This can be further checked on a growler after disassembly. Grounded armature or fields. Check further after assembly. 4. Failure to operate with high current draw indicates: A direct ground in the terminal or fields. “Frozen” bearings. 5. Failure to operate with low or no current draw indicates: Open solenoid windings. Open field circuit. This can be checked after disassembly by inspecting internal connections and tracing the circuit with a test lamp. Open armature coils. Inspect the commutator for badly burned bar after disassembly. Broken brush springs, worn brushes, high insulation between the commutator bars of other causes which would prevent good contact between the brushes and commutator. 6. Low no-load speed and low current draw indicates: High internal resistance due to poor connections, defective leads, dirty commutator and causes listed under Step 6. 7. High free speed and high current drain usually indicate shorted fields. If shorted fields are suspected, replace the field and frame assembly. Also check for shorted armature using a growler.
