A cranking motor is designed for intermittent duty only, and should never be
operated for more than 30 seconds at a time. After 30 seconds, the cranking must be
stopped for at least 2 minutes to allow the motor to cool.
Check armature for free rotation of pinion gear.
Tight bearing, a bent armature shaft, or a loose pole shoe screw will cause the armature to
not turn freely. If the armature does not turn freely, replace starter and notify direct support
maintenance. If the armature does turn freely, proceed to step 2 for a no-load test.
Perform a no-load test as follows:
The no-load test may point to specific defects which can be verified with tests when
disassembled. Also, the no-load test can identify open or shorted fields, which are difficult to
check when disassembled. The no-load test also can be used to indicate normal operation on a
repaired motor before installation.
