Starter No Load Test

NOTE: Make all connections and disconnections of equipment with switch in open position.
  1. To perform test, connect test equipment to starter as shown in Fig 1 .  Close switch and compare RPM, amperage, and voltage readings with specifications. See chart.

    CAUTION: Do not apply voltage greater than specified; excessive voltage may cause armature to throw windings because of excessive speed.

    (1) Includes solenoid.
  2. If current draw and RPM is to specification, condition of starter motor is normal. If test indicates low free speed and high current draw, problem could be too much friction resulting from tight, dirty or worn bearings; shorted armature; or grounded armature or fields.
  3. Failure to operate with high current draw indicates a direct ground in the terminal or fields or frozen bearings. Failure to operate with no current draw indicates an open field circuit, open armature coils or broken brush springs.
  4. Low no load RPM and low current draw indicates high internal resistance due to poor connections, defective leads, dirty commutator. High free speed and high current draw indicates shorted fields.
