STARTER MOTOR - NO-LOAD TEST
The starter No Load Test will identify open or shorted windings and a possible rubbing starter motor armature or bent starter motor armature shaft.

energized. Failure to follow these instructions may result in personal injury.
Connect a fully charged battery, a Starter, Alternator, Battery, Regulator and Electrical (SABRE) Tester and a remote starter switch to the starter
motor. Connect the remote starter switch between the battery positive (+) post and the starter motor S-terminal. Connect the starter motor
