Starter No-Load Test

CAUTION: Ensure starter is securely mounted in vise while energizing as starter will move or jump.
  1. Connect starting system test equipment following manufacturer instructions. See Fig 1 . Ensure carbon pile rheostat of starter tester is turned off.
  2. Connect heavy wire between negative battery terminal and starter frame. Connect another heavy wire between positive battery terminal and "B" terminal of starter solenoid.
  3. Connect a jumper wire between terminals "S" and "B" on starter solenoid. See Figure . Ensure starter drive ejects completely and starter spins rapidly. Observe ammeter reading.
  4. If ammeter is not available, note voltage reading while testing. Using carbon pile rheostat, apply load until voltmeter reading is equal to test voltage. Read amperage on starter tester. Replace starter if current draw is more than specified. See STARTER SPECIFICATIONS.
