Starter Assembly
CAUTION:
These tests must be performed within 3 to 5 seconds of application of power to avoid burning out the coil.
- Remove the terminal "C" nut and disconnect the field coil lead wire from terminal "C".
- Pull-In Coil Test - Connect the battery positive voltage to the magnetic switch (Terminal 50), clip ground to terminal "C" and the main body of the starter. Ensure that the clutch pinion gear moves outward. See Fig 1. If pinion gear does not extend, replace magnetic switch. If operation is as specified, go to step 3.
- Hold-In Coil Test - Disconnect the negative lead from terminal "C". See Fig 2. Verify that the pinion gear remains out. If pinion gear returns, replace magnetic switch. If operation is as specified, go to step 4.
- Pinion Gear Return Test - Disconnect the negative lead from the switch body. See Fig 3. Verify that the clutch pinion gear returns inward. If pinion gear does not return, replace magnetic switch. If operation is as specified, go to step 5.
- Connect the lead wire to terminal "C" with the terminal "C" nut. Tighten the nut to specification. See TORQUE SPECIFICATIONS . Go to step 6.
- No Load Test - Secure the starter in a vise or equivalent to prevent it from rotating. Connect an ammeter in series with battery positive to terminal 30, ensuring these leads are not grounded, connect a jumper wire from terminal 30 to terminal 50. Clip battery negative to the main body of the starter. See Fig 4. Verify the current is within specification of 90 amps with 11.5 volts or less.
