TESTING

WARNING
This tests must be performed within 3 to 5 seconds to avoid burning out the coil.

Pull-In

Disconnect the field coil lead from the terminal C. Connect the battery to the solenoid switch as shown. See if the clutch pinion gear movement is outward. If the gear does not move perform the hold-in test.

Hold-In

Attach the battery to the starter as shown and with the clutch pinion gear out, disconnect the negative lead from terminal C. Check to make sure the pinion gear stays in the outward position. If the clutch gear returns inwards, perform the clutch pinion gear return test.

Clutch Pinion Gear Return

Disconnect the negative lead from the solenoid body. Check the clutch pinion gear returns inward. If not perform the no-load test.

No-Load

Attach a battery and ammeter to the starter. Check that the starter rotates smoothly and steadily with the pinion gear moving out. Check the ammeter shows the correct current. 90 amps or less at 11.5 volts on gasoline engines and 180 amps or less at 11.0 volts on diesel engines. If not replace the starter.
