GM 10465023 Starter, (Remanufacture)

Finally, install each of the wires to the solenoid terminals using your identification coding.

Install the thrust collar on the shaft with the shoulder next to the snap-ring. Squeeze the thrust collar and stop/retainer together until the snap-ring fully enters the retainer.

Next, remove the commutator end-frame, field frame assembly, and armature from the drive housing.

Run the engine until it reaches normal operating temperature, then shut it off and disconnect the coil to distributor LT wire or 'BAT' connection on HEl distributors to prevent firing during cranking. Connect a voltmeter positive lead to the starter motor terminal of the solenoid and the negative lead to ground. Actuate the ignition switch and take voltmeter readings as soon as a steady figure is indicated, avoiding more than 30 seconds of starter motor operation at a time.

The air cleaner and duct assembly, if necessary. On the 3800, the upper mounting bracket, cooling fan, and oil cooler lines from the radiator may also need to be removed.

To test the starter motor's performance with a voltmeter, run the engine until it reaches normal operating temperature, then disconnect the coil wire from the distributor cap and ground it on the engine. Connect a voltmeter positive lead to the positive battery post and the negative lead to the negative post. Crank the engine and take voltmeter readings as soon as a steady figure is indicated, not exceeding 15 seconds of starter motor turning. A reading of 9 volts or more at normal cranking speed is normal. If the cranking speed is slow and the reading is less than 9 volts, it could indicate various issues like burned solenoid contacts, a bad starter motor, discharged battery, or a bad connection.
