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.
