Diagnosis & Testing



The easiest way to test the performance of the alternator is to perform a regulated voltage test.
  1. Start the engine and allow it to reach operating temperature.
  2. Connect a voltmeter between the positive and negative terminals of the battery.
  3. Voltage should be 14.1-14.7 volts.
  4. If voltage is higher or lower than specification, connect a voltmeter between the battery positive (B+) voltage output terminal of the alternator and a good engine ground.
  5. Voltage should be 14.1-14.7 volts.
  6. If voltage is still out of specification, a problem exists in the alternator or voltage regulator.
  7. If voltage is now within specification, a problem exists in the wiring to the battery or in the battery itself.
    NOTE
    Many automotive parts stores have alternator bench testers available for use by customers. An alternator bench test is the most definitive way to determine the condition of your alternator.
