  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Prior to the test, check the following items and correct if necessary.

    Check that the battery installed on the vehicle is fully charged
     
    Check the alternator drive belt tension
     
    Turn ignition switch to "OFF"
     
    Disconnect the battery ground cable
     
    Connect a digital voltmeter between the "B" terminal of the alternator and ground by connecting the positive (+) lead of the voltmeter to the "B" terminal of the alternator and connecting the negative (-) lead to good ground or the negative (-) battery terminal
     
    Disconnect the alternator output wire from the alternator "B" terminal
     
    Connect a DC ammeter (0 to 150 Amps) in series between the "B" terminal and the disconnected output wire
     
    Connect the negative (-) lead wire of the ammeter to the disconnected output wire
     
    Attach the engine tachometer and connect the battery ground cable

  4.  
  5. Turn on the ignition switch and check to see that the voltmeter is properly installed and indicates the following value: Voltage reading = Battery voltage of 12.0-14.1 volts.
  6.  
  7. If it reads 0 volts, there is an open circuit in the wiring between the alternator "B" terminal and the battery and the battery negative (-) terminal, or the fusible link is blown.
  8.  
  9. Start the engine keeping all lights and accessories off.
  10.  
  11. Run the engine at a speed of about 2,500 rpm and read the voltmeter when the alternator output current drops to 10 Amps or less.
  12.  
  13. If the voltmeter reading agrees with the value listed in the Regulating Voltage Table below, the voltage regulator is functioning correctly.
  14.  
  15. If the reading is other than the standard value, the voltage regulator or the alternator is faulty.

  18.  
  19. Disconnect the battery ground cable.
  20.  
  21. Remove the voltmeter and ammeter and the engine tachometer.
  22.  
  23. Connect the alternator output wire to the alternator "B" terminal.
