Output Current Test: Preparation

  1. Prior to the test, check the following items and correct as necessary.
    1. Check if that the battery installed in the vehicle is in good condition. For details, see "BATTERY ".
      NOTE: The battery that is used to test the output current should be one that has been partially discharged. With a fully charged battery, the test may not be conducted correctly due to an insufficient load.
    2. Check the tension of the generator drive belt. See COOLING SYSTEM .
  2. Turn the ignition switch to "OFF".
  3. Disconnect the battery ground cable.
  4. Disconnect the generator output wire from the generator "B" terminal.
  5. Connect a DC ammeter (0 to 100A) in series between the "B" terminal and the disconnected output wire. Be sure to connect the (-) lead wire of the ammeter to the disconnected output wire.
    NOTE: Tighten each connection securely, as a heavy current will flow. Do not rely on clips.
  6. Connect a voltmeter (0 to 20V) between the "B" terminal and ground. Connect the (+) lead wire to the generator "B" terminal and (-) lead wire to a good ground.
  7. Attach an engine tachometer and connect the battery ground cable.
  8. Leave the engine hood open.
