Output Current Test: Preparation
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. Check the tension of the generator drive belt.
- Check the battery installed in the vehicle to ensure that it is in good condition.
- Turn off the ignition switch.
- Disconnect the battery ground cable.
- Disconnect the generator output wire from the generator "B" terminal.
- Connect a DC ammeter (0 to 150A) 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.
- 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.
- Attach an engine tachometer and connect the battery ground cable.
- Leave the engine hood open.
