Output Current Test: Preparation
- Prior to the test, check the following items and correct as necessary.
- Check the battery installed in the vehicle to ensure that it is in good condition.
- The battery that is used to test output current should be one that has been partially discharged. With a fully charged battery, test may not be conducted correctly due to an insufficient load.
- Check tension of the generator drive belt.
- Turn off the ignition switch.
- Disconnect the battery ground cable.
- Disconnect the generator wire from the generator "B" terminal.
- Connect a DC ammeter (0 to 100V) in series between the "B" terminal and the disconnected output wire. Be sure to connect the (-) lead of ammeter to disconnect output wire.NOTE: Tighten each connection securely, as heavy current will flow. DO NOT rely on clips.
- Connect a voltmeter (0 to 20V) between the "B" terminal and ground. Connect (+) lead wire to generator "B" terminal and (-) lead wire to a good ground. See Fig 1 .
- Attach an engine tachometer and connect the battery ground cable.
- Leave the engine hood open.
