To wire a one-wire alternator on a diesel farm tractor, first ensure the engine is off and the battery is disconnected for safety. Connect the single output terminal of the alternator to the positive terminal of the battery.

Finally, reconnect the battery and start the engine to verify that the alternator is charging correctly.
