Ammeter
June 1, 2006 by Alborz Fallah
Found mostly in older cars, the Ammeter is used to determine whether the electrical system is charging, discharging, or staying “level”. The gauge should dip when the engine is started (as the engine uses more power to start), then go up as the alternator re-charges the battery. After a few minutes, it should go to its middle position.
