When the key is turned on, current flows through the warning lamp, field coils and then to ground causing the lamp to illuminate. Once your engine is running, a higher alternator voltage at the field coils should turn the dashboard lamp off.

When your warning light is “on” basically, it means that there is a significant mismatch between the voltage that the charging system is producing and the battery voltage.

Low output from the alternator or a broken belt could be the reason for this light to come on. Even with a Voltmeter or Amp meter under the dash, it’s a good idea to also have a warning light. Warning lights attract attention immediately. Only with a 3 wire alternator conversion can you make use of a dashboard indicator!
