The battery light is on continuously in your 2001 Ford F-150 because the alternator is not generating enough voltage to charge the battery. The most likely cause is a failing alternator that needs to be replaced. Before replacing it, you can check the voltage at the battery terminals while the vehicle is running. If the voltage is above 14 volts as it should be, then the issue may be corroded battery cables rather than a faulty alternator. Remember, the battery light indicates a problem with the charging system or its components in general.

The initial action is to verify if the alternator is functioning properly by testing the battery voltage while the engine is running. If the voltage is sufficient, proceed to unplug the 3-pin alternator connector. Next, turn the key to see if the warning light remains illuminated. If the light doesn't stay on, the issue lies with the alternator. However, if the light remains on, the problem may be related to the battery or the wiring.
