What does it mean when amp light comes on?

When the amp light comes on in a vehicle, it typically indicates a problem with the charging system, often related to the alternator not supplying enough power to the battery. This could be due to a faulty alternator, a damaged battery, or issues with wiring and connections. If the light remains on, it's important to have the vehicle inspected promptly to avoid potential breakdowns. Ignoring it could lead to a drained battery and ultimately leave you stranded.
