Many times, drivers attribute starting problems to the actual starter. However, the culprit could be a dead battery as a result of a bad alternator. When the alternator is functioning properly, it turns the energy from the crankshaft into electricity to power the electrical system and recharges the battery. Because today’s new vehicles are loaded with sensors and computers, a properly functioning alternator is crucial to provide the electricity they require. In addition to starting problems and a dead battery, a bad alternator means that other systems will stop working too, such as the headlights, navigation system, power windows, radio, etc.
If you’re wondering what are the symptoms of a bad alternator, here are the most obvious signs that you will notice:
- The “ALT” or “GEN” light illuminates the instrument panel.
- Headlights go dim.
- Electrical accessories act strangely or stop working altogether—power windows, locks, air conditioning, radio, GPS, etc.
- The engine bearings can start to go bad, causing unusual noises.
- The spark plugs aren’t receiving enough power to start the car.
- The battery isn’t getting recharged so it dies.
With today’s advanced technology, your mechanic can run a diagnostic on your car to pinpoint the cause of your starting problems fairly easily and quickly. They can determine whether your starting problems are caused by a bad starter, a weak battery, or a failing alternator.
