What are the Signs of a Bad Alternator?
The alternator is a key component in your car's electrical system, turning the energy from the crankshaft into electricity to power your electrical systems and to help the battery recharge. Modern cars are loaded with sensors and computers that all require electricity. From lights to GPS systems, the alternator powers it all. When it starts to fail, it can create a domino effect of electrical problems that can ultimately cause a breakdown.
If you notice starting problems, you will first want to rule out the battery and starter. Have your auto mechanic test them to pinpoint the problem. If you know the signs of a bad alternator, you can have it replaced before it fails completely and avoids being suddenly stranded somewhere.
What are the signs of a bad alternator?
- The dash warning light titled "ALT" or "GEN" will come on and is often the first indicator of an alternator going bad.
- Dimming lights usually mean the alternator is struggling to perform.
- Other electrical systems that are powered by the alternator may start to act up, such as power windows, power locks, dashboard lights, air conditioning, radio, GPS, etc.
- Alternator failure can cause some of the bearings to fail in the engine, creating unusual rattles.
- When the alternator is failing, there might not be enough power in the spark plugs to start the engine, or to keep the engine alive, causing it to stall while running.
- The battery will drain because it is not receiving a charge from the alternator. If you have to replace the battery, be sure to have the alternator inspected to make sure it is sending a charge to the battery.
