If your alternator is malfunctioning, you might not be able to start your car initially. A faulty alternator can’t charge the battery, even if the engine is running. When a car alternator starts to fail, you may notice several symptoms. One common sign is dim headlights while driving, indicating electrical issues.
Another indicator is the appearance of a dash light shaped like a battery, often referred to as the battery light. This light alerts the driver to check the charging system, as the alternator isn’t charging enough for the electrical system.
Undercharged car batteries are often due to car accessories being left on overnight.
When the charging system works correctly, the charge indicator lamp will light up when you turn on the ignition and go off after starting the car. If the lamp doesn’t appear when you turn the key, you might need to replace the bulb or check the warning light circuit.
However, starting your car with a dead battery and a bad alternator is still possible. You’ll need to jump-start your car using another vehicle with a good battery.
The cost of an alternator varies significantly based on the vehicle’s make and model, the alternator’s brand, and where you purchase it. On average, a new alternator can range from $500 to $700. More common vehicles, such as high-end or specialty vehicles, might see prices on the higher end of the spectrum. Refurbished or remanufactured alternators are also available at a lower cost, usually between $250 and $400. Labor costs for installation, if you are not doing it yourself, can add another $100 to $200 depending on the service provider’s rates.
