Without a properly-functioning alternator, you can typically drive no more than 20-30 miles without putting the rest of the electrical system of the vehicle in danger. Because the alternator is responsible for keeping the electrical components of the car powered, if it fails or is not working correctly, it can cause the battery to become quickly drained, limiting your ability to drive a long distance.
Without an alternator, your lights, radio, and other components will quickly stop functioning, leaving you stranded. Depending on a variety of factors, the amount of time you can drive your car without an alternator can vary, but 20-30 miles is a safe estimate.
It is best to get to a service station as soon as possible if your car’s alternator is not functioning properly, since driving further can cause more damage to the electrical system.
Can I drive my car if the alternator is not working?
No, it is not safe to drive your car if the alternator is not working. The alternator is responsible for generating electricity to power the electrical components of your car. Without it, you wouldn’t be able to power the ignition system or headlights, which can be dangerous to drive without.
Additionally, the alternator also produces a charge to the battery to keep it topped up, and without it your car won’t be able to start or stay running for long. As a result, it is highly recommended that you get the alternator fixed before driving your car any further, as it could cause serious damage to your vehicle.
How long can a car run with a bad alternator?
A car with a bad alternator can run temporarily, but it will eventually fail. The typical lifespan of an alternator is between 40,000 and 70,000 miles, but they can last beyond that as well. Depending on how bad the alternator is, the car may be able to run for a few days or even a few weeks, although any extra strain like using the air conditioning or headlights will cause the car to fail sooner.
Eventually, the battery will become drained, and the car will no longer start or run. Many alternator warning signs will become more noticeable as the alternator continues to fail such as dim headlights, being unable to start after sitting for a long period, decreased fuel efficiency and hearing a grinding sound when accelerating from a stop.
It is recommended to have a certified mechanic diagnose and repair the alternator as soon as possible.
What happens if your alternator goes out while driving?
If your alternator goes out while you are driving, it will become increasingly difficult to keep the engine running. Your battery will start to drain as it compensates for the power the alternator would normally be providing, and sooner or later the battery will be completely drained and your car will shut down.
In this situation, you will need to get the car towed to a mechanic in order to replace the alternator. Without a functional alternator, your car will not be able to power the electrical components in your vehicle, such as the lights, the windshield wipers, and the air conditioning, and therefore, you will be unable to continue driving until the alternator is replaced.
What kills a car alternator?
A car’s alternator can be killed by a variety of things. Most often it is a combination of factors that lead to its demise. Many times, an alternator can die from prolonged use or prolonged electrical strain, or from dirt and debris getting inside the alternator and shorting out the wiring.

Including dimming lights, slow engine cranking or trouble starting the engine, abnormal electrical or engine performance, or a burned out or blinking dash light. Dimming lights can be one of the first indications that your alternator is on its way out, as the battery is not being recharged.
Slow cranking and difficulty starting the engine occur because the alternator is no longer able to supply sufficient power to the starter or other systems. Additionally, engine performance can be affected because your alternator is no longer charging the battery and sending sufficient power to the spark plugs.
Lastly, a burned out or blinking dash light is an indication that the alternator is not able to charge the battery and power the electrical systems. If you are experiencing any of these symptoms, have your vehicle inspected to determine if your alternator needs to be serviced or replaced.
What causes an alternator to fail?
An alternator is an important component of your vehicle’s electrical system, used to power electrical components and recharge the battery. An alternator can fail due to a variety of reasons, including age, excessive heat, loose wiring, low fluid levels, and mechanical strain.
Age is an unavoidable factor that can cause alternator failure. As alternators are constantly being used, the life of the part decreases over time. This means that when the alternator starts to fail, it’s usually because it’s too worn or corroded to continue functioning.
Excessive heat generated by the alternator can also cause it to fail. The alternator is designed to create heat as it operates. If the fan that cools the alternator isn’t functioning properly, the excessive heat could cause the alternator to fail.
Loose wiring is another cause of alternator failure. Wiring that is not properly connected to the alternator can become corroded and frayed, leading to a poor connection or an open circuit. This insufficient connection can cause the alternator to not work and eventually lead to an alternator failure.
If the levels of coolant, oil and other fluids aren’t kept at the expected levels, the alternator can experience mechanical strain and eventually fail. Low levels of coolants, lubricants, and other fluids can cause parts within the alternator to overheat or not function correctly.
Alternator failure is a serious problem that should be addressed quickly. If your alternator is not working correctly, it’s important to have your vehicle inspected by a qualified technician to diagnose the cause of the problem and, if necessary, replace the alternator.
Is it worth replacing an alternator?
