In many cases, a bad alternator will not prevent a car from starting. However, a car’s electrical system relies on the alternator to keep the battery charged, so a bad alternator can cause problems with the car’s electrical system and headlights. If the alternator is not working properly, the battery will eventually die, and the car will not be able to start.

How do you tell if its your alternator or your battery?
How do you know if it is your alternator or battery that is not working?
One way to tell if you alternator is not working is if the car will not start. Another sign that your alternator is not working is if the car is making a whining noise. If the battery is not holding a charge, it might be time to get a new one. One way to tell if your battery is not holding a charge is if the car headlights get dim when the car is started.
What are the symptoms of a bad alternator?
If you’re experiencing any of the following symptoms, you may have a bad alternator:
-Your car battery is dying or has died completely
-You’re experiencing dimming headlights or other electrical problems
-The car’s charging system warning light is on
-You’re hearing a strange noise coming from the alternator
-The car is not accelerating as quickly as it used to
If you’re experiencing any of these symptoms, it’s best to have your car’s charging system checked out by a professional.
Why won’t my car start but I have power?
There are a few things that could be causing your car not to start, even though you have power. One possibility is that the battery is dead. If the battery is more than three years old, it may not have enough power to start the car. Another possibility is that the starter is faulty and needs to be replaced. If neither of these things are the problem, it may be that there is a problem with the ignition. In this case, you may need to have the ignition system repaired or replaced.
When your car won’t start but all the lights come on?
If your car won’t start, but all the lights come on, it’s likely that you have a problem with your battery. The battery is responsible for supplying power to your car’s ignition system, so if it’s not working properly, your car won’t start.
There are a few things you can do to troubleshoot a battery problem. First, make sure that the battery is properly connected to the car. If the battery terminals are corroded, they may not be making a good connection, which could cause the car not to start.
You can also test the battery to see if it’s still charging. To do this, use a voltmeter to measure the battery’s voltage. If the voltage is below 12.4 volts, the battery is not charging and may need to be replaced.
If you’ve determined that the battery is not the problem, there may be a problem with the starter or the ignition system. In these cases, it’s best to take the car to a mechanic to have it diagnosed.
How long will a car run with a bad alternator?
How long can a car run with a bad alternator? This is a question that many drivers ask, and the answer is not always straightforward. In general, a car can run for quite some time with a bad alternator – but how long depends on a variety of factors.
One of the most important things to consider is how much alternator current the car is using. If the alternator is not providing enough current to meet the car’s needs, the battery will start to discharge. Once the battery is discharged, the car will not be able to run.
Another important factor is the type of alternator. A car with an older, belt-driven alternator can run for a longer time than a car with a newer, serpentine-belt-driven alternator. This is because the belt-driven alternator has more moving parts, which means it is more likely to wear out.
In general, a car with a bad alternator can run for a few hundred miles, or a few days, depending on the factors mentioned above. If you think your car has a bad alternator, it is best to have it checked out by a mechanic.
What happens when the alternator goes out?
An alternator is an electric generator that converts mechanical energy to electrical energy. It does this by using a rotating armature to generate an electrical current in a stationary field winding.
The alternator is a key component of the electrical system in a car. It generates power for the car’s electrical system, including the starter motor, the lights, and the ignition system.
If the alternator goes out, the car will not be able to run. The battery will provide power for a short time, but eventually it will run down and the car will stop.
Why would a car not start if the battery and alternator are good?
There are a few reasons why a car might not start if the battery and alternator are both good. One reason could be a bad starter. Another reason could be a bad alternator. A bad ground connection could also be the culprit.
