Why is my battery light on with new alternator and battery?
The cause of the battery light could be a loose or corroded battery cable or other wire connecting components of the charging system, or it might be a problem with the alternator or voltage regulator. The alternator generates the power that is stored in the battery.
What does it mean when the battery light stays on?
battery charging problem
Basically, the light indicates a battery charging problem. If the light comes on and stays on while driving, this means that your alternator is running solely on energy stored in the battery. If you continue driving, your battery will eventually drain and your vehicle will stop working.
Is there a fuse between alternator and battery?
Most of the time, there’s a high-amperage fuse or fusible link between the alternator’s battery terminal and the battery. Also, there are usually low-amperage fuses in series with the alternator’s sense terminal and ignition terminal. Like any fuse, the primary alternator fuse acts as a circuit protection device.
Does battery light need to be reset?
A: After a battery is replaced in some vehicles, the battery charging system monitoring system will need to be reset. I did a bit of research and found a battery reset is required to resolve the issue. The message can reset by itself, but the car needs to sit undisturbed for at least eight hours.
Is there a fuse for a alternator?
The primary alternator fuse (or fusible link) will blow whenever there’s excessive current flow due to a short circuit or other malfunction. An example of a primary alternator fuse. As you might know, the alternator charges the battery and supplies electricity to the vehicle whenever the engine is running.
Why does my alternator light stay on?
When the light stays on, it indicates that the computer has detected an issue with the charging system. An alternator that is on its way out may cause this warning light to flash when there is a high demand on the battery.
How long does it take for battery light to reset?
The message can reset by itself, but the car needs to sit undisturbed for at least eight hours. Perhaps with your work/driving schedule the car doesn’t sit long enough.
Is there a fuse or relay for the alternator?
The alternator is driven off the engine by a belt, which allows the alternator to convert mechanical energy into electrical energy through magnetic induction. Most of the time, there’s a high-amperage fuse or fusible link between the alternator’s battery terminal and the battery.
Is there a fuse between the alternator and battery?
How do you know if your battery or alternator is bad?
If the battery is working, it’s time to take a closer look at the alternator. There are certain signs of a bad alternator to look for: While running the car, take note of the interior lights and how bright these appear. If the dashboard gradually dims, that likely means the alternator is at fault.
What are the signs of a bad alternator?
The symptoms of a bad alternator include strange noises, similar to a grinding or whining noise and an illuminated warning light. Other less noticeable and less common symptoms include weird sounds and bad smells. A burning rubber smell becomes noticeable when the alternator is going bad because the alternator works with the belt system.
Why does my car battery light stay on?
If the battery light comes on and stays on while you are driving, the most common cause is a broken alternator belt. Total failure of the alternator is another possibility. The reason why your car can operate normally even though the battery light is on is because your car can run off the energy stored in the battery.
How to test an alternator?
Collect your tools. You will need something to read the voltage/amperage of your battery and alternator.
