Causes of a Flashing Car Battery Light When Accelerating
The flashing car battery light is often a sign of a problem with the vehicle’s electrical system. When the engine is accelerating, the battery is under increased stress, and a faulty battery can cause the light to flash. Some common causes of a flashing car battery light when accelerating include:
Loose or Corroded Battery Terminals
One of the most common causes of a flashing car battery light is loose or corroded battery terminals. When the terminals are loose or corroded, it can cause a poor connection between the battery and the electrical system, leading to a range of issues, including a flashing battery light.
Loose terminals can be caused by a variety of factors, including:
- Worn-out terminals
- Loose terminal screws
- Corrosion on the terminals
Corroded terminals can be caused by exposure to moisture, dirt, or other contaminants. To check for loose or corroded terminals, follow these steps:
- Locate the battery terminals and inspect them for signs of corrosion or wear
- Check the terminal screws to ensure they are tightened securely
- Use a wire brush to clean the terminals and remove any corrosion
- Apply a small amount of petroleum jelly or silicone-based lubricant to the terminals to prevent corrosion
Alternator Failure
The alternator is responsible for charging the battery while the engine is running. A faulty alternator can cause the battery light to flash, especially when accelerating. Some common signs of alternator failure include:
- Dim or flickering headlights
- Slow engine crank
- Dead battery
