What Causes the Dashboard to Flicker?
1 Answers
Dashboard flickering in a car is caused by a weak car battery. Possible reasons include loose battery terminals or issues with other electrical circuits in the vehicle, which require prompt inspection. Methods to determine if a car battery needs replacement: Check battery appearance: Look for obvious signs of swelling, deformation, or bulging. Also, inspect for white or green powdery substances around the battery terminals and sides. These substances are battery oxides. High-quality or new batteries are less prone to oxidation. If oxides are present, it indicates battery performance issues, and replacement is necessary. Check the battery's observation window: Some maintenance-free batteries have a charge indicator window, typically displaying three colors: green, yellow, and black. Green indicates sufficient charge, yellow means slightly weak, and black signifies near failure, requiring replacement. Measure battery voltage: Use a battery tester or multimeter to measure the battery voltage and determine if the car battery needs replacement.
