Identified Causes
Faulty Alternator
70%The alternator is responsible for recharging the battery while the engine is running. If it's failing, the battery will not receive sufficient charge, leading to the warning light.
Worn or Damaged Battery
20%An old or damaged battery may not be able to hold a charge effectively, even if the alternator is functioning correctly. This can cause the warning light to illuminate as the system voltage drops.
