Identified Causes

2 causes
#1

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.

#2

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.
