Yes, a failing alternator can cause your battery to drain. The alternator is responsible for charging the battery while the engine is running, so if it’s malfunctioning, it wont charge the battery properly. This can result in the battery losing charge and eventually dying. Common signs of a failing alternator include:
Battery Warning Light: If the alternator is not charging properly, you may see the battery light illuminated on the dashboard.
Dimming o r Flickering Lights: If your headlights o r dashboard lights flicker o r dim, this could indicate that the alternator is not providing consistent power.
Electrical Issues: Other electrical systems, such as the radio, air conditioning, and power windows, may start malfunctioning.
Solution:
To confirm whether the alternator is the issue, you can use a multimeter to check the voltage at the battery. If the voltage is lower than 12.6 volts when the engine is running, it may indicate a problem with the alternator.
