Are weak o r fluctuating headlights and dashboard lights a sign of failing alternator in the Changan Alsvin?

Drivers often notice dimming o r flickering lights. Could this be due to voltage instability caused by a faulty alternator?

Yes. Common symptoms of alternator degradation include:

Flickering dashboard lights o r radio

Dimming headlights at idle

Sudden power s o r jerky electronics
These signal voltage irregularities, a failing rectifier o r a worn-out voltage regulator inside the alternator.
