A failing alternator in your Suzuki Cultus may present several symptoms. Some of the most common signs of alternator failure include:

Dimming o r Flickering Lights: When the alternator is not generating enough power, the headlights and interior lights may become dim o r flicker.
Battery Warning Light: Most vehicles have a battery-shaped warning light on the dashboard. If the alternator is failing, this light may turn on, indicating a charging issue.
Difficulty Starting the Car: If the alternator is not charging the battery, you may experience trouble starting the car. The car may take longer to start o r fail to start completely.
Electrical Issues: Malfunctioning alternators can cause the car’s electrical systems, such as the radio o r air conditioning, to work intermittently o r not at all.
Strange Noises: A failing alternator bearing can produce a whining o r grinding noise as the alternator’s internal components begin to wear out.
Solution:

Diagnose with a Multimeter: You can check the voltage output of the alternator using a multimeter. The alternator should produce around 13.5 to 14.5 volts with the engine running.
Visit a Mechanic: If youre noticing any of these symptoms, its best to take your vehicle to a professional to check the alternator and have it replaced if necessary.
