Several factors can contribute to alternator failure in your Suzuki Cultus:

Worn-out Brushes: The alternator has brushes that make contact with the rotor to generate electrical power. Over time, these brushes can wear out and cause the alternator to stop functioning.
Faulty Voltage Regulator: The voltage regulator controls the voltage output from the alternator. If it malfunctions, the alternator may not provide the correct amount of power to the battery o r electrical systems.
Worn Bearings: The alternator contains bearings that allow it to spin smoothly. If these bearings wear out o r seize, the alternator will not function properly.
Loose o r Broken Alternator Belt: If the belt that drives the alternator becomes loose o r breaks, the alternator won’t be able to charge the battery.
Corrosion o r Electrical Issues: Over time, corrosion can build up on the alternator’s electrical connections, preventing it from delivering power efficiently.
Solution:

Regular Maintenance: Periodically check the alternator, belt, and battery terminals for signs of wear, corrosion, o r damage.
Replace Faulty Components: If you notice any of the symptoms mentioned such as dimming lights, stalling, o r battery draining, have the alternator and related components inspected. In some cases, a simple replacement of brushes o r the voltage regulator may resolve the issue.
Keep the Belt Tight: Ensure that the alternator belt is properly tensioned and in good condition to avoid damage.
