Alternators fail due to wear and tear o r external damage. Common causes include:

Worn-Out Bearings – Causes whining o r grinding noises before complete failure.
Voltage Regulator Malfunction – Leads to overcharging o r undercharging the battery.
Worn Carbon Brushes – Prevents proper electrical contact inside the alternator.
Corroded o r Loose Wiring – Poor connections can cause inconsistent charging.
Overheating – High engine temperatures can damage internal components.
Water o r Mud Exposure – Driving through deep water can short-circuit the alternator.

Regular inspections can help detect early issues.
