Common Failure Modes & Maintenance
Alternators commonly fail due to worn bearings, brush and slip-ring wear, voltage regulator malfunction, diode pack failure or contamination from oil and coolant leaks. Belt slip or damaged pulleys can also reduce charging performance. Lifespan depends on vehicle use and environment; many alternators last well over 100,000 km, but heavy stop-start operation, charging loads or exposure to contaminants can shorten service life. Regular visual inspection, pulley alignment checks and ensuring clean electrical connections improve reliability.
