Function And Common Failure Modes
The alternator converts mechanical energy from the engine into electrical power to charge the battery and power on-board electronics while the engine runs. Typical failure symptoms include dimming lights, battery discharge, dashboard warning lights (battery/charging), unusual bearing noise, or voltage instability. Common causes of failure are worn brushes, bearing wear, diode or rectifier faults, voltage regulator failure, or accessory belt slippage and contamination.
Installation Guidance
Recommended for professional installation, but doable by experienced DIY mechanics. General replacement steps:
- Disconnect the negative battery terminal to prevent short circuits.
- Relieve belt tension and remove the drive belt from the alternator pulley.
- Disconnect electrical connectors and the battery output cable from the alternator.
- Unbolt the alternator mounting bolts, remove the unit and install the replacement in reverse order.
- Check belt condition and tension, inspect wiring and battery condition before finishing.
Maintenance And Expected Service Life
Service life depends on vehicle usage and operating conditions. Under normal conditions, alternators commonly last well over 100,000 km; heavy stop-start use, short trips, or exposure to heat and contamination can shorten life. Regular inspection of the drive belt, battery health and electrical connections helps prevent premature failures.
