The alternator is your vehicle's electrical generator, converting mechanical energy from the engine into electrical power to charge the battery and run all electrical systems while driving. When the alternator fails, your battery will drain, electrical systems will malfunction, and eventually your vehicle won't start or run.
Signs of Failure
- Dim or flickering headlights
- Battery warning light on dashboard
- Dead battery or won't hold charge
- Electrical accessories malfunctioning
- Whining or grinding noise from engine
- Burning rubber smell
- Stalling or difficulty starting
- Dashboard lights dimming at idle
Replacement Info
Alternator replacement is a moderate DIY job accessible to most home mechanics. The alternator is typically mounted on the front of the engine, driven by the serpentine belt. Replacement involves: disconnecting the battery, removing the belt tensioner to release belt tension, disconnecting electrical connections, unbolting the alternator, and reversing the process with the new unit. Most replacements take 1-2 hours. Some vehicles have alternators in difficult locations requiring additional component removal.
Time: 1-3 hours
Difficulty: Moderate DIY

OEM vs Aftermarket — 2021 Aston-Martin Dbx Alternator
Recommendation: Quality Aftermarket or Used OEM
Alternators are highly standardized components where quality aftermarket units perform comparably to OEM. Remanufactured alternators from reputable brands offer excellent value with new bearings, brushes, and regulators. Used OEM alternators are also reliable if from low-mileage donors. The key is buying from quality suppliers - avoid the cheapest options which may use inferior bearings or voltage regulators that fail prematurely.
OEM Advantages
- Exact fit and output specifications
- OE quality bearings and components
- Known reliability record
- Proper pulley size and type
- Correct connector configuration
Aftermarket Advantages
- Often includes lifetime warranty
- New bearings and brushes
- May include updated designs
- Competitive pricing
