Don't let a failing alternator leave you stranded. Our certified technicians specialize in diagnosing and replacing faulty alternators, ensuring your vehicle's battery stays charged and electrical components function properly.
Transparent pricing with no hidden fees. Final cost depends on your vehicle's make, model, and alternator accessibility.
We perform thorough diagnostics to accurately identify alternator issues before recommending any repairs.
Check for obvious damage, cracks, corrosion, or loose connections. Inspect drive belt for wear and proper tension.
Verify battery condition with multimeter. Should read around 12.6 volts with engine off to establish baseline.
With engine running, measure voltage at battery terminals. Healthy alternator produces 13.8–14.8 volts.
Turn on headlights, A/C, and radio to verify alternator maintains correct voltage under electrical load.
Measure current output with ammeter. Output should match manufacturer specifications for your vehicle.
Check diodes that convert AC to DC current. Faulty diodes cause battery drain and charging issues.
Listen for grinding or whining sounds indicating bearing failure or other mechanical issues.
An alternator is a critical component responsible for generating electricity to power your vehicle's electrical systems and charge the battery while the engine is running. It converts mechanical energy from the engine into electrical energy through electromagnetic induction.
Without a properly functioning alternator, your battery will quickly drain, leaving you stranded. The alternator powers everything from your headlights and radio to your power windows and fuel injection system.
Watch for these common symptoms that indicate your alternator may be failing.
Headlights and interior lights dim or flicker because the alternator isn't providing enough power.
Dashboard battery light illuminates while driving, indicating a charging system problem.
Battery frequently dead or needs jump-starting often, even though the battery is relatively new.
Grinding or whining sounds from the alternator area, indicating worn bearings or internal damage.
Power windows, seats, radio, or other electrical components work slowly or intermittently.
Vehicle stalls because the ignition system and fuel injectors aren't receiving enough power.
Burning rubber or electrical smell indicating an overheating alternator or belt issue.
Multimeter readings outside the 13.5–14.5 volt range when engine is running.
