Keep Your Battery Charged & Electrical System Working.
The alternator recharges your vehicle's battery while the engine is running and powers many electrical systems.
When the alternator weakens or fails, your battery may drain, warning lights may appear, accessories may act strange, and the vehicle may eventually stall or fail to restart.
Georgia Fuel & Treats tests the alternator, battery, cables, terminals, serpentine belt, starter, fuses, relays, and related electrical components before recommending replacement.
What Are You Experiencing?
Select a symptom below to see common possible causes.
Alternator output, charging voltage, belt condition, battery health, or wiring may be involved.
Recommended: Charging system test.Low charging voltage, a weak battery, alternator problems, or poor electrical connections may contribute.
Recommended: Charging and battery inspection.A weak alternator, failing battery, parasitic draw, or poor cable connections may be involved.
Recommended: Battery and charging system diagnosis.Loss of charging output can eventually drain the battery and cause the vehicle to stall.
Recommended: Prompt electrical inspection.Alternator bearings, belt tensioner, pulleys, or accessory-drive components may be involved.
Recommended: Alternator and belt-drive inspection.Low voltage, charging faults, wiring issues, or battery condition may affect accessories and electronics.
Recommended: Electrical-system review.Overheated wiring, alternator stress, belt slip, or electrical failure may be involved.
Recommended: Prompt charging-system inspection.A failing alternator may not recharge the battery properly after the engine starts.

Battery Problem
Slow cranking, rapid clicking, dim lights before starting, weak accessories, or needing a jump-start may point to a weak battery or poor battery connections.
Starter Problem
A single click, no crank with a good battery, grinding noise, or intermittent no-start may point toward the starter motor, solenoid, relay, or starter circuit.
Alternator Problem
Battery light, repeated dead battery, dimming lights while driving, stalling, or low charging voltage may point to alternator or charging system failure.

Frequently Asked Questions
Common signs include the battery warning light, repeated dead batteries, dim headlights, electrical accessories malfunctioning, whining noises, burning smells, or the vehicle stalling while driving.
Yes. If the alternator cannot properly recharge the battery while the engine is running, the battery will eventually discharge and the vehicle may not restart.
Driving with a failing alternator is risky. Once the battery loses enough charge, the vehicle may stall and leave you stranded.
Charging system diagnostics generally range from $79–$149. Alternator replacement typically ranges from $450–$1,200+, depending on the vehicle and labor requirements.
