Car Alternator Repair in NJ

Keep Your Battery Charged, Lights Bright & Engine Running

Your car’s alternator is responsible for powering the electrical system and keeping the battery charged while you drive. When it fails, your vehicle may lose power, stall unexpectedly, or refuse to start altogether. At Three Brothers Auto Repair Service, we provide professional alternator diagnostics and repair across NJ to keep your vehicle reliable, safe, and road-ready.

Signs Your Alternator May Be Failing

• Dim or flickering headlights while driving

• Battery warning light illuminated on the dashboard

• Electrical accessories malfunctioning (radio, windows, lights)

• Engine stalls or won’t start even with a healthy battery

• Burning rubber or electrical smell under the hood

• Whining or grinding noises from the engine area

A faulty alternator can lead to a drained battery and total loss of electrical power—early diagnosis is key to avoiding breakdowns.
