Alternator Repair & Replacement at Exhaust Masters

The alternator is responsible for keeping your vehicle's battery charged and powering the electrical systems while the engine is running. When it starts to fail, the effects show up quickly across multiple systems at once. Exhaust Masters has been diagnosing and repairing alternators for Merrillville, Crown Point, Schererville, and Lake County drivers since 1974. Our ASE-certified mechanics handle alternator repair and replacement on all makes and models, domestic and foreign, including cars, trucks, SUVs, and hybrids.


When you bring your vehicle in with electrical concerns, we diagnose the full charging system before recommending a repair. In many cases, what presents as a dead battery is actually an alternator that is no longer charging properly, and replacing the battery without addressing the alternator means the new battery will fail in short order.

Signs Your Alternator Is Failing

Alternator problems tend to develop gradually before causing a complete failure. Catching the warning signs early gives you more options and prevents getting stranded. Common symptoms include:


  • Dimming or flickering headlights and interior lights
  • A battery warning light on the dashboard
  • Frequent dead battery or a battery that will not hold a charge
  • Electrical accessories behaving erratically or losing power
  • A whining or grinding noise from the engine bay
  • The smell of burning rubber or hot wiring
  • Engine stalling or difficulty starting


If your vehicle is showing any of these signs, bring it in for a charging system test before the situation leaves you stranded.

Alternator Diagnostics & Electrical System Testing


Diagnosing an alternator problem correctly requires testing the full charging system, not just the alternator in isolation. Exhaust Masters uses the latest diagnostic technology to test alternator output, check the voltage regulator, inspect wiring and connections, and assess the condition of the battery as part of the same process. This approach gives us a complete picture of the electrical system so we can identify whether the alternator is the primary problem or whether additional issues are contributing to the symptoms.


Our team explains the findings clearly and gives you an honest recommendation on whether repair or replacement is the right call for your specific vehicle and situation.

Battery & Starter Service


Alternator problems rarely exist in isolation. A failing alternator puts excessive strain on the battery, and a weak battery can mask alternator issues during testing. Exhaust Masters performs battery testing and replacement alongside alternator work to make sure the full charging system is functioning correctly once the repair is complete. Starter problems also frequently present alongside electrical system failures, and our team handles starter repair and replacement as part of the same comprehensive electrical service offering.
