Alternator Repair in Keene, NH – Keep Your Car Charged and Running Right

Your vehicle’s alternator is a key component of its charging system, working alongside the battery and voltage regulator to power all electronic functions—from headlights and air conditioning to your dashboard and infotainment systems. If your alternator isn’t working properly, your car could lose power unexpectedly or fail to start altogether.

At Leon's Auto Center in Keene, Cheshire County, our certified technicians specialize in alternator diagnostics and repair services for all makes and models, including Chevrolet, Dodge, Honda, Jeep, and more.

What Does an Alternator Do?

The alternator converts mechanical energy into electrical energy using alternating current (AC). It’s typically mounted at the front of the engine and driven by the crankshaft via the serpentine belt. It recharges the battery and powers all of your car’s electronic systems while the engine is running.

Key functions include:

  • Generating electrical power to run systems like the radio, lights, and A/C

  • Charging the battery while you drive

  • Regulating voltage output to prevent overcharging

The alternator has several terminals and a voltage regulator that work together to keep everything running smoothly. A failure in any part of this system can lead to power loss and reduced vehicle performance.

Signs You Need Alternator Repair

If your alternator is malfunctioning, your car will give you clear signs. Watch out for the following symptoms and bring your vehicle to Leon's Auto Center in Keene, NH right away:

  • Battery light is on: A glowing or flashing battery, ALT, or GEN light on your dashboard may indicate a charging issue.

  • Dimming headlights or slow electronics: If your lights flicker or your windows roll slowly, your alternator may not be producing enough power.

  • Loose serpentine belt: This belt powers the alternator, and if it becomes loose or worn, it can hinder performance.

  • Unusual noises: Grinding or whining sounds from the engine bay can point to worn alternator bearings or internal components.

  • Malfunctioning accessories: A weak alternator can cause your radio, GPS, or backup camera to behave erratically.
