Why You May Need Alternator Replacement in Sioux Falls

At Team Automotive in Sioux Falls, we understand the importance of a functional alternator for your vehicle's electrical system. Here, we provide information about why you might need to replace your alternator and the services we offer to ensure your vehicle runs smoothly.

Key Reasons for Alternator Replacement:

The alternator is essential for converting engine power into electricity, powering your car's electrical systems, including lights, radio, and engine control units.

Common Causes for Alternator Replacement:
  • Worn Brushes

    Over time, alternator brushes wear out, reducing their ability to contact the slip rings and generate electricity. Symptoms include:

    • Dim headlights and interior lights
    • Difficulty starting the engine
    • Dashboard warning lights, like the battery light

  • Faulty Diodes

    The alternator's diodes convert AC to DC electricity. If diodes fail, the alternator won't generate enough electricity, causing similar symptoms to worn brushes.

  • Damaged Bearings

    The alternator's bearings allow the rotor to spin. Worn or damaged bearings can cause grinding or whining noises and can eventually seize, stopping the alternator.

  • Voltage Regulator Failure

    The voltage regulator manages electricity output. If it fails, it can cause overcharging or undercharging, damaging the battery and other components.

  • Age

    Alternators typically last 7-10 years or 100,000-150,000 miles. If your alternator is old and showing wear, it might be time for a replacement.

Indicators of a Failing Alternator:

Beyond the symptoms above, additional signs include:

  • A burning smell from the engine bay
  • Slow engine crank
  • Malfunctioning electrical components
