    Alternator Repair

    When you bring your car in for an alternator repair, skilled technicians will carefully assess various components to identify the root cause of the problem. The alternator itself will be thoroughly inspected for any signs of damage, wear, or mechanical issues. This includes checking the housing, bearings, and connections to ensure everything is in proper working condition.

    Alternator Replacement

    Along with replacing the alternator, a thorough inspection of related components should be performed. This may include checking the battery, belts, pulleys, and other parts of the charging system such as the voltage regulator to ensure they are in good condition and functioning properly.

    Alternator Testing

    • Visual Inspection: Begin with a visual inspection of the alternator and its connections. Look for any visible signs of damage, such as frayed wires, loose connections, or physical wear.
    • Battery Voltage Test: Use a multimeter to measure the voltage across the battery terminals with the engine off. A healthy battery typically reads around 12.6 volts or higher. A significantly lower voltage may indicate a problem with the alternator’s charging function.
    • Battery Load Test: Perform a load test on the battery to check its overall health and capacity. This test helps determine if the battery is holding a charge properly and if it can handle the electrical load of the vehicle.
    • Alternator Output Test: Start the engine and measure the voltage across the battery terminals while it is running. A properly functioning alternator should produce a voltage between 13.8 and 14.8 volts, indicating that it is charging the battery.
    • Alternator Diode Test: Test the diodes within the alternator to ensure they are functioning correctly. Faulty diodes can cause issues with the charging system. A diode test will check for any abnormal voltage readings in both directions.
    • Alternator Load Test: Use a specialized alternator load tester to put a load on the alternator and simulate real-world conditions. This test helps evaluate the alternator’s performance under a significant electrical load.
    • Belt Tension Test: Check the tension and condition of the alternator belt. A loose or worn-out belt can affect the alternator’s performance and should be adjusted or replaced if necessary.

    My 1997 Camaro fuel pump went out in a parking lot. Had it towed to H&I. The fuel pump was replaced by them to years ago. They stood behind their warranty and replaced it at no charge. They recommended additional service for the fuel system since I rarely drive the car that much I even saw the owner working on my car with the technicians. When a business stands behind their work, it means a lot to a customer. I don’t mind driving the extra distance to get to their shop. As long as I can get my vehicle to them, they will continue to do my work.
