Your vehicle’s alternator plays a crucial role in keeping your car running by generating electrical power and charging the battery while the engine is running. If the alternator fails, your car may experience a range of electrical issues or even stop working altogether. Recognizing the signs of alternator trouble early can help you avoid getting stranded. At Hye-Tech Auto, we provide expert alternator replacement and auto electric repair in the greater Covina area. Here are five signs of alternator trouble. Dim or Flickering Lights One of the most noticeable signs of alternator trouble is dim or flickering headlights and interior lights. Since the alternator powers your car’s electrical system, when it starts to fail, the power supply becomes inconsistent. This can cause your lights to appear weaker or to flicker. Warning Light on the Dashboard Many vehicles are equipped with a dashboard warning light that illuminates when there’s a problem with the alternator. This light usually appears as a battery icon, but it may also say ALT or GEN. If this light comes on, it’s a sign that your alternator isn’t generating enough electricity, and you should have it inspected as soon as possible. Electrical Malfunctions A malfunctioning alternator can cause a variety of electrical problems in your vehicle. You might notice that power windows, door locks, or your car’s radio aren’t functioning properly. These issues occur because the alternator isn’t providing enough power to run all the electrical systems in your car. Dead Battery A dead or frequently dying battery can sometimes indicate a problem with the alternator rather than the battery itself. If the alternator isn’t charging the battery properly while you drive, the battery will eventually lose its charge and won’t be able to start the car. If you find yourself needing to jump-start your vehicle often, it could mean that your alternator is not functioning properly and is failing to recharge the battery. Strange Noises A failing alternator may produce unusual noises, such as grinding or whining sounds. These noises can result from worn bearings or belt issues. If you hear these sounds coming from under the hood, it’s a good idea to have your vehicle inspected.

The check engine light is one of the most dreaded alerts for drivers. However, it can turn on for a variety of reasons, some of which are relatively minor. The important thing is that you promptly visit the shop for diagnostics so the issue can be identified and resolved before it escalates. At Hye-Tech Auto, we provide expert check engine light repair in the greater Covina, CA area. Here are five common check engine light triggers. Faulty Oxygen Sensor Oxygen sensors monitor the amount of unburned oxygen in the exhaust system. When this sensor goes bad, it can lead to reduced fuel-efficiency and even cause issues with the catalytic converter. Ignoring a faulty oxygen sensor can result in more costly repairs, so it’s important to address this issue as soon as possible. Malfunctioning Catalytic Converter The catalytic converter plays a critical role in reducing harmful emissions from your vehicle. If this component fails, not only will your car pollute more, but you may also experience decreased engine performance. A malfunctioning catalytic converter often leads to a flashing check engine light. Faulty Mass Airflow Sensor The mass airflow (MAF) sensor measures how much air is entering the engine and helps your car’s computer determine the correct fuel-to-air ratio. If the MAF sensor malfunctions, it can cause poor fuel-economy, rough idling, or even stalling. Replacing this sensor is usually straightforward, but ignoring the problem can lead to engine performance issues. Loose or Faulty Gas Cap One of the simplest reasons the check engine light turns on is a loose or damaged gas cap. When it doesn’t form a proper seal, it can cause fuel vapors to escape, triggering the check engine light. Fortunately, tightening the cap or replacing it is an easy fix. Worn Out Spark Plugs or Ignition Coils Your car’s spark plugs and ignition coils are responsible for igniting the air-fuel mixture in the engine. As they age, these components wear out and can cause misfires, which will trigger the check engine light. Replacing spark plugs or ignition coils is relatively affordable and can prevent more serious engine problems in the future.
