Help! My Headlights Are So Dim That I Can’t See at Night!

If your headlights are so dim that you can’t see at night, there’s a problem with your car, truck, or utility vehicle’s alternator or battery. In this blog post, New Castle Auto Repair is going to talk about the alternator. This is the electrical system part that generates voltage and keeps the battery charged. It also provides power to your vehicle’s accessories and some of the components. Aside from dim headlights, here are other signs that your alternator is going bad.

Accessory Malfunction

As we just mentioned, the alternator powers your vehicle’s accessories. This includes things such as your USB charging ports, the radio, and the power seats and windows. If any of these things start to malfunction, it’s possible that the alternator is unable to provide them with power.

Burning Electrical Wires

On average, the alternator generates a maximum voltage of 14.5 volts. A malfunctioning alternator may generate more voltage and overload the electrical system. When this happens, you will smell burning electrical wires and insulation coming from the engine.

Dashboard Warning Light

A dying alternator may indirectly cause a warning light to turn on on the dashboard. For example, you might see an ALT light or a GEN light. You may also see a battery-shaped light turn on to let you know that there is a problem with the alternator. The engine control unit turns on these lights.

Frequent Engine Stalling

The alternator also powers the spark plugs so they can fire to generate sparks in the combustion chamber. If your engine has started to stall frequently, it’s possible that the spark plugs are not receiving enough power from the alternator to fire correctly.

Grinding or Growling Sounds

You may also hear grinding or growling sounds coming from the engine if the alternator is malfunctioning. This is usually an indication that the alternator’s various parts have worn out. Squealing noises could be coming from the alternator belt.

Hard Starts/Dead Battery

Finally, as we mentioned above, the alternator keeps the battery charged. If it is dying, you may have difficulty starting your automobile because the battery is dead. If the battery does not maintain a charge after you have jump-started it, the alternator is no longer charging the battery.

New Castle Auto Repair in New Castle, PA, can test your alternator to see if it is no longer able to produce power. If this is the case, we will install a new alternator into your car, truck, or C/SUV.
