4 Common Auto Electrical Issues

From rolling down your windows to turning on your headlights, your car requires electricity to properly function. Vehicles have an intricate and complex electrical system, and if you notice that your car doesn’t seem to power electrical components correctly — for example, if your power seat is having trouble or your headlights are dim — it’s important to figure out what is causing the issue. Here are a few common problems that may be hindering your car’s electrical system.


Bad Spark Plugs or Wires

The spark plugs are fed an electrical charge that ignites the motor’s air and fuel mixture, creating a small explosion that powers the vehicle’s pistons. If the plugs or spark plug wires become corroded, the engine will not operate properly. A rough idle, poor acceleration, or decreased fuel economy may be signs that you need new spark plugs.

Bad Alternator

The alternator runs most electrical accessories and necessities during your car’s operation. The alternator is attached to a belt that is spun by the motion of the engine, generating electrical energy. Excess energy created by the alternator is stored in the battery in order to power accessories while the car is off and to ensure the vehicle can start. If the electrical components in your car aren’t working properly, there’s a good chance the alternator is the culprit.

Blown Fuse

One of the most common auto electrical problems is a blown fuse. If a specific accessory or electrical system stops working, such as the radio or blinker lights, you will want to check out the fuse. The fuse is what dictates how much power is sent to a particular system. If the fuse becomes overloaded somehow, it will blow, requiring a replacement. Fortunately these fuses are cheap and simple to replace.

Dead Battery

The battery stores the excess electricity produced by the alternator. It may die due to age, but often it has just been accidentally drained by unintentionally leaving on an interior light or running the radio or lights while the vehicle is off. If you turn the key in your ignition and absolutely nothing happens, chances are the battery is dead.
