Common Car Electrical Problems

Your vehicle's electrical components are vital to the drivability of your car. You need your lights to be able to see in the dark and view your dashboard. You also need your power locks and windows to lock your car and put down your windows for fresh air. Most importantly, you need your vehicle's battery and surrounding charging systems to work in harmony together to power your vehicle. So when an electrical problem occurs, it is important to have it addressed and taken care of as soon as possible. 

The main parts of the electrical system are the battery, alternator, and the starter. The battery is the component that provides the electrical current to start up your vehicle. The starter will use a small amount of power from the battery to rotate the flywheel which will turn the crankshaft, moving the engine pistons. The alternator is important once your vehicle is running, because it recycles energy to keep the battery charged and the electrical system working.

The following are some common car electrical problems that can occur: 

  • A dead or dying battery, which can prevent your car from starting completely. You may see the battery warning light appear on your dashboard if your battery is lacking in charge. 
  • Corroded battery cables can prevent the correct current from passing from the battery to the electrical components. 
  • A faulty alternator can cause problems when it comes to recycling energy and keeping your battery charge. A car that starts but won't stay running is typically a sign of a bad alternator. 
  • A broken serpentine belt will stop the alternator from running, which can cause your vehicle to shut off unexpectedly. 
  • A blown fuse can also be the cause of a malfunctioning electrical component, such as the power windows. 
  • Wiring problems can also cause electrical components to fail, typically individually.
