Your car's electrical system consists of the battery, starter, and alternator. The three parts collectively work to power your vehicle and its electrical components (radio, interior/exterior lights, power seats, etc.). If one of these parts is not working correctly, you're out of luck. Your car won't start or run. Here is some more information regarding the three essential parts of your electrical system:


Battery: The battery powers all your vehicle's electrical components. The battery provides the current required to start the engine and engage the fuel system.


Starter: Though the battery supplies power to the engine, the starter triggers the engine pistons to start working. Currents flow from the battery to the starter to move the crankshaft that starts the piston.


Alternator: The alternator recharges the battery every time your car is on. This piece ensures you get a sufficient power supply to the peripheral components of your vehicle. 


Signs that You Have Auto Electrical Issues


Electrical issues for your car should not be taken lightly. Most vehicles nowadays are much more dependent on their electrical systems than before. If the alternator, battery, or starter begin to fail, drivers often experience a wide range of issues. Upon discovering these signs, you should take your vehicle into an auto shop as soon as possible. The symptoms of a failing electrical system include:


  • The engine not cranking or starting properly
  • You have corroded battery cables
  • Flickering or dimming exterior and interiors lights
  • Frequent fuse trips or blow-outs
  • The smell of burning plastic or electrical components
  • The battery warning light lights up on the dashboard
