2. The electrical system of your car is very important because it not only starts the car but also provides power to many other important parts of your vehicle.

3. The basic components of the electrical system are the battery, starter and alternator and the battery provides the entire electrical current to the vehicle before the vehicle is started.

4. Once the vehicle is running, the alternator takes over and keeps the battery charged and the electrical system working.

5. However, at times the electrical system of the car malfunctions and affects the reliability of the car. Here are the reasons behind it.

7. If the vehicle does not start or even try to turn over, then the problem lies with the battery of the car.

8. Most cars are equipped with a battery warning light that will illuminate if there is an issue with the battery or one of the other electrical system components.

9. In most of the cases a drained battery is due to the lights being left on and over time batteries will go bad and need to be replaced.

11. The battery cables are responsible for transferring the current from the battery to the electrical components of the vehicle.

12. If the car fails to start, then it will make a clicking sound or the radio and other electrical components will not work which indicates the cables could be the problem.

13. Corrosion can corrode the cable and the battery terminals and in most of the cases battery cables cannot be repaired and need to be replaced.

15. The alternator converts the power the crankshaft is generating into electrical energy which in turn charges the battery.

16. If the alternator is not able to produce enough voltage, then the battery can go dead and in most of the cases a failing alternator will trigger the Battery light.

17. Moreover, if the alternator completely fails, then the car will eventually stop running as the battery is not being recharged.

19. The voltage regulator is connected to the alternator and it controls the amount of voltage the alternator sends to the battery.

20. If this component is malfunctioning, then the alternator will not send the correct voltage to the battery which will lead to severe issues.

21. Signs of a failing voltage regulator include the battery light illuminating, dim lights, dashboard lights that dim or flicker and the engine will hesitate.

23. The electrical systems also play a major role in the functioning of the safety systems of your car like the headlight and the brake lights.

24. Whenever you come across any of these symptoms, then take your car to an automotive repair shop to fix the issue.
