The electrical starter holds the chief responsibility for carrying out the process involved in starting up vehicles. Mounted low near the back of the engine, the starter is comprised of a powerful direct current (DC) electric motor and starter solenoid, which is attached to the motor.

What are starters and how do they work

How Does it Work?

  • The starter is an electric motor that starts the engine by cranking it.
  • It's powered by the vehicle's battery.
  • To turn on the engine, the starter motor requires a high-electric current, which means the battery has to have sufficient power.
  • In most vehicles, the ignition key powers the starter switch. Turning the key beyond the ignition position allows you to feel the current that is sent to the solenoid.

How is it Made?

  • Each part is grounded to the metal car body.
  • The starter contains a wire that carries the electrical current to all necessary components.

Why Does it Fail?

  • Faulty starter motor
  • Weak or worn battery
  • Loose battery terminal connection
  • Malfunctioning solenoid
  • Loose solenoid cable connection
  • Old age and excessive use

What are the Symptoms of Failure?

  • Freewheeling
  • Grinding noise
  • Smoke
  • Malfunctioning solenoid

What are the Implications of Failure?

  • Vehicle won't start
