The car's alternator does the job of keeping your battery charged and producing the energy to run the electrical accessories in your car. Signs of trouble with your alternator could be a whining noise from the engine as you speed up, or your car's battery light staying on.

Your car's battery stores electrical power needed in starting the engine. When the key is turned to the start position, electricity from the battery goes to the starter.

Your car's starter is a small electric motor that supplies energy to ignite the fuel and air mixture in the engine. The battery supplies power for the starter to operate.

Transmissions are not an electrical component! Your car has one of two types of transmissions, either manual or automatic. If your car has a manual transmission, there's an extra foot pedal on the floorboard, which operates the clutch.
