What are the functions of a starter?

A car starter is a little motor of its own. Both starters and solenoids are part of the vehicle starting system. Their role is to start the engine. It does so by engaging the flywheel and turning the gear, thus making the engine start as soon as the driver turns his keys to the right position. This action is made possible by the starter’s solenoid. The solenoid is an electric relay that sends the power from the battery to the starter. The battery must have sufficient capacity of energy to start the whole process.

Though simple, it requires precise electrical components so the starter is able to operate in hot summer or on a winter morning for many years to come.

What are the functions of an alternator?

Your car’s electrical system is an essential part of your vehicle power train. It’s simple, without an alternator, the battery would not be able to provide the energy needed by a vehicle. An alternator converts mechanical energy into electrical energy so that the electrical components of a vehicle can reach power. If you add the other parts, cables and sensors required by your car’s electrical system, any failure will make your car run poorly, with the risk of being stranded on the side of the road.

In addition, if you are driving a hybrid car or a vehicle with an idle stop-start option, your alternator acts as a starter for your car’s powertrain.
