A Volkswagen starter is the indispensable electrical motor of the vehicle's electronic system which acts like switch that activates the whole machine for full operation. This auto part depends on the power charged in the battery. Significantly, if the alternator is the component that converts mechanical energy into electricity, the starter is its counterpart. It converts electricity into mechanical energy by turning the crankshaft on in order for the pistons to work. But unlike the alternator, it only uses the electric charge to trigger the mechanical energy of the engine.
The starter triggers the ignition switch to release a small amount of electricity from the battery towards the solenoid that's above the starter. This reaction creates a magnetic field which subsequently drives the solenoid plunger forward. Then, the attached shift yoke will move the starter drive so that the pinion gear connects to the engine's crankshaft flywheel. After that, the plunger would complete its travels and strike a contact to be able to let greater amount of current flow from the battery to the starter. This will make the motor spin the drive and turn the meshed gears, so to create enough energy to power the crankshaft and fully prepare the cylinders for ignition. Upon activation, the engine will start running, and would automatically break the starting circuit.
Modern Volkswagens these days may start up by the use of remote controls. Even if the driver is still trying to finish something inside the house, he can make the engine hot right before he hits the road without getting out. The sophistication of starting system may seem overwhelming, but basically the concept and components for start up process is the same as with those Volkswagens that are key-operated. And if the starter is out of order, the cause is usually just the same. And the ways of taking good care of them are basically the same.
