As the sheave most people call it a pulley is rotated by a belt connected to the automobile engines crankshaft.
Alternators produce alternating current through a process known as electromagnetism.
Once the vehicle is running pulleys on the running engine rotate a belt connected to the alternator which then causes the internal.

Alternators are mounted to the engine and are operated by a serpentine belt or powered by the crankshaft directly.

Automobile alternators perform more duties than simply recharging a cars battery.
A drive pulley is attached to the rotor shaft on the front of the alternator.
As can be seen from figure 5 a schematic for an actual alternator there is a path to ground from the field current supply input 1 to the regulator.

As a result when the key is turned on current flows through the warning lamp through the resisters transistors and field coil and then to ground.
