Likewise, what is field voltage in the alternator?

The alternator has a regulator that tries to keep the voltage across the battery at a steady 14.4V (the optimal voltage to recharge 12V car batteries). It does this by regulating the amount of current flowing to the field coil.

What are the parts of an alternator?

An alternator has three main components, each playing a specific role to keep the car's battery fully charged.
  • Rotor and Stator. The rotor and stator of an alternator are a belt-driven group of magnets inside copper wiring that creates a magnetic field.
  • Diode Assembly.
  • Voltage Regulator.

What is a diode in an alternator?

Bad diodes are a common cause of alternator failure. The diodes are part of the rectifier assembly that converts the alternator's AC output to DC. The alternator's charging output flows through six diodes in the rectifier assembly before it goes to the battery and electrical system.
