Textbook Problem

Voltage regulation by a PCM is done by.

  1. using a variable resistor to vary' current flow to the rotor field windings

  • pulsing current flow to the rotor field windings on and off to create a correct average field current supply
  • changing the duty cycle of a current sensor to control the fields path to ground
  • none of the above
  • To determine

    The correct option for the given blank.

    Explanation

    Most of the charging system is inspected using the PCM controlled system. The scan tool is an electronic device used to diagnose the faults in the charging system.

    Generally, late-model vehicles use the PCM controlled system for batteries charge control. In this system, the generator is controlled using the PCM by controlling the duty cycle of the field current...
