Charging System - Ford EXPEDITION 2005 Technical Training Manual

Charging System

Smart Charge Generator
•
The 2005 Expedition and Navigator are both equipped with a PCM-controlled charging system known as Smart
Charge. On this system, the PCM determines the optimal charging voltage setpoint. Once the PCM has
determined the optimal charging voltage for a given situation, the PCM signals the voltage regulator to control
generator output. This system operates similar to the charging system used on the Crown Victoria/Grand
Marquis/Town Car. For diagnosis and repair information, refer to the appropriate section of the Workshop
Manual.
