Charging System: Generator(s)
WARNING: This page is about a different car, the 2009 Ford RV Cutaway, 2009 Ford Econoline, 2009 Ford E450 Super Duty, and 2009 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The charging system is a negative ground system. The generator is belt-driven by the engine accessory drive system. When the engine is started, the generator begins to generate AC current, which is internally converted to DC. This current is then supplied to the vehicle electrical system through the output (B+) terminal of the generator.
