Understanding and Diagnosing Ford Smart Charging System

Gm has had a "smart charging system" since the early 2000's. They call it RVC for regulated voltage control. When it 1st came out people where not used to the car volt meters saying 12.x under certain conditions when they expect to always see 14.x. These systems are good for extending battery life and for fuel economy. It adds a small amount of additional charging diagnostics but the feature is good to have.

I know my Honda CRV has a similar charging system, it is just nice to know how the work!
