[QUOTE="FordTechOne, post: 1568179, member: 35543"] Ford has been using smart charge since the early 2000’s. It uses 2 circuits to communicate with the generator (alternator) regulator; GENCOM and GENMON. Through those circuits, the PCM controls and monitors the charging voltage. Newer vehicles like the Gen 2 Raptor are more complex. In addition to Smart Charge, they use a generator current sensor and a battery monitoring sensor to determine the charging system strategy and monitor battery state of charge. The battery state of charge is part of the auto start/stop strategy. The dual battery option on Super Duty just has the second battery wired in parallel; it appears the battery monitoring sensor only reads the primary battery. However, they don’t use a generator current sensor. I suppose you could try wiring a secondary battery in parallel and see how the system functions. [/QUOTE]
