CFII-1224Centerfielder II: CFII-12/24
Balanced Twin Engine Charging

  • Balances Charging in Twin Engine Applications
  • Eliminates Alternator Chatter by Unifying Field Current
  • For Use with Max Charge Regulators Only
  • Works in Both 12V and 24V Applications
  • Includes Upgraded Regulator Power Wires and Fusing
  • Isolates Alternators and Regulators when only One Engine is Running
  • Can be Used with the Digital Duo Charge to charge a Second Battery

The Centerfielder II (CFII-12/24) balances twin engine charging systems by monitoring the port and starboard voltage regulators. When both alternators and regulators are working, the Centerfielder II automatically designates the starboard regulator as dominant for both alternators – making it possible to charge a single house battery bank with the combined output of both alternators. The Centerfielder II eliminates the “yo-yo effect” of two regulators repeatedly turning on and off as the battery approaches target voltage because the two systems are not working in concert.

Typical Centerfielder II System Wiring Diagram

Useful in applications like multihulls and powerboats with twin propulsion motors, the Centerfielder II acts like a referee, ensuring that both port and starboard charging systems work together, rather than compete, to keep a large house battery efficiently charged. The Centerfielder II is designed to work specifically with MC-614 and MC-624 voltage regulators.Centerfielder Diagram
