CENTERFIELDER IICenterfielder IIThe Centerfielder balances twin enginecharging systems by monitoring portand starboard voltage regulators.When both alternators and voltageregulators are working, theCenterfielder II automatically splits fieldoutput from the dominant regulator toboth alternators, making it possible tocharge a single house battery bankwith the combined output of bothalternators.The Centerfielder II worksin both 12-volt and 24-volt applications,and includes detailed wiring instructions along with larger gauge wire replacements for port and starboardregulator power wires. Use only with Max Charge MC-612, MC-614, or MC-624 voltage regulators. Do notinstall in systems utilizing internally regulated alternators. 1 year limited warranty.• Balances charging in twin engine applications• Isolates alternators and regulators when only one engine isrunning• Provides field current from a single regulator to both port andstarboard alternators when both engines are in operation• Eliminates alternator “chatter” by unifying power output to asingle battery bank• For use with Max Charge regulators only• Includes upgraded regulator power wires and fusing for port andstarboard voltage regulator wiring harnessesModel Volts Use With Fusing Wiring Included ShWtCFII-12/24 12/24 MC-612, MC-614, MC-624 15A ATC Fused 12 Ga.
