12 Volt Electrical System

The 12V electrical system has two house battery banks, one starting bank, and one windlass / bow thruster bank.  The starting bank is located under the navigation station seat, the house banks are located below the aft saloon floorboard outboard panels.  The windlass / bow thruster bank is located forward under the v birth.

These batteries are charged by two alternators on the engine and two 120V a/c chargers.  The house bank is charged by a Heart Freedom charger / inverter controlled by a Link 2000 control unit.  The charger / inverter is located behind the port settee in the aft compartment.  The link 2000 controller is located at the navigation station.

The windlass / bow thruster and starting banks are charged by a ProCharge 40 charger located under the navigation station desk.  This charger is setup to charge two banks one being each of these banks.  The charger is fully automatic with a display located on the inboard edge of the navigation station desk.

Two alternators are installed on the main engine these charge the two banks.  Each alternator charges an individual battery via an isolator installed behind the navigation station.  Both of these alternators are controlled via a Balmar Pro Charge controller.  These regulate the charge into a charge, accept, and float voltage during times of extended engine use.
