4.3 DC Distribution System
The battery switches are a part of an integrated DC power distribution system that contains several components.
The following are descriptions of the components:
COMPONENT DESCRIPTION
Battery Switch (3): These switches feed the engine(s) and DC circuits. These are "ON/OFF" switches. Turn
the switch so that the green "ON" indicator is displayed. All three switches should be in the "ON" position
whenever the boat is in operation.
Parallel Switch: Connects the two batteries together for engine starting or charging of both batteries. This
switch should only be used for emergency starting.
Voltage Sensitive Relay (VSR): The VSR allows two batteries to be charged either by one engine or by the
on-board battery charger. The VSR prevents both batteries from being discharged by automatically isolating
the engine battery.
24-Hour Essential Circuits: Used for protection of circuits that are not switched off by battery master
switches.
Medium Duty Circuit Breaker: Used to protect high amperage circuits and panel feeds.
Heavy Duty Circuit Breaker: Used to protect the windlass circuit.
