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. A red light indicates when the house battery is being charged.

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.

MDP Main

The MDP main breaker is located inside the battery switch enclosure and provides protection for all DC power

to the MDP breaker panel. This is a "push to reset" breaker that is normally on all the time, when activated

by the house battery switch, unless tripped by an overload.

Windlass Main (Optional)

The windlass breaker is located inside the battery switch enclosure which is located in the stern bilge. This

breaker is normally on all the time, when activated by the house battery switch, unless tripped by an overload.

24-Hour Essential Circuits

The 24-Hour Essential Circuit breakers are lo-

cated inside the battery switch enclosure. The

stereo memory, mid bilge and aft auto bilge

breakers are always on regardless of the battery

switch settings. The mid bilge breaker protects

the forward shower sump. Make sure this breaker

is on before using the cabin shower or activating

the air conditioner. Breakers are also provided for

the forward bilge, the aft bilge and the battery

charger wiring.

BATTERY SWITCHES

There are three battery switches and two parallel switches to manage the 12-volt power distribution.

The Port Start switch controls the battery for the port engine. The Starboard Start switch controls the battery

for the starboard engine. The House switch provides power to the house circuits. The house battery is charged

by the starboard engine or the battery charger.

The Parallel switches connect the port and house batteries or the starboard engine and house batteries for
