Electrical System
next to the holding tank monitor. It is a mo-
mentary switch that activates the level indicator
lights and the macerator discharge system for the
holding tank. Refer to the Marine Head System
in the Interior Equipment chapter for additional
information on the operation of the overboard
macerator discharge system.
Engine Trim and Tilt Switches
Located in the helm. These switches are usually
installed in the engine control handles or on the
helm console. They control the trimming and
tilting of the outdrives. Please refer to the Helm
Control Systems chapter and the engine owner’s
manual for information regarding the proper use
of the tilt and trim switches.
Automatic Fire Extinguisher Indicator Panel
and Override Switch
The panel is equipped with lights that indicate the
status of the automatic fire extinguishing system.
The green light indicates the system is charged
and ready. The red light indicates the system has
discharged.
The system is completely automatic and will shut
down the engines when it is activated. The panel
is equipped with an override switch that enables
the operator to restart the engines when he has
determined it is safe to do so. This switch is nec-
essary because diesel engines will consume fire
extinguishing agent and must be shut down by the
system when it is activated. The fire extinguishing
agent will shut down gasoline engines which can
be restarted once the fire extinguishing agent has
dissipated from the engine compartment. Refer
to the Automatic Fire Extinguishing System in
the Safety Equipment chapter and the manufac-
turer’s owner’s manual for more information on
the operation of the automatic fire extinguishing
system.
Spot Light (Optional)
Located in the helm. Controls the spot light that
is mounted on the deck. Refer to the spot light
owner’s manual for details on operating the con-
trol pad.
12-Volt Receptacles
Provides electrical current for portable 12-volt
equipment.
DC Accessory Breaker Panels
Power is distributed to most of the 12-volt acces-
sories through individual circuit breakers located
in the DC breaker panels. There are three DC
breaker panels, the engine compartment breaker
panel located in the engine compartment near
the main battery switches, the main DC breaker
panel located in the cabin on the AC/DC panel and
the helm breaker panel at the helm station below
the steering wheel. Main breakers located in the
engine compartment breaker panel protect the
system from an overload. Some 12-volt acces-
sories are operated directly by the circuit breaker
in the panel while others are operated by switches
fed by the panel breakers.
A DC voltage meter is located in the cabin panel to
monitor the voltage level in the House batteries.
It will monitor the voltage of the batteries plus
any electrical charges supplied when the engines
or the battery charger are operating.
PROPER fUSE OR bREAKER PROTECTION MUST
bE PROVIDED fOR ALL 12-VOLT EQUIPMENT
ADDED. DO NOT OVERLOAD THE ACCESSORY
CIRCUIT bREAKERS OR OTHER CIRCUITRY
THROUGH ADDITIONAL 12-VOLT EQUIPMENT.
Engine Compartment Panel Breakers
The following is a description of the accessories
controlled by the “push to reset” and main DC
breakers in the engine compartment breaker panel
located near the battery switches on the forward
engine compartment bulkhead.
Stereo Memory
Provides protection and power for the stereo and
electronics memory. This “push to reset” breaker
is always supplied current when the batteries are
connected.
