SYSTEM OPERATIONS-17
Fuel fumes in the engine compartment
can explode. Before working on any
electrical wiring, ventilate the engine
compartment and disconnect the bat-
teries to prevent sparking.
NEVER reset a breaker switch which
has tripped automatically without fi rst
locating and correcting the problem.
The electrical system and devices may
be damaged.
Alterations or extensions to the electri-
cal system can cause electrical shock
or fi re. ONLY competent marine elec-
tricians should make system changes
according to U.S. Coast Guard regula-
tions.
Auto Bilge Switches - The Auto Bilge
Switches are located below the Gen-
erator Switches. There are three sets of
switches. These switches are used to test
the bilge pumps. Each set has an ON/OFF
Switch and a Reset Switch. There is one
set for each of the Bilge Pumps; Forward,
Mid and Aft. The DC Power to these
switches comes from the breaker located
between the Port and Starboard Battery
Switches.
Flybridge Switches - Below the Auto Bilge
Switches are two Switches. They are the
Flybridge Electric and the Electronics
Main Switches. Both switches get their
power from the Port and Starboard Battery
Switches. Both these switches turn on and
off the DC Power to the Helm Accessory
Switches.
Main Breaker Section - The Main Breaker
Section has two columns of switches.
The top breaker on each column turns all
switches below it on and off. The Main
Battery 1 breaker controls all breakers
in the left column below the breaker, the
Main Battery 2 breaker controls all the
breakers in the right column below the
breaker. The Main Breaker 1 breaker gets
its’ power from the Port Battery Switch,
and the Main Battery 2 breaker gets its’
power from the Starboard Battery Switch.
FUSE BOX - Behind the DC Panel is a
fuse box.
Turn off all electric power to your AC/
DC Panel when opening the door to the
electrical cabinet. The power can be
turned off by the two main DC switches
at the top of the panel, and the main AC
switch in the AC portion of the Panel. In
addition, make sure to remove all shore
power cords, and shut down the Gen-
erator. Do not forget the breaker for the
memory.
The fuse box can be divided into two
separate categories: Those fuses that are
constantly “ON” and those that are not
constantly “ON”.
Constantly “ON” fuses - The constantly
“ON” fuses get their power from the break-
er between the Port and Starboard Battery
Switch.
