The monitor is protected by a reset and can not be turned 
except by the DC main breaker. 
7.3  System Components and Operation
The largest  part  of  your  controls  are on the 12 Volt DC 
Panel, we will run down the systems and components as 
they are listed on the Panel.  From there, we will look at  
the helm controls.
7.3.1  DC Main
In order to energize the DC system aboard your boat, you 
must turn the breaker marked “DC Main”, on the battery 
switch panel, to the “ON” position.  This supplies power to 
the remaining breakers and systems on the DC Panel.
7.3.1.1  To operate the 12 Volt DC System:
1.  Switch  the  main  battery  switch  under  chart  table  to 
ON.
2.  Switch  the  DC  main  circuit  breaker  at  battery  switch 
panel to ON.
3. Switch on relevant breakers at the MDP.
Note:  Always switch circuit breakers off  when  you  leave your 
boat unattended.
7.3.2 Lighting Systems
There are basically four different lighting systems aboard 
your  boat.    These  are  the  interior  (Cabin)  and  exterior 
lighting, the safety and navigational lighting, and, if sup-
plied, the courtesy lighting.
The interior and exterior  lighting systems are  separated 
because of the method in which power is supplied to the 
two systems.  The interior lights are powered from the 12 
Volt DC Panel and marked Cabin Lights as well as hav-
ing switches in the cabin. The exterior lighting is powered 
from the 12 Volt DC Panel as well and have switches on 
the helm for their operation.
 
The engine room and Lazarette (generator) area lighting 
are also powered from the 12 Volt DC Panel.
The  next  area,  safety  and  navigational  lighting,  closely 
follows  Coast  Guard  regulations  regarding  safety  and 
navigational lights.  They are as follows:
Nav Lights
Steaming Light
Mast Light
Deck Light
The red  and  green  lights on  the  bow  rail  and the  white 
facing light on the transom are known as “Nav Lights”.
These lights should always be on when motoring.
The “steaming” light is the forward facing light mounted at 
the top of mast. This should be on when underway with 
sail power only.
The  anchor  light  is  a  360  °  light  mounted  at  the  top 
of  the  mast  and  should  only  be  on  when  anchored. 
Lighting circuits and locations are outlined in the end of 
this chapter.
LPG bottle must always be firmly secured within 
their enclosure/locker.  
Flex-hose at stove must always run fair and be free     
of kinks and chafing.
Vapor drain must always be clear and clean of ob-
