7.3.2 DC Panel Controlled Components
Please refer to the panel layout in Figure 7.9 for reference
in the following discussion. Please also note all switch
breakers discussed below will have a corresponding LED
light to the side of the switch to indicate an energized
system if the switch is in the “On” position.
NOTE: Always turn off circuit breaker switches when leaving
your boat unattended.
7.3.2.1 Volt Meter Battery Selector Switch
Immediately below the digital volt meter, located at the
top-right corner of the panel, is a three-position rocker
switch (“On-Off-On”) for selecting the battery for volt-
age display. One side of the switch is labeled “Start”
and other is labeled “House”. Position the switch to the
desired battery for a power level display. A charged bat-
tery will display a reading over 12 volts. The voltmeter
will display the voltage of the battery banks regardless if
the DC panel is energized or not.
7.3.2.2 Entertainment Breaker
This 40 amp switch breaker controls the optional enter-
tainment components of your boat. The breaker is
labeled “Entertainment” and protects the stereo, DVD,
speakers and TV circuitry from a power fault.
NOTE: Consult the entertainment component manufacturer’s
OEM manual for component operation, care and maintenance.
7.3.2.3 Refrigerator Breaker
This 15 amp switch breaker provides power to the refrig-
erator. It is labeled “Refrigerator” on the panel and pro-
tects it from a power fault.
7.3.2.3.1 Basic Refrigerator Operation
Choose the single battery power source by position-
ing the House Battery selector switch to “ON” or the
combined battery power source by positioning the
House Battery selector switch to “COMBINED” (5
o’clock) and the Start Battery selector switch to “ON”
(3 o’clock).
Position the “DC Main” breaker switch on the Battery
Switch Panel to the “On” position.
Position the “Refrigerator” breaker switch to the “On”
position.
To turn your refrigerator on, turn the fridge’s internal
temperature control knob clockwise to the desired
cool level.
To turn your refrigerator off, turn the fridge’s internal
temperature control knob fully counterclockwise.
NOTE: If leaving the refrigerator on when away from the boat,
ensure the shore power cables are connected. (If equipped
with a battery charger, turn it on to prevent battery drain. If
equipped with an inverter, the batteries will automatically charge
if the AC panel is energized.)
NOTE: Consult the refrigerator manufacturer’s OEM manual for
fridge operation, care and maintenance.
7.3.2.4 Freezer Breaker
The freezer information is the same as the refrigerator.
Please refer to the previous section.
7.3.2.5 Lighting Systems - Deck Light, Running
Lights, Anchor Light, Steaming Lights & Cabin
Lights Breakers
For consistency, we will discuss all switch breakers and
reset breakers for lighting systems aboard your boat.
There are basically two distinct lighting systems:
