Electrical System
Introduction
In this section, basic DC (direct current) is
introduced. Select electrical components are
reviewed along with their location and function
within the electrical system.
For more complicated issues outside the scope of
this manual contact your closet Regal dealer. They
have undergone extensive training on the Regal
boat systems.
Be sure to read and follow any danger, warning,
caution, or notice labels in reference to the
vessel’s electrical system or individual equipment
components. Also, refer to the owner’s information
packet for further product information or the internet.
PREVENT SEVERE INJURY OR DEATH!
DISCONNECT
ALL ELECTRICAL POWER SOURCES
BEFORE ATTEMPTING
TO REPAIR OR REPLACE
ANY ELECTRICAL COMPONENT.
WARNING
DC Current
Your Regal boat uses 12 volt DC electricity otherwise
known as direct current. It is called DC because it
flows only one way in a circuit. Specifically to name
a few, helm gauges, batteries, battery cables, engine
electrical components, engine wiring harnesses,
dash switches, selected lighting, shower sump,
bilge pumps, and vacuum toilets are all components
using a 12 volt DC system.
In the domestic DC system the red wire is
designated as the “hot” or conductor wire and the
black wire is referred to as the ground wire. At times
other current carrying wires are color coded such as
blue to identify their use as a low voltage conductor.
This is especially helpful in troubleshooting and
adding additional equipment. Be sure to review
the wiring schematics in the drawing section of the
technical chapter.
Direct current is stored in the ship’s battery(ies)
and produced through the engine alternator while
the engine is running or by the battery charger at
shore. Normal DC voltage is between 12 and 15
volts. Lower or higher readings could indicate a
charging malfunction or a weak battery.
Note that current specifications for alternator output
is around 105 amps depending on engine model .The
forward bilge pump and automatic float switch are
continuously on with the bilge pump switch in the
middle or “off” position. Should a leak develop with
the operator away from the vessel the bilge pump
will continue to pump bilge water overboard until
of course the battery goes dead.
AVOID CHARGING SYSTEM DAMAGE!
DO NOT TURN
BATTERY SWITCH TO THE “OFF”
POSITION WITH THE ENGINE RUNNING.

Batteries
All vessel DC equipment and specifications are
subject to change at any time, as part of Regal’s
commitment to product improvement. Equipment
information here is up to date per the owner’s
manual printing date.
Battery Terminology Descriptions
One battery is standard equipment on your ves-
sel. A second battery is used when the dual bat-
tery switch option is chosen. All batteries include a
battery box or tray along with fastening hardware.
Be sure to periodically check maintenance style
batteries for proper electrolyte levels and use only
distilled water when filling cells.
Group- Batteries are divided into groups which
identify the height, length, and width of the battery.
This is useful information should a replacement
battery become necessary. Note that the LS & LX
vessels currently use 31 A series battery (ies).
Cold Cranking Amps (CCA)- This rating mea-
sures the cranking power of a full charged marine
battery having the ability to start at 32 degrees F.
Basically, the higher the rating the greater starting
power of the battery.
Reserve Capacity (RC)- As usage on the boat
increases so does the need for more reserve ca-
pacity. The reserve capacity represents the length
of time in minutes a new fully charged battery can
maintain the vessel’s electrical needs without the
engine running or in the event of alternator failure.

1. Weak battery- This battery problem
can be caused by low electrolyte cell
levels.
Warm, bilge compartment
temperatures will deteriorate a battery’s life quicker
by evaporating the water from the electrolyte, thus
corroding and weakening the positive grids inside
the battery.
Low electrolyte levels can be monitored by periodic
inspection and filling as needed with distilled water.
Boaters in higher climate areas with longer stretches
of hot weather will need to check their batteries
more often.
“Maintenance free” engine cranking batteries
require no water and cells are not accessible.
They do feature a different chemistry that does
consume less water. Inside the cells as gases are
released condensation is formed which aids in
maintaining the cell electrolyte level. These batteries
incorporate a deeper layer of electrolyte over the
plates, but eventually it can run dry. On the 31 series
engine cranking batteries keep all terminals clean,
connections tight and your electrical system in top
shape to extend battery life.
2. Dead Battery- Either the battery will not accept
a charge, hold a charge or the charging system is
not supplying a charging current through the battery
charging system and/or engine alternators.
The battery charger output can be checked by
monitoring the lights on the charger front face.
To begin with check the battery post connections
for tightness and corrosion.
With the engine running the displayed voltage of the
battery should be between 12.5 up to 14.6 volts.
Battery Problems/Solutions If less than 12 volts check for voltage across the
battery terminals.
If less than 12 volts check with a hydrometer to
locate faulty cells.
Maintenance free batteries they can be removed
from the vessel if necessary and trickle charged.
If readings after charging are still low replace the
battery.

12
Battery Switch
The engine cranking battery switch is located in
the starboard bilge (sump) on the battery man-
agement panel. To access the panel lift up the star-
board aft seat.
The dual battery switch designates “off”, “on” and
“combine batteries” positions. This particular bat-
tery switch is connected to dual batteries and this
set-up supplies additional reserve capacity to run
higher amerage draw equipment on one battery
bank and to supply cranking amperage to start the
engine with the other battery bank.
To use the “combine batteries” feature for engine
starting when one battery bank is weak turn the
battery switch knob to the “combine batteries”
detent (yellow labeled area). At this point you can
start the engine.
As this particular battery switch features a “make
before break” footprint once the engine starts you
can reposition the battery switch to the “on” de-
tent which will revert back to the engine starting
battery. It is recommended not to leave the dual
battery switch in the “combine batteries” position
as under the right conditions a severe discharge
could result in both batteries becoming “dead”.
Never turn the battery switch to the “off” position
with the engine running.
Note that the battery charging system will recog-
nize a low or weak battery and will send a charge
to the weak battery when the outboard motor is
running.
The engine and house battery system is protected
by a breaker at the battery management panel.
Be sure to turn the battery switch to the “off” posi-
tion when leaving the vessel as the bilge pump (s)
will remain active in the automatic position. In addi-
tion, the stereo memory system will be protected.

Typical Battery Management Panel
The battery management panel features key elec-
trical components including battery switches,
breakers, fuse panels and related battery charging
components. The panel is accessed by lifting up
the aft starboard cushion. Here are selected com-
ponents you may find on the panel:
1. This 40 amp breaker controls power to the op-
tional anchor windlass. An 80 amp breaker is used
for optional PowerTower. There may be other simi-
lar breakers depending on the option protected.
2. This 50 amp breaker protects the dash or helm
circuit.
Note that the above breakers are shown in the “off”
position. Activate the above breakers push the yel-
low lever down until it ratchets in the “on” position.

3. This fuse protects the stereo memory circuit.
This allows you to keep all your stereo program
selections when you leave your vessel even with
the battery switch turned off.
4. This fuse protects the aft bilge pump which is
usually found in the bilge just forward of the en-
gine. When you leave the vessel and turn off the
battery switch as recommended the bilge pump
circuit is still activated allowing the pump to work
should a leak develop.
5. The battery switch when off disconnects any
voltage to the dash including the engine key
switch. Note that the standard battery switch in-
stead of the dual switch may be present on your
battery management panel.

Battery Management Panel (Continued)
Above is the battery management panel shown as
an inside view. This view would be facing the star-
board side of the engine.
1. Shown is a 10 amp battery charger. It sup-
plies DC current to assist in keeping the batteries
charged at shore. Be sure to read and understand
the recommendations on how and where to use
the battery charger (see previous pages).
2. These 15 amp fuses protect each of the battery
circuits. If the positive and negative battery cables
are somehow reversed these breakers could trip.
3. The automatic charging relay (ACR) controls the
flow of charge current from the battery charger to
the appropriate battery. The ACR is only used on
the dual battery switch system.
The ACR requires no maintenance and there are
no adjustments since it is a digital component but
check the wires periodically for tightness.

Battery Management Panel (Continued)
4. The ground block is a home for a group of neg-
ative (black) wires. You may even find an earth
ground on the block (green). This may be an ad-
ditional ground area for added accessories. Peri-
odically check to ensure all wires are fastened se-
curely. When adding accessories never add more
than 4 connectors to any stud on a ground block.
5. This bank provides a junction for wiring from
the battery charger circuits and from the ACR unit.
Periodically check wires for secure fastening.
6. Battery switch (rear view). See earlier informa-
tion for additional details. Note the red boots on
the rear of the battery switch. Periodically check to
ensure the boots cover the nuts securely and that
the connections and nuts are tight. Disconnect the
battery (ies) positive or + wires before tightening
the battery switch nuts.

Lift up the starboard bow backrest to access the
DC fuse panel. This panel protects many of the di-
rect current devices along with their circuit wiring
that are found on board your vessel. See the photo
on this page.
Below we will acquaint the operator with the func-
tion of each fuse and information regarding the
related component. These mini fuses can be pur-
chased at most auto and marine supply houses.
Never replace a fuse with a higher rated fuse to
prevent possible fire or component damage. Al-
ways find the reason why the fuse “blew” before
replacing it.
NAV/ANC- This 10 amp fuse protects the bow
light located on front deck the deck mounted stern
light. With the optional PowerTower an all around
light is used verses the stern light.
CPT/CAB LTS- A 10 amp fuse protects the blue
LED style blue cockpit lights which allows safer
night maneuvering throughout the cockpit.
DOCK LTS- This 15 amp fuse protects the option-
al hull docking lights which are used for maneuver-
ing in tight quarters at night. It is recommended
that the docking lights be off when running above
idle speeds at night since they might blind another
boater from being able to see the bow light.
GARMIN- This 2.5 amp fuse protects the
chartplotter(s) which show engine vitals along with
GPS information.
U/WTR LTS The 10 amp fuse protects the stern
mounted underwater lights.

CPT HEATER- This 15 amp fuse protects the
cockpit heater which is available on surf models.
BLOWER- This 5 amp fuse protects the ventilation
blower. This powered system removes any fumes
and bilge air and provides an exit to the atmo-
sphere through ducting located in the lower third
of the bilge. Check these 4” black hoses periodi-
cally for their condition and fastening of hardware.
BILGE- The fuse protects the bilge pump and its
circuit wiring located in the bilge. This pump fea-
tures a dash switch automatic center position. Re-
member that your vessels bilge pump system with
the automatic position is “on” even with the main
battery switch turned off at the battery manage-
ment panel.
STEREO- This 10 amp fuse protects the Fusion
stereo circuit. Note that if stereo performance and
lighting package is ordered there are additional
fuses located in the system such as at the ampli-
fier unit.
12 VOLT RECPT- This 15 amp fuse protects the
12 volt receptacles on the vessel. These can be
used to power accessories or with the correct
adapters to charge phones and tablets.
GAS VAP- This 3 amp fuse protects the option-
al gas vapor detector system. There is a sensor
mounted in the bilge and a head unit close to the
helm. If the sensor finds gas fumes in the bilge it
sounds an alarm.
HATCH- This fuse position is not currently being
used. With that being said the operator could use
this one for protecting an after market accesso-
ry. Always ensure your fuse amperage allows the
component a safety margin.
