Chapter 4
Your Regal yacht uses 12 volt DC electricity otherwise
known as direct current. It is called DC because it fl ows
only one way in a circuit. Specifi cally 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 DC system used in the United States 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.
Th
is 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 batteries and
produced through the engine alternators while the
engines are running or by the battery charger at dockside.
Th
e alternators charge the batteries by sending current
through the main distribution panel relays, battery
switches and harnesses to the appropriate battery. Normal
DC voltage is between 12 and 15 volts. Lower or higher
readings could indicate a charging malfunction or a
weak battery.
Th
e Volvo diesel engine alternators used on your yacht
are internally self “excited” and produce DC current at
idle.
Current specifi cations for alternator output is 115 amps.
The IPS steering system needs additional operating
current and this is one reason the alternator output is
higher than conventional units.
Th
e port cranking battery controls the windlass, port
engine and generator.
Th
e starboard cranking battery controls the starboard
engine, forward bilge pump and high water alarm.
The house battery controls a variety of onboard
equipment functions..
DIRECT CURRENT (12 VOLTS)
BATTERY (12 VOLTS) DESCRIPTION
On board direct current is stored in the ship’s “wet cell”
batteries. Th
ere are 2 engine starting batteries (one for
each engine) and a deep cycle “house” battery.
