DC Electric Systems
7.13
The following components do not have a dedicated
switch or fuse on the main panels and are generally pro-
tected within the OEM wiring or separate breakers/fuses.
We will introduce these components and the method and
location of power and circuit protection.
7.4.1 Windlass Breaker
The optional anchor windlass is supplied power through
a breaker separate from the main panels. This 110 amp
windlass breaker is located in the aft cabin and mounted
on the inboard face of the engine compartment/compan-
ionway bulkhead and to the immediate right of the BSP
(Fig. 7.5).
To operate the windlass, rotate the yellow trip lever
counterclockwise into its cover flap. To de-energize the
windless, depress the red breaker button (the yellow trip
lever will flip downward). For additional details about
the optional windlass and anchoring, please refer to the
Underwater Gear chapter in this manual.
NOTE: If windlass becomes inoperable electrically, a manual
winch handle is supplied (see Underwater Gear chapter in this
manual for further details).
NOTE: Consult the windlass manufacturer’s OEM manual for
windlass operation, care and maintenance.
7.4.2 Engine Compartment Automatic Fire
Extinguishing System
The optional automatic fire extinguishing system consists
of a cylinder, mounting bracket, relay and remote circuit-
ry. It is powered through direct connection to the engine
starter and incorporates a 5 amp in-line fuse located near
the engine starter within the engine compartment.
The remote is part of the Fuel/Safety Panel (Fig. 7.16)
located on the forward starboard cockpit. If the engine
starter is energize but the fire extinguisher remote panel
“READY” light is not illuminated, check the system wiring
and in-line fuse and replace if necessary.
When a fire is detected on your boat, the automatic sys-
tem will sound an alarm, discharge the extinguisher and
illuminate the “DISCHARGE” LED on the Fuel/Safety
Panel. The relay will shut down the engine, the blower
and the optional generator.
When the critical portion of the emergency has
passed, the alarm and illuminated “DISCHARGE”
light can be turned off by setting the switch to the
“OVERRIDE” position. To reset the system, a full extin-
guisher cylinder must be installed. Set the switch to
“NORMAL” and verify the “READY” LED is illuminated.
NOTE: Consult the automatic fire extinguisher system manu-
facturer’s OEM manual for system operation and maintenance.
7.4.2 VHF Radio
The circuitry for the optional VHF radio is protected by
a 10 anp inline fuse. The fuse is located within the port
electronic component’s cabinet and accessed through
the cabinet face.
7.5 General Maintenance
Maintenance of your DC system simply involves ensuring
all connections are clean, tight, and covered with a corro-
sion inhibiting compound.
