Electrical Systems
4.1 General
Your Pursuit boat is equipped with DC and
AC electrical systems. The DC system draws
current from onboard batteries. The AC sys-
tem can draw current from either dockside
power outlets or the generator.
Electrical schematics are included in Appen-
dix F to assist technicians in the servicing of
the electrical systems. Pursuit recommends
you take your boat to an authorized Pursuit
dealer for service or installation of additional
electrical equipment. Pursuit reserves the
right to modify or update the electrical system
at any time without notice to the consumer or
obligation to make updates to boats built prior
to the change.
Some compartments on your boat may be
lighted. Lights bulbs produce heat and can
ignite combustible products. Turn off all light -
ing before you leave the boat.
WARNING
!
FIRE OR EXPLOSION HAZARD
Ignited combustible products can
cause fire or explosion, resulting in
death or serious injury. DO NOT store
combustibles near lights and turn off
all lighting before leaving the boat.
4.2 DC System
Batteries
The 12-volt batteries have been selected
to provide optimum performance for engine
starting, house, and electronics loads. There
are eight (8) batteries. Four (4) lead acid
batteries are located in the port mechanical
space compartment and three (3) AGM bat-
teries for house and electronics are located
in the starboard mechanical space compart-
ment. The batteries are located on heavy duty
sliding trays under the deck in the mechan-
ical space. To inspect the battery condition
remove the ¼” pull pin holding the slide in
place. Slide the entire tray inboard to gain ac-
cess to the batteries and their electrical con-
nections. One (1) AGM battery for the bow
thruster is located forward of the berth and
may be accessed by removing the mattress
and opening the forward berth access pan-
el. The AGM batteries are maintenance-free.
Refer to the engine owner’s manual for infor-
mation about the circuit breakers installed on
your engines.
DC Distribution
The 12-volt DC system batteries are charged
by the engine charging system or the battery
charger when connected to shore power or
when operating the generator. 12-volt pow-
er is distributed to the battery switches and
breakers on the DC Main Distribution Panel
(MDP). The DC MDP is located on the star-
board side of the helm seat base. Battery
switches and breakers on the DC MDP pro-
tect the switch panels on the helm and in the
cabin. Use the volt meters on the DC MDP to
monitor the battery voltage for the house and
electronics batteries. Use the multi-function
display at the helm to monitor engine battery
voltage.
The circuit breaker on each engine protects
the engine ignition systems and gauges. Re-
fer to the engine owner’s manual for informa-
tion on your engines.
Battery Switch Panel Feeds
The house and electronics breakers, located
on the battery switch panel feed located in
the port aft side of the machinery space (just
forward of the shore power cable reel), dis-
connect ALL battery power to the electronics
and house battery switch. If the boat is stored
out of the water, turn off the house and elec -
tronics breakers to ensure there is no electri-
cal drain from the associated batteries.
