Electrical Systems
4.1 General
Your Pursuit boat is equipped with a 12 volt
DC electrical system. The DC system draws
current from onboard batteries.
Electrical schematics are included in this
manual to assist technicians in the servicing
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 sys-
tem at any time without notice to the con-
sumer 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.
4.2 DC System
Batteries
The 12-volt batteries have been selected to
provide optimum performance for engine
starting, and house and electronics loads.
There are two, group 27, lead acid batteries.
These batteries require similar maintenance
to automobile batteries. The batteries are
located in the aft bilge. The starboard battery
is reserved for engine starting and the port
battery is the house battery. A circuit breaker
on the engine protects the engine ignition
systems and gauges. Refer to the engine
owner's manual for information on the circuit
breakers installed on your engines.
DC Distribution
The 12-volt DC system is made up of batter-
ies that are charged by the engine charging
system. Boats that are factory rigged with
Yamaha® engines utilize the Yamaha Bat-
tery Isolator to charge the engine cranking
battery and the house battery. The 12-volt
DC power
is distributed to the battery
switches and the circuit breakers on the
Main Distribution Panel (MDP), located
on
the starboard side of the cockpit. These cir-
cuit breakers protect the switches that are
located on the helm and in the head enclo-
sure.
The circuit breaker on the engine protects
the engine ignition systems and gauges.
Refer to the engine owner's manual for infor-
mation on your engines.
