Electrical System

4.1 General

Your Pursuit is equipped with a 12-volt DC

electrical system and draws current from on-

board batteries. The AC system draws cur-

rent from one of two sources, either shore

power outlets at the dockside or the genera-

tor.

Electrical schematics are included in this

manual to assist technicians when servicing

the electrical systems. Pursuit does not rec-

ommend that you attempt to service or mod-

ify the electrical system yourself. We

recommend that you take your boat to an

authorized Pursuit dealer for service or

installation of additional electrical equip-

ment. 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.

4.2 DC System

Batteries

The 12-volt batteries in your boat provide

optimum performance for engine starting,

house lights, and electronics loads. There

are three batteries located in the aft bilge;

one for each engine and a house battery.

They require similar maintenance to those

found in automobiles.

DC Distribution

The 12-volt DC system comprises of batter-

ies that are charged by the engine charging

system or by the battery charger when con-

nected to shore power or when operating the

generator. An automatic voltage control sys-

tem manages charging of the batteries

whenever the engine is running or when

operating the generator. 12-volt power dis-

tributes to the battery switches (located in

the machinery space) and to the breakers on

the Main Distribution Panel (MDP) (located

on the side of the helm seat) that protect the

switch panels located on the helm, in the

cockpit, and in the cabin. The voltmeter on

the MDP monitors battery voltage for the

house battery. The respective tachometer

monitors engine battery voltage.

Circuit protection devices on each engine

protect the engine, ignition systems, and

gauges. Please refer to the engine owner's

manual for information about your engines.

Battery Switches

Battery Switch Panel

There are three battery switches and two

parallel switches along with a Voltage Sensi-

tive Relay (VSR) to manage the 12-volt

power distribution. Turn the switch so the

green "ON" indicator illuminates. All battery

switches should be in the "ON" position

whenever the boat is in operation.

The Port Start switch controls the battery for

the port engine. The Starboard Start switch

controls the battery for the starboard engine.

The House switch provides power to the

house circuits. The starboard engine or the

battery charger charges the house battery.

The VSR prevents both batteries from dis-

charging by automatically isolating the

engine battery. A red light on the VSR indi-

cates charging of the house battery.

! CAUTION

Compartments on a Pursuit boat can

be lighted for night use. Light bulbs

generate heat and can ignite ordinary

combustibles causing a fire. Do not

place or store combustible materials

in contact with light bulbs. Turn off all

lighting prior to leaving the boat.
