GENERAL
All electrical equipment
on
Carver boats operates on
either 12 volt
DC
or 120 volt (220 volts on 50 Hertz
models) AC electrical power. An understanding of the
systems and their operation can be easily gained
through a study of the major components which
com-
prise the electrical circuitry. Section E describes the 12
volt system and the related operation. Also
in
Section E
is
a description of the 120 (220) volt system.

Installation
A single 12 volt
DC
battery
is
standard equipment on
certain models. A Battery Selector Switch (see the
Locator Drawing
in
Section 0 for the exact location
of
the Battery Selector Switch) is provided on models with
2 batteries.
Connect the battery
in
the following manner:
1. Connect the red battery cable from the Battery
Selector Switch to the positive
(+) terminal of the
battery.
2. Connect the black cable from the engine to the
negative (-) battery terminal.
3. Also connect the black lead from the power trim
pump, if so equipped, to the negative
(-)
battery termi-
nal.
4.
Other black leads for 12 voltequipment, such as
those labelled A, A
1,
and AD, must also be connected
to
the negative (-) battery terminal.

Operation
All factory installed 12 volt equipment, except for the
automatic bilge pumps and
the
voltmeter, are con-
nected to and controlled by the Battery Selector Switch
or
the main circuit protection device (either fuse
or
circuit breaker).
The OFF position of the Battery Selector Switch will
completely shut off 12 volt electrical power. The only
exceptions are the voltmeter (described in Section
E)
and automatic bilge pump (described in Section E).
Always turn the Battery Selector Switch to the OFF
position
or
place the main circuit breaker
in
the OFF
position when the boat
is
left unattended for an ex-
tended period.
Positioning the Battery Selector Switch to the
#1
posi-
tion will provide power to the 12 volt electrical system.
In single battery installations, the
#2
position of the
Battery Selector Switch is not functional.
I NPORT A NT: Extended use
of
12 volt equ ipment with-
out operating the engine
or
charging the battery cou
Id
seriously damage the battery.

Installation
The Battery Selector Switch (see the Locator Drawing
in
Section 0 for the exact location
o.f
the Battery
Selector Switch) that
is
provided
on
models with two
batteries enables
DC
power to be used from either
or
both batteries.
When installing the batteries, proceed as follows:
1.
Connect each
of
the two red cables leading from the
Battery Selector Switch to the positive (+) terminal on
each
of
the two batteries.
2.
Connect each of the black cables from the engine to
each
of
the negative (-) battery terminals. On dual
engine boats there will be one black cable coming from
each engine. Single engine boats will have two black
cables coming from one engine. Any black leads for the
power trim pump, etc. must also be connected to the
negative
(-)
battery terminal.
