"OFF" - With the battery selector switch in the "OFF"
position, all 12-Volt power to the boat is shut off
completely except to the automatic bilge pump,
stereo memory, and accessories (if applicable).
Al w ays turn the battery selector switch to the "OFF"
position when the boat is removed from the water or
when the boat is not going to used for an extended
period of time.

"ON" (I) - When the battery switch is set to "ON",
current flows from the engine (start) battery to the
engine start circuit and ship's systems circuits.
B. Twin Engine - Dual Battery System
On certain models, dual batteries may be installed.
When installing the batteries, proceed as follows:
1. Installation
a. Connect each of the red (positive) battery cables
leading from the battery selector switch to the
positive (+) terminal on each of the two batteries.
NOTICE
Be sure the two red (positive) cables are installed
on the positive (+) battery terminals.
b. Connect each of the black or yellow (negative)
battery cables leading to the respective engine
blocks to the negative (-) battery terminal on each
of the two batteries.
Boat Systems - Section B
When disconnecting the cables from the battery,
make sure all switches are off and disconnect the
black
or yellow
negative cable(s) first to prevent
spark.
2. Battery Switch Operation
Power to the engine and all 12 volt electrical equip-
ment is controlled at the battery switch panel. Sepa-
rate circuit breakers are provided on the battery
selector switch panel to protect the bilge pump, stereo
memory, stereo amplifier, accessories, fresh water
pump and ballast pump where applicable. See Figure
B16.
The battery switch as described by the manufacturer
Blue Sea
Systems, (See Figure B18) "makes it
®
possible to switch two battery banks simultaneously
with one single ON/OFF switch. It eliminates the
confusion surrounding the traditional four-position
selector battery switch. The battery switch offers
simple ON/OFF switching and the isolated engine
start and ship's systems (house) circuits reduces the
chance of fully discharging both batteries. It also
protects house electronics from engine starting sags
and spikes as well as protecting engine electronics
controls from stray house line noise."
