SINGLE ENGINE - DUAL BATTERY
SYS TEM
A battery selector switch is installed when the boat is
equipped with a dual battery system. As previously
mentioned in Section H-1, each, the ships' systems
and engine, has an individual battery designated to it.
A. Installation
1. 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.
2. Connect each of the black or yellow (negative)
battery cables leading to the engine block to the
negative (-) battery terminal on each of the two
batteries.

When disconnecting the cables from the battery,
make sure all switches are off and disconnect the
black
spark.
B. 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 aft bilge and
forward bilge pumps, shower sump, stereo memory,
exhaust, and stereo amplifiers (if applicable). See
Figure H3.
As described by the manufacturer, the battery switch
(See Figure H6) 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.
