BATTERIES:
The DC Power source on your 43SB is
from batteries. There are three (3) banks
of batteries. The three banks of batter-
ies are the Starboard, Port, and Genera-
tor batteries. All Battery Banks are in the
Engine Room. The quantity of each bank
depends on the options. All batteries are
12 volt.
NEGATIVE GROUND SYSTEM
The negative terminal of each battery is
attached to a grounding stud on each en-
gine. This is known as a “Negative Ground
System” and is the approved system for
marine DC Electrical Systems. The bat-
tery wiring system has two (2) color-coded
wires. The yellow wire is the ground (neg-
ative) wire and the red wire is the positive
(hot) wire.
The DC Power from each battery Bank
goes to different locations:
Starboard Battery Bank -
