Electrical Systems; Single Battery System; Dual Battery System - Four winns Horizon 210 Owner's Manual

H - 1 GENERAL
All electrical equipment on Four Winns® boats operate
on 12 volt DC electrical power.
Fire or Explosion Hazard!
Electrical system parts are designed by and
manufactured to comply with the U.S. Coast
Guard requirements to minimize risks of fire
or explosion. Never substitute automotive
parts for marine parts. Automotive parts do
not provide the necessary ignition spark pro-
tection.
To prevent equipment or electrical wiring dam-
age, DO NOT tamper with any electrical con-
nection, panel or harness, or attempt installa-
tion of any electrical equipment unless thor-
oughly familiar with the systems and are experi-
enced in making such installations.
For detailed information on the electrical system, electri-
cal schematics are located in the back of this manual.
H - 2 BATTERY SYSTEM
A. Single Battery System
On most models, a single battery is provided as stan-
dard equipment (12 volt DC) per Section H-1 above. The
dash components are protected by a fuse panel located
below the helm. Refer to Figure H1 and to the wiring
schematics in the back of this manual.
When installing the battery, proceed as follows:
1. Connect the red (positive) cable running from the
engine starter solenoid to the positive (+) battery ter-
minal.
2. Connect the black (negative) battery cable running
from the engine block to the negative (-) battery ter-
minal.
