Battery Switch Operation - Four winns FREEDOM Owner's Manual

When installing dual batteries, proceed as follows:
1. Connect each of the red battery cables leading from
the battery selector switch to the positive (+) termi-
nal on each of the two batteries.

NOTICE
Be sure both cables are installed on the posi-
tive (+) battery terminals.
2. Connect the black battery cable to the port negative
(-) battery terminal (see Section H-2). Connect the
other black battery cable to the starboard negative
(-) battery terminal.
When disconnecting the cables from the bat-
tery, make sure all switches are off and discon-
nect the black negative cable(s) first to prevent
spark.
C. Battery Switch Operation - (
Dual batteries with a selector switch is optional on cer-
tain models only. Power to the engine and all 12 volt
electrical equipment with the exception of the automatic
bilge pump is controlled by the battery selector switch.
See Figure H2.
Dual battery selector switch positions:
"OFF" - With the battery selector switch in the "OFF"
position, all 12 volt power to the boat is shut off com-
pletely except to the automatic bilge pump. A separate
fuse is provided on the battery switch panel for the auto-
matic bilge pump. Always turn the battery selector switch

to the "OFF" position when the boat is removed from the
water.
ENGINE
"1" - Turning the switch to position "1" will use battery #1
to power the engine and 12 volt equipment. Battery #2
will be isolated and remain in reserve. Only battery #1
will be charged by the alternator.
STARTER
SOLENOID
"2" - Turning the switch to position "2" will use battery #2
to power the engine and 12 volt equipment. Battery #1
is isolated and remains in reserve. Only battery #2 will

be charged by the alternator.

"BOTH" - With the battery selector switch in the "BOTH"
position, the batteries are connected in parallel. Both
batteries will be used by the engine and all 12 volt equip-
ment. Both batteries will be charged by the alternator.
However, the batteries will charge at a slower rate com-
pared to setting the switch in the other positions.
The use of one battery at a time is recommended. Posi-
tion the battery selector switch to either the #1 or #2
position.
Under normal conditions, avoid using the "BOTH" posi-
tion. Use the "BOTH" position only when a single bat-
tery is not capable of starting the engine.
Four Winns recommends alternating between batteries
during boating. Depending upon boating use, this may
increase battery longevity. Use battery #1 for the first
day of a cruise and switch to battery #2 on the second
day.
Position the battery selector switch to the battery that
Specific Models Only)
has sufficient power to start the engine (normally posi-
tion "1"). After the engine is running, turn the battery
selector switch to the battery that has the lowest charge.
This will allow the alternator to charge the low battery.
Utilizing the battery selector switch in this manner (in-
stead of using the "BOTH" position) will supply a greater
charge to the battery.
FOR EXAMPLE: If battery #1 is fully charged and bat-
tery #2 is in need of a charge, use battery #1 to start the
engine. After the engine is running and warmed-up, turn
the battery selector switch to the #2 position. This will
permit the alternator to charge the low, #2 battery.
NOTICE
DO NOT turn the battery selector switch to the
"OFF" position while the engine is running. Al-
ternator and wiring damage could result.
