NOTICE
DO NOT turn the battery selector switch to the
"OFF" position while the engine is running. Al-
ternator and wiring damage could result.
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.
"2" - Turning the switch to position "2" will use battery
#2. 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 paral-
lel. Both batteries will be used by the engine and all
12 volt equipment. Both batteries will be charged by
the alternator. However, the batteries will charge at a
slower rate compared to setting the switch in the other
positions.
The use of one battery at a time is recommended.
Position the battery selector switch to either the #1 or
#2 position.
Under normal conditions, avoid using the "ALL" posi-
tion. Use the "ALL" position only when a single battery
is not capable of starting the engine.
Four Winns recommends alternating between batter-
ies 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
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 "ALL" position) will supply a greater
charge to the battery.
FOR EXAMPLE: If battery #1 is fully charged and
battery #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.

2. Battery Switch Operation with "Emergency Start
Only" Position
A description of the various positions for this battery
switch is as follows:
"OFF" - With the battery selector switches in the "OFF"
position and the "SHIPS SYSTEMS" circuit breaker
in the "OFF" position, all 12 volt power to the boat is
shut off except to the automatic bilge pumps, stereo
and windlass (if applicable). Always turn the battery
selector switch to the "OFF" position when the boat is
unattended for an extended period.
NOTICE
Twelve volt power to the cabin panel is supplied
by the "SHIPS SYSTEMS" circuit breaker on the
battery selector panel. This must be turned on
to operate any 12 volt accessories on the cabin
panel. The bilge pumps and stereo receive
power from the ships system battery and remain
on at all time regardless of battery selector or
ship systems switch position.
NOTICE
DO NOT turn the battery selector switch to the
"OFF" position while its corresponding engine
is running. Alternator and wiring damage could
result.
"ON" - Turning the switch to position "ON" will use the
engine battery to power the engine and 12 volt engine
related equipment. The ships system battery will not be
used for any engine related equipment, but will power
all other 12 volt equipment on the boat (when "SHIP
SYSTEM" circuit breaker is on). The isolator will al-
low the alternator to fully charge the two batteries, but
not allow the operator to drain down the engine start
battery. "ON" is the recommended switch position for
normal boat operation. This position allows maximum
use of 12 volt equipment on the boat and leaves a full
charge in the engine battery for starting.
"EMERGENCY START ONLY" - With the battery selec-
tor switch in the "EMERGENCY START ONLY" position,
the engine and ships systems battery are connected in
parallel. Both batteries will be used by the engine and
all 12 volt equipment. Both batteries will be charged
by the alternator through the isolator.
