B. Operation
Power to the engines and all 12 volt electrical equipment
is controlled at the battery selector panel. On certain
Vista™ models, separate breakers are provided on
the battery selector switch panel to protect the stereo,
windlass, forward and aft bilge pump, battery outputs,
and ship systems.

Battery Selector Switch - Dual

The battery selector switch positions for the dual bat-
tery selector 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 fore and aft automatic bilge pumps,
stereo, and windlass. Always turn the battery selector
switches and the SHIPS SYSTEMS" circuit breaker
switch to the "OFF" position when the boat is unattend-
ed for an extended period.

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, stereo and windlass
receive power from the ships system battery
and remain on at all time regardless of battery
selector or ship systems switch position.
DO NOT turn the battery selector switch to the
"OFF" position while its corresponding engine

"ON" - Turning the switch to position "ON" will use the
port engine battery to power the port 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. The
isolator will allow any alternator to charge all three bat-
teries. "ON" is the recommended switch position for
normal boat operation. This position allows maximum
use of 12 volt equipment on the boat.
"SHIP SYSTEMS" - Turning the switch to position "SHIPS
SYSTEMS" will use only the ships system battery to
power the port engine and 12 volt engine related equip-
ment. The isolator will allow any alternator to charge all
batteries, but the boat systems (including the engine)
will operate off of the ships systems battery.
"PARALLEL" - With the battery selector switch in the
"PARALLEL" position, the port engine and ships sys-
tems batteries are connected in parallel. Both batteries
will be used by the engine and all 12 volt equipment.
All batteries will be charged by any alternator through
the isolator.
Starboard Engine Battery Switch:
"ON" - Turning the switch to position "ON" will use the
stbd engine battery to power the stbd engine and 12
volt engine related equipment. The ships system bat-
tery will not be used for any engine related equipment,
but will power all other 12 volt equipment on the boat.
The isolator will allow any alternator to charge all three
batteries. "ON" is the recommended switch position for
normal boat operation. This position allows maximum
use of 12 volt equipment on the boat.
