Electrical System
The VSR battery isolator systems manage the
charging current for the 12 volt system whenever
the engines are running. The systems automati-
cally sense the condition of each battery and direct
the available current to the batteries that require
charging. When the engines are started, the en-
gine alternators start to recharge the batteries.
This charging current passes through the VSR
sensing circuits. The circuits sense the charge
and it is split between the batteries, with the low-
est battery receiving the most charge. When the
engines are turned off, the charging stops and the
sensing circuit turns off each VSR, disconnecting
the batteries from the charging circuit, thereby
automatically isolating the batteries from one
another.
When in port or at anchor, the engine switches
should be off. Only the battery switch that acti-
vates the House circuit and generator should be
on. This will keep the port and starboard engine
starting batteries in reserve for starting the en-
gines.
Triple Engine Boats
Triple engine boats are equipped with four bat-
teries located in the battery compartment behind
the aft berth in the cabin. One battery for the
port engine, one battery for the starboard engine
and two batteries in parallel for the center engine
and the house, generator and electronics circuits.
There are four remotely activated battery switches
and two remotely activated emergency parallel
switches located in the panel near the batteries.
The remote battery switches and emergency par-
allel switches are activated by special switches in
helm switch panel. Each battery or emergency
parallel switch has a manual override that can ac-
tivate (enable) or deactivate (disable) the switch
if the remote switch or relay fails. The manual
override is a yellow knob on each battery switch
that can be pressed to manually activate the
switch or rotated to reactivate remote activation
of the switch or to lockout the switch in the OFF
position when servicing the electrical system.
The normal operating position for each switch is
the “Enabled” Position. Refer to the instructions
printed on each switch and/or the battery switch
operating manual for additional information on
the remotely activated switches.
Remote Battery Switch Operation
Each battery switch and the emergency parallel
switches are controlled by a single switch in the
helm switch panel. Slide the label down and press
the top of the remote switch to engage the bat-
tery switch. A red light will illuminate to indicate
that the battery is now ON. To turn off, simply
slide the label up and press the bottom of the
momentary switch. The red light may not turn
off immediately or will slowly fade out if there are
no loads present on the system. This is normal
as the capacitors in the system drain.
Automatic Voltage Sensitive Relays (VSR) control
the charging of the engine and house batteries
whenever the engines are operating. The port
and starboard engine batteries can be temporarily
connected in parallel by the emergency parallel
switch in the helm to provide additional starting
current for those engines. The center engine
(triple engine boats) is connected to the house
batteries which are not connected to the emer-
gency parallel system, however, these batteries
will be recharged quickly by the port and starboard
engines when they are running. The engine and
house batteries are also charged by the battery
charger whenever it is activated.
