You should refer to the battery charger owner’s
manual to make sure the charger is set to the type
of batteries in your boat and do not mix the size,
type or brand of marine batteries. Always consult
your dealer before changing the type of batteries.
Parallel Start Switch and Dead Batteries
In the event of a dead starting battery for either
engine, the port and starboard engine batteries
can be placed in a temporary parallel configura -
tion. This allows you to start either engine from
both the port and starboard engine batteries. To
do this, locate the “PARALLEL START” switch at the
helm. Make sure the HOUSE battery switch is on.
Hold down the Parallel switch for 3 seconds, then
start the engine with the dead battery normally.
After 10 minutes, the PARALLEL START switch will
automatically disengage.
In the event of a dead house battery bank, there
are several options.
• If at the dock, simply plug in your shore power
and turn on the battery charger until the bat-
tery is recharged.
• If at sea, start the starboard engine. Once
the starboard engine is running, the alternator
will charge the starboard engine battery. As
the voltage in the battery raises to a preset
level, the automatic isolator relay between
the starboard engine battery and the house
batteries will close and direct charging current
to the house batteries. The starboard engine
battery and house batteries will continue to
be charged until the engine is shutdown and
the automatic relay opens, isolating the house
batteries from the engine battery.
To operate the battery switches remotely in Auto
Mode, the manual knob on each battery switch
must be set to “AUTO OFF.” In this position, each
battery switch will move from “AUTO OFF” to “AUTO
ON” when the remote switch is turned on and from
“AUTO ON” to “AUTO OFF” when the remote switch
is turned off. LED lights at the remote switches and
on each battery switch will be lit when the battery
switches are in the ON position. The LED lights at
the remote switches and on the battery switches
will be off and the battery switches will indicate
“AUTO OFF” when the battery switches are turned
off. Remote operation of the battery switches is
not possible when they are set to Manual Mode.
If auto operation is attempted, the LED lights will
flash for 3 seconds, then stop. The knob on the
battery switches must be set to “AUTO OFF” before
they can be activated remotely.
The remote operation of the battery switches can
be overridden at anytime by depressing the control
knob on the battery switch and turning it to the
“MAN ON” or “MAN OFF” position. The “MAN ON”
LED light on the battery switch will be lit whenever
the battery switch is activated in Manual Mode. The
knob on the battery switch must be returned to the
“AUTO OFF” position before the battery switch can
be activated remotely. For more information on
the motorized battery switches, refer to the switch
manufacture’s operation manual.
When in port or at anchor, the PORT and STAR-
BOARD ENGINE battery switches should be off.
Only the battery switch that activates the house
batteries should be on. This will keep both en-
gine starting batteries in reserve for starting the
engines. If the house battery bank becomes dis-
charged to the point that the accessories will not
operate or the optional generator will not start,
the starboard engine can be started to recharge
the house battery bank and, if equipped, to start
the generator.
Notice:
Current is supplied to the high water alarm
and automatic float switches for the bilge
pumps, sump pump , the electronic corrosion
controllers and the cabin CO monitor when
the batteries are connected and the battery
switches are off.
The DC electrical system on your boat is designed
for wet cell, gel cell or AGM marine batteries. The
battery charger is equipped with a switch to select
the type of batteries to be charged. The batteries
will be damaged if the charger is not set properly.
