that the two engine switches and the house switch
are activated whenever the engines are running
to ensure that all 12-volt accessories will operate
when they are needed.
Each battery switch relay in the engine compart-
ment has a manual override that can activate or
deactivate the switch if the relay fails. The manual
override is a red knob on each battery switch/re-
lay that can rotated to select the “ON”, “AUTO” or
“OFF” position. When a battery switch is activated
manually, the red knob must be rotated to the
“OFF” position and then to “AUTO” before the bat-
tery switch/relay can be activated by the remote
rocker switch in the cabin breaker panel.
An automatic isolator/relay controls the charging
of the starboard engine and house battery banks
whenever the starboard engine is operating. The
port engine battery is dedicated to starting and
operating the port engine. It is charged by the
port engine whenever the port engine is operating.
The port and starboard engine batteries can be
temporarily connected in parallel by the parallel
switch in the helm to provide additional starting
current for each engine. The engine and house
batteries are also charged by the battery charger
whenever it is operating.
When in port or at anchor, the port and starboard
engine switches should be off. Only the battery
switch that activates the House battery should be
on. This will keep both engine starting batteries
in reserve for starting the engines. If the house
battery bank becomes discharged to the point that
the optional generator will not start, the starboard
engine can be started to recharge the house bat-
tery bank enough to start the generator.
Note: Current is supplied to the high water
alarm and the automatic fl oat switch-
es for the bilge pumps when the bat-
teries 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.
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.
The batteries in your boat were supplied by the
dealer. Always consult your dealer before chang-
ing the type of batteries.
