ics at low speed when the charging system output
from the engine is minimal. Refer to the engine
owner’s manual for additional information on the
battery requirements for your engines.
There are two remotely activated battery switches
and one remotely activated emergency parallel
switch located in the aft systems compartment.
The remote battery switches and emergency par-
allel switch are activated by special switches in
the helm switch panel. Each battery switch has
a manual override that can activate (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 reac-
tivate 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
switch is controlled by a switch in the helm battery
switch panel. Slide the label down and press the
top of the remote switch to engage the battery
switch. A red light will illuminate to indicate that
the battery is now ON. To turn o, simply slide the

label up and press the bottom of the momentary
switch. The red light may not turn o 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 engine is operating. The house and
engine batteries can be temporarily connected
in parallel by the emergency parallel switch to
provide additional starting current for the engine.
The engine and house batteries are also charged
by the battery charger whenever it is operating.
