The automatic isolator controls the charging of all three battery
banks whenever one or both of the engines is operating.  When
one or both engines is started, the engine alternators start to
recharge the batteries.  This charging current passes through
the isolator sensing circuit.  This circuit senses the charge and
connects  the  charging  current  for  the  “House”  battery  bank
in parallel with the engine starting battery banks.  Thus the
charge from the engines is split between the batteries, with
the lowest battery bank receiving the most charge.  When the
engines are turned off, the charging stops and the sensing cir-
cuit disconnects the “House” battery bank from the cranking
batteries,  thereby  automatically  isolating  the  battery  banks
from one another.

Note: The diesel engines may have induction air heaters

to reduce smoke and improve cold weather start-
ing.  These heaters cycle on and off every 20 to
thirty seconds while the engines are warming up
and will cause the volt meters to ﬂuctuate,  The
ﬂuctuation is particularly noticeable at idle.  Once
the engines are started, monitor the volt meters
carefully.  If one or both of the volt meters read
below 12 volts after one minute, raise the engine
RPM to 1200  for several seconds then return them
to idle.  This will “excite” the alternators and cause
them to activate.

When in port or at anchor, the switch that supplies the port
engine and the switch that supplies the starboard engine should
be  off.    Only  the  battery  switch  that  activates  the  “House”
battery bank should be on.  This will keep the engine starting
battery banks in reserve for starting the engines.  All three bat-
tery switches should be in the “OFF” position when leaving
the boat unattended.

Note: Current is supplied to the high water alarms and

the automatic ﬂoat switches for the bilge pumps
when the batteries are connected and the battery
switches are off.

The DC electrical system on your boat is designed for wet cell,
marine batteries.  Do not attempt to use gel cell, absorbed wet
mat or other non wet cell batteries.  The engine charging sys-
tem and the battery charger are not designed to recharge these
batteries which could cause unusually short battery life, engine
starting problems and damage to the DC charging systems.  You
also should not mix the size or brand of the wet cell batteries.
Always  consult  your Albemarle  dealer  before  changing  the
type of batteries in your boat.

12-Volt Accessory Switch Panels

The main accessory switch panel and the engine switch panel
is located at the helm. The circuit breakers that protect the
accessories and activate the engine starting circuit are located
in cabin breaker panel.

The following is a description of the accessories controlled
by the engine switch panel:

Port Ignition Switch

The  port  ignition  switch  is  an  on  off  switch,  located  in  the
bottom side of the helm pod below the steering wheel, which
activates the port engine.   The switch has an off and on posi-
tion. A momentary start switch is located next to the ignition
switch.  To start the engine, make sure the shift lever is in the
neutral position and your hand is on the control lever in the
idle position.  Turn the ignition switch to on and activate the
start switch.  When the engine starts release the switch.  Stop
the engine by pressing the ignition switch to the off position.
It is protected by a breaker located in the cabin breaker panel
and a main breaker located on the engine.

Starboard Ignition Switch

The Starboard ignition switch is an on/off switch, located in the
bottom side of the helm pod below the steering wheel, which
activates the Starboard engine.   The switch has an off and on
position.  A momentary start switch is located next to the igni-
tion switch.  To start the engine, make sure the shift lever is in
the neutral position and your hand is on the control lever in the
idle position.  Turn the ignition switch to on and activate the
start switch.  When the engine starts release the switch.  Stop
the engine by pressing the ignition switch to the off position.
It is protected by a breaker located in the cabin breaker panel
and a main breaker located on the engine.
