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.
