The port battery switch activates the port engine and the 12-
volt breaker panel in the cabin and all other 12-volt accesso-
ries, the starboard battery switch activates the starboard en-
gine, and the genset battery switch activates the generator
engine circuit and the circuit for the optional bow thruster.
Make sure that the port engine, starboard engine, generator
and the DC accessory breakers are in the "ON" position when-
ever the engines are running to insure that all 12-volt acces-
sories will operate when they are needed.
When the engines are started and the battery switches are on,
the engine alternators will recharge the batteries. The batter-
ies are also charged automatically whenever the AC system
is activated by shore power or the generator and the battery
charger is activated. The battery switches do not have to be
on to charge the batteries with the battery charger.
An automatic isolator controls the charging of all three bat-
tery 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 engine bat-
tery banks in parallel with the generator starting battery bank.
Thus the charge from the engines is split between the batter-
ies, with the lowest battery bank receiving the most charge.
When the engines are turned off, the charging stops and the
sensing circuit disconnects the battery banks, thereby auto-
matically isolating the battery banks from one another. The
system is equipped with a battery parallel feature that will
connect the engine starting batteries in parallel for extra bat-
tery power while starting the engines.
Note:
Some diesel engines may have induction air heat-
ers to reduce smoke and improve cold weather
starting. These heaters cycle on and off every 20
to thirty seconds while the engines are warming
up and will cause the voltmeters to fluctuate, The
fluctuation is particularly noticeable at idle. Once
the engines are started, monitor the voltmeters
carefully. If one or both of the voltmeters 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 star-
board engine and the switch that supplies the generator en-
gine should be off. Only the port battery switch should be
on. This will keep the starboard engine and generator start-
ing batteries in reserve for starting the engines. All three
battery switches should be in the “OFF” position when leav-
ing the boat unattended. If all the battery switches are left
"ON" when the boat is at rest and unattended, it is possible
for all of the primary engine starting batteries to go dead if
12-volt accessories are left on.
