Typical Battery Charger
Battery Charger
The 3 bank battery charger is mounted near the
batteries in the aft systems compartment. If your
boat is equipped with the trolling motor option,
it will be equipped with another 3 bank charger
dedicated to the trolling motor batteries. The
trolling motor battery charger operates the same
as the engine and house battery charger. It will
automatically charge the trolling motor batteries
when activated.
AC electrical current is supplied directly to the
battery charger by the shore power cable. The
charger automatically charges and maintains the
engine and house batteries simultaneously when
activated. It is equipped with led lights to indicate
the state of charge for each battery.
The charge to the engine battery can be monitored
by using the volt meters in the engine gauge clus-
ter or the LED lights on the charger. To monitor the
engine battery with the volt meters in the engine
gauge cluster, activate the charger and turn the
engine battery switch on. Turn the ignition key
switch to the ON position (DO NOT START THE
ENGINE) and read the voltage on the volt meter.
If the batteries are in good condition and charging
properly, the volt meter will indicate between 12
and 14.5 volts. If the reading is below 12 volts,
then the battery is not accepting a charge or the
charger is not working properly. Always turn the
ignition switch o immediately after the monitor-
ing is complete.
The wires that supply DC charging current to
the batteries are protected by an internal fuse in
the battery charger and external fuses or circuit
breakers, one for each battery output wire, located
near each battery. The external fuses protect
the DC charging circuit from the batteries to the
charger. The internal fuses in the charger protect
the DC charging circuit from the charger to the
batteries. Refer to the battery charger manual for
more information.
6.10 Bonding System
Your boat is equipped with a bonding system that
interconnects the underwater metal hardware and
the engine to ensure that they are of the same
electrical potential. Sacricial anodes of the size
and type recommended by the engine manufac-
turer are attached to the outboard motor. There
could also be sacricial anodes on each trim tab
plane that are isolated from the boat bonding
system to protect each tab plane assembly if the
boat is to kept in salt water.
Anodes deteriorate before the other metals, there-
by protecting the underwater metals from galvanic
corrosion or stray electrical current. Since the
anodes are sacricial, it is important to monitor
them and replace the anodes when they have
deteriorated to 50 - 75% of their original size.
The bonding system is connected to the engine
and battery DC ground. If your boat is equipped
with the optional battery charger, the earth ground
wire for the AC electrical system is also connected
to the bonding system. It provides a path to the
safety earth ground in the event of a fault in the
shore earth ground connection.
