Electrical System
charging. When the engines are started, the engine
alternators start to recharge the batteries. The
charging circuits sense the charge and it is split
between the batteries, with the lowest batteries
receiving the most charge. When the engines
are turned off, the charging stops and the sensing
circuits disconnect the batteries from the charging
circuits, thereby automatically isolating the batter-
ies from one another.
When in port or at anchor, the engine battery
switches should be off. Only the battery switch that
activates the House circuit and generator should
be on. This will keep the engine starting batteries
in reserve for starting the engines.
Notice:
Current is supplied to the automatic switches
for the bilge pumps when the batteries are
connected and the battery switches are off.
Notice:
The manual battery switches completely by-
pass the remotely activated switches when
the switches are manually activated. The
circuits cannot be turned off using the re-
mote battery switches on the helm panel if
the battery switches have been activated by
the manual switches.
