Chapter 9: 2770/2780 Operation and Schematics
9.1 Operation of Standard Equipment
9.1.1 Battery Layout and Management
The 2780 is equipped with three batteries, which are located in the aft battery compartment on the tran-
som wall.. A cranking battery is installed on each side, and a dedicated house battery is installed in the cen-
ter. Wire leads run through the hull harness to the battery management panel which is located under the
helm seat. See section 6.5 & 6.6.1 for information regarding the operation of this panel. The engine crank-
ing leads run aft, through a hull rigging tube, The negative engine leads are connected to the common
battery ground using a negative buss also located in the aft rigging compartment.
The house battery provides the power for a majority of your DC accessories. The main battery lead runs to
the
“ HOUSE ” switch on the battery management panel. From there current is routed to the dash and circuit
breaker through the 50 amp “ DC Main ” breaker located in the left side of the battery management panel.
During normal operation this breaker can remain in the “ ON ” position, and the “ HOUSE ” switch can be used
to control the flow of current. The main ground for all DC accessories is tied into the common ground on
all batteries. For a detailed drawing of the battery management panel connections, see section 10.2.4.
9.1.2 Additional Emergency Parallel
As an additional feature, the 2770/2780 management panel contains a secondary “ EMERG PARALLEL ”
switch. It allows you to mechanically link the starboard “ cranking ” battery to the house battery. Further-
more, engaging both “ EMERG PARALLEL ” switches will connect all three batteries into a single bank. The
switches should remain in the “ OFF ” position when not in use. To prevent voltage spikes or drops which can
damage electrical components, you should trip the DC Mains 1 breaker prior to cranking engines with the
house battery in parallel. Once you are running, the breaker can be reset to allow the full alternator output
to power the electronics. This is a safety feature and should not be used in
- lieu of the VSR ’ s to charge bat-
teries while underway. Doing so, could result in premature battery failure and increases the risk of electrical
failure while at sea.
9.1.3 Bilge Pumps / Float Switches
Your 2780 is equipped with two 1500 GPH bilge pumps located aft and two 500 GPH pumps forward. Each
pump is connected to a float switch which automatically triggers the pump when water comes to rest in the
bilge. The float switches are connected to the battery management panel through the hull harness and re-
ceive power from the breakers on the right side of the panel. These breakers are constantly energized and
ensure the safety of your boat even when the battery switches are in the “ off ” position. The pumps can be
manually engaged using the switch at the dash.
The aft bilge pumps are located behind the aft rigging compartment and can accessed through the inspec-
tion plates in the motorwell, forward of the engines. The forward bilge pumps are located under the inspec-
tion plate in front of the head in the portside cabin and under the starboard side storage liner .. The wiring
for these pumps is secured to the centerline stringer which is visible from the hatch. Inspect the operation
of your bilge pumps and their con-nections at least annually. To do so, activate the pump by removing the
pump from the base and flipping it upside down. Then check the operation using the manual switch. Keep-
ing your bilge areas clean can also help extend the life of your pump.
