Chapter 10: 2740 Operation & Schematics
10.1 Operation of Standard Equipment
10.1.1 Battery Layout and Management
The 2740 is equipped with three batteries, port and starboard cranking batteries are located in the aft battery
compartments on the transom wall. The house battery is located inside the helm storage area. Wire leads run
through the hull harness to the battery management panel which is underneath the helm seat. See section
6.5 & 6.6 thru 6.6.1 for information regarding the operation of this panel. The engine cranking leads run aft,
through a hull rigging tube, from the management panel to a positive stud mounted on the bulkhead in each
aft rigging compartment. 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 80 amp “DC Main” breaker located in the center 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.
10.1.2 Voltage Sensor Relay (VSR)
The twin voltage relay sensors are integrated into the battery switch cluster. They distribute the charging
output from the engine alternator to the “cranking” and “house” batteries. After starting an engine, the
alternator sends electricity back to the “cranking” battery to recharge it. Once the “cranking battery” is fully
charged (13.6 volts), the VSR closes to allow the alternator output to charge the “house” battery. When the
VSR is operating, the LED indicator located on the management panel will be lit. It will remain lit until the
battery is fully charged, or the “cranking” battery voltage falls below 12.8 volts. It is common for the VSR to
cycle “ON” and “OFF” during operation. However, constant cycling could indicate a problem in the system and
should be checked by your dealer.
10.1.3 Additional Emergency Parallel
As an additional feature, the 2740 management panel contains a secondary “EMERG PARALLEL” switch. It
allows you to mechanically link the starboard “cranking” battery to the house battery. Furthermore, 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 batteries while
underway. Doing so could result in premature battery failure and increases the risk of electrical failure
while at sea.
10.1.4 Bilge Pumps / Float Switches
Your 2740 is equipped with two 1500 GPH bilge pumps located aft. 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 receive 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 be accessed through the
inspection plates in the motorwell, forward of the engines. 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
connections at least annually. To do so, activate the pump by lifting the external float switch once released
the pump should shut off. Keeping your bilge areas clean can also help extend the life of your pump.
