10.1.1 Battery Layout and Management
The 290DC is equipped with three batteries, which are located in the helm storage compartment. They can be reached
using the access hatch located on the floor in the aft section of the starboard liner. A cranking battery is installed on
each side, and a dedicated house battery is installed in the center. Wire leads run across the liner and aft through a
hull rigging tube, to the battery management panel located on the inboard wall of the port seatbox. See section 6.5
thru 6.5.4 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 through the 50 amp “DC
Mains 1” breaker located on the top left corner 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. The “DC Mains 2” breaker
controls the DC panel located in the head compartment. The panel houses the breakers for the Windlass, Marine
Head, Hardtop Power Supply, and lighting in the head compartment. The panel is powered by the Stbd Start switch,
to prevent overloading of the House circuit. For a detailed drawing of the battery management panel connections, see
the diagram in section 10.4.5
of this chapter.
10.1.2 Additional Emergency Parallel
As an additional feature, the 290DC 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.
10.1.3 Bilge Pumps / Float Switches
Your 290DC is equipped with two 1500 GPH bilge pumps. 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 at the top right corner 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 bilge pumps are located behind the aft rigging compartment and can accessed through the inspection plates in the
motorwell, forward of the engines. The wiring for these pumps is secured to the inboard side of 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.
