10.1.1 Battery Layout and Management
The 290EC is equipped with three batteries, which are located in the helm leaning post. They can be reached using
the access hatch located on the forward vertical wall of the leaning post. A cranking battery is installed on each side,
and a dedicated house battery is installed in the center. Wire leads run through the hull harness to the battery
management panel which is incorporated into the battery access door. 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 80 amp “DC
Mains 1” breaker located on the right 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. The 80 amp “DC Mains 2” breaker controls the
DC panel located in the head compartment. The panel houses the breakers for the Windlass, Marine Head, and
Hardtop Power Supply. The panel is powered by the Starbord 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 290EC 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 290EC 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 receive power from the breakers
in the middle 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 inspection plates in
the motorwell, forward of the engines. The forward bilge pumps can be accesses using the inspection hatches in the
floor of the cabin 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 connections at least annually. To do so, activate the pump by
momentarily lifting the arm on the float switch, then check the operation using the switch pod. When testing, do not
allow the pumps to run dry for more than two to three seconds. Extended dry operation can result in damage to your
pump. Keeping your bilge areas clean can also help extend the life of your pump.
