BATTERY LAYOUT AND MANAGEMENT
The 250 DC is equipped with three batteries, which are located in the aft rigging compart-
ments. They can be reached using the access hatches located on the aft transom wall beneath
the livewell and fishbox. A cranking battery is installed on each side, and a dedicated house bat-
tery is installed in the starboard compartment. Wire leads are run to the battery management
panel located behind the access hatch in the center of the aft transom wall. See Chapter 3 for
information regarding the operation of this panel. The engine cranking leads are connected
directly to the battery management panel. The negative engine leads are connected to the com-
mon battery ground using the cranking battery on their respective side (see diagram below).
The house battery provides the power for all your DC accessories. The main lead runs to the
“HOUSE” switch on the battery management panel. From there current is routed to the console
through the 50 amp “DC Main” 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 (see diagram below).
For a detailed drawing of the battery management panel connections, see the diagram on
page 12 of this chapter.
