STANDARD FEATURES
BATTERY LAYOUT AND MANAGEMENT
The 270 ECS is equipped with three batteries, which are located in the port seatbox They
can be reached using the access hatch located aft of the port seat. Two cranking batteries and a
dedicated house battery is installed in the this compartment. Wire leads are run to the battery
management panel located on the forward wall of the seatbox. See Chapter 3 for information
regarding the operation of this panel. The engine cranking leads run aft from the management
panel to the positive stud on the alternator of each engine. The negative engine leads run from
the alternator to negative buss bar located on the transom wall, and then to the common
ground through a single lead running forward.
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 15 of this chapter.
