TYPICAL REMOTE BATTERY SWITCH
As part of the battery management system remote battery
switches are located in the engine room.
A remote battery switch is wired between each engine
and the "on-off " universal battery switches located at the
battery management system panel. See the illustration.
Their purpose is to break up the long battery cable runs
from the batteries to the management center panel. Also,
they offer a shorter run from the battery to the starter
motor. In addition, the remote battery switch from the bilge
(sump) provides an avenue to shut down the battery system
during engine or sump routine maintenance functions.

If the remote battery system fails the skipper can turn on
the remote battery switch manually through the manual
override switch located on each remote battery switch
which will generate power for engine starting.
Each remote battery switch provides a continuous rating
of 300 amps DC and a cranking rating of 1250 amps DC.
Both remote battery switches are "in line" between each
battery and the engine.
REMOTE BATTERY SWITCH OPERATION
Under normal conditions with the vessel charging sys-
tem working properly each remote battery switch should
show a lighted LED on the faceplate. When the remote-
battery switch is in the "OFF" position the LED is not
lighted. The manual override switch should be located in
the AUTO position. Read and understand the notice be-
low.
