6.4 Parallel Switch & Dead Batteries
Dead Engine Starting Battery
In the event of a dead engine battery, the engine
starting batteries or engine and house batteries
can be placed in a temporary parallel configura -
tion. This allows you to start an engine from two
battery banks combined.
To connect the engine batteries in parallel to start
the engines, turn both engine battery switches
to the COMBINED BATTERIES position and start
each engine. Once the engines have started and
systems have stabilized, turn both switches to the
ON position to isolate the circuits.
To connect the port engine battery in parallel with
the house batteries to start the engine, turn the
house and port engine battery switches to the
COMBINED BATTERIES position and start the en-
gine. Once the engine has started and systems
have stabilized, turn both switches to the ON
position, to isolate the circuits.
To connect the starboard engine battery in parallel
with the house batteries to start the engine, turn
the house and starboard engine battery switches
to the COMBINED BATTERIES position and start
Part Engine & House Battery Switches in Parallel (COMBINED BATTERIES) Position
the engine. Once the engine has started and sys-
tems have stabilized, turn both switches to the ON
position to isolate the circuits.
Dead House Batteries
In the event of dead house batteries, there are a
couple options:
• If at the dock, simply plug in the shore power
and operate the battery charger to recharge
the house batteries.
• If at sea, start one or both engines. Once an
engine is running, the DVSR circuit will sense
low voltage in the house battery bank and
direct available current to charge the house
batteries. Operating both engines will recharge
the house batteries much quicker. The batter-
ies will continue to be charged until the engine
or engines are shutdown, isolating the house
batteries from the engine batteries.
Notice:
If a battery is fully discharged/dead for a
lengthy period, it may become permanently
damaged and will not be able to hold a
charge.
