Battery Switch (If Equipped); Battery Selector Switch (If Equipped) - Sea Ray SDX 270 Owner's Manual

4. b s
aTTerY
For safety and convenience, the following items (if
equipped) are not shut off by the battery switches:
Bilge pumps, Sump pumps, Stereo memory
and Battery charger inputs. These items need
constant power to perform their task. This allows
the bilge pump(s) to operate anytime excess fluid
accumulates in the bilge, which can occur when the
boat is docked and unattended.
The battery switch isolates all battery power to the
boat, with the exception of the equipment listed in
the NOTICE above. The battery switch also provides
a positive disconnection of battery to protect against
starter engagement and battery rundown.
If you are leaving the boat for more than two hours
and the boat is not connected to shore power
which is maintaining the batteries, turn the battery
switch(es) to the OFF position.
The battery switch must be turned to On position
for blowers to operate. Turn switch On and operate
blowers for (4) minutes before starting engines.
The switch should never be turned off while the
engine is running to avoid damage to the alternator.
Switching between batteries should also be avoided
while the engine is running unless the switch has
been specially designed for this purpose.

The purpose of the battery selector switch is to keep
one as a spare when the engine is not operating and
the accessory functions, i.e.; stereo, lights, etc., are
being used. If the switch is in the "BOTH" position,
then both batteries are "ON" and being discharged
when the engines are off. This eliminates your spare
and could leave you stranded.
If equipped, the battery selector switch isolates the
boat from the two batteries (with the exception of the
equipment listed in the NOTICE box) and switches
to allow either battery or both batteries to connect
to the boat's electrical systems.
Boats having dual batteries connected using a
4 position battery switch arrangement shall be
operated as follows:
• During start and operation of the boat, the switch
shall be kept in the BOTH position to allow both
batteries to start the engine and allow both
batteries to recharge from the alternator.
• During periods of non-use, the switch shall be
kept in the OFF position.
• During use with the engine off, the switch
shall be placed in the Battery 2 position, which
is the battery that is not connected to engine
clean power.
