To replace the cables, install the positive cable first, then the negative cable.
3. Battery Box
The battery box, located in the aft bilge, houses the battery. This box can be accessed via the hatch
located in the aft lounge storage tub. The battery can be installed or removed by loosening the strap
and removing the lid on the battery box. It should always be installed and secured within the battery
box installed on your boat. This will ensure that the battery will not move around while the boat is
underway.
4. Battery Switch
Your vessel is equipped with a battery switch to control the delivery of DC power from the battery.
The battery switch panel is located in the aft lounge storage tub. When you turn the battery switch to
the ON position, power is provided from the battery to the entire boat. To turn on power, rotate the
switch clockwise 90 degrees to the ON position.
Never use an open flame in the battery storage area. Avoid
striking sparks in the battery area.
Always disconnect the battery before doing any work on the
electrical system. Never turn off the battery switches or
disconnect the battery cables while the engines are running.
The bilge pump still draws power from the battery, even if
the switch is set to OFF. This is especially important for the
bilge pump, so that it can operate anytime excess fluid
accumulates in the bilge, which can occur when the boat is
docked and unattended.
Never work on the electrical system while the system is
energized. Never leave the craft unattended with the
electrical system energized.
