Quicksilver 905WE — Electrical Systems
1. DC Electrical System
The standard DC electrical system is powered by two batteries, while the twin engine option consists
of three. These batteries are kept charged by the engine driven alternator or by the battery charger
when connected to AC power. The battery voltage is indicated by the voltmeter screen located on the
TM
SmartCraft
tachometer, or on the optional GPS with Vessel Link.
2. Batteries
Quicksilver® recommends AGM type starting or a deep cycle battery for you boat. The battery must
meet the minimum capacity required by the engine manufacturer. Refer to your engine owner's
manual for exact battery requirements.
To remove the battery cables:
1. Turn off all items drawing power from the battery.
2. Turn the battery switches to the OFF position.
3. Remove the negative cable first, then the positive cable.
To replace the cables, install the positive cable first, then the negative cable.
3. Battery Boxes
The batteries are located in the aft bilge and can be accessed through the cockpit floor storage hatch.
They can be installed or removed by loosening the strap and removing the lid on the battery box. The
batteries should always be installed and secured within the battery boxes on your boat. This will
ensure that the battery will not move around while the boat is underway.
Never use an open flame in the battery storage area. Avoid
striking sparks in the battery area.
4. Battery Selector Switches
Your vessel is equipped with battery switches to control the delivery of DC power from the batteries.
The battery switches are located on the starboard side of the cockpit behind an access door. The
number of engines and options on your boat determines the number and type of battery switches.
The bilge pumps still draw power from the batteries, even if
the switches are set to OFF. This is especially important for
the bilge pumps, so that they can operate anytime excess
fluid accumulates in the bilge, which can occur when the
boat is docked and unattended.
Single Engine Boat
On a single engine installation, there is one battery switch that controls two battery banks. When you
turn the battery switch counterclockwise 90 degrees from the off position, power is provided to the
entire boat by battery #1. When you rotate the battery switch clockwise 90 degrees from the off
position, power is provided to the entire boat by battery #2. Rotating the battery switch clockwise 180
degrees from the off position allows you to combine the batteries together providing power to the
entire boat.
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.
Never work on the electrical system while the system is
energized. Never leave the craft unattended with the
electrical system energized.
