Quicksilver 755PH— Electrical Systems
47
1. DC Electrical System
The DC electrical system is powered by two batteries, and 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 SmartCraft
TM
tachometer.
2. Batteries
Refer to your engine owner’s manual for exact batteries requirements. All batteries in a battery bank
should be of the same type, age, and rating.
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 battery boxes, located in the bilge, house the two batteries. These boxes can be accessed by
opening the forward center cockpit hatch. The batteries can be installed or removed by loosening the
strap and removing the lid on the battery box. They should always be installed and secured with the
battery boxes installed on your boat. This will ensure that the batteries will not move around while the
boat is underway.
4. Battery Selector Switch
Your vessel is equipped with a battery switch to control the delivery of DC power from the batteries.
The battery switch is located on the port aft corner of the cockpit behind an access door.
There is a single battery switch that controls two isolated battery banks. When you turn the battery
switch to position “1”, power is provided from the first battery. When you turn the battery switch to
position “2” power is provided from the second battery.
The battery switch also has the ability to combine battery banks at position “1 & 2”. This is the
recommended position for normal operation as it will allow both batteries to be charged when the
engine is running.
The boat may be operated on one battery at a time when using accessories without the engine
running to reserve power in the opposite battery.
NOTE: Never operate or turn off the battery switch when the engine is running as it may cause
damage to electronic components on the boat. Always operate the switch with the engine and
accessories off.
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.
