Chaparral 2009 Signature 250, Owner'S/Operator'S Manual

Page: 44 / 148

Batteries
The batteries installed in your boat by your Chaparral dealer supply
your boat with DC current for lights, engine starting or generator,
and accessories. When the engine is running, the alternator sup-
plies the power needed to keep the batteries charged. Lights and
accessories draw power from the batteries.
Battery Selector Switch
The battery selector switch is in the engine compartment or stern area
of your boat. Some models will have more than one switch. Leave
switch on while motor is running or damage will occur to alternator.
Three Selector Switches with Two Batteries and
Single Engine
Models: Signature 270 and 250
Each of the three battery switches have two positions:
All Switches Off
Power supplied to automatic bilge pump, CO detector (if so
equipped), stereo memory, and corrosion protection system (if
so equipped).
#1 Battery Switch ON
Use only Main Engine battery.
#2 Battery Switch ON
Use only House battery.
Recommended settings are as follows:
1. All Switches Off
When boat is not in use or power is not required, turn all
switches to OFF. The only power supplied at this setting is
the automatic bilge pumps, carbon monoxide detector (if
equipped), stereo memory and high water alarm.
2. #1 Battery Switch ON
To start the engine, place switch in ON position. With this
setting, power will now be supplied to your engine.
3. #2 Battery Switch ON
For cabin or accessory power, place the switch in the ON
position. Power will now be supplied to your boat from the
House battery.
Note: Chaparral does not recommend leaving all three
switches on when the engine is off. This will drain both batter-
ies and you will not have a starting battery.
4. #1 Battery, #2 Battery and Parallel Switches ON
If both batteries are low, you still have the option of starting
the engine by combining the output from both batteries.
Note: When recharging a low battery, be sure to run the engine
for a sufficient amount of time to fully recharge the battery.
Note: Chaparral does not recommend any other settings than
mentioned because of possible damage to batteries or engine
alternator.
Note: Chaparral recommends leaving the parallel switch in
OFF position unless starting engine.
