• "OFF" - you will
have no power to
the engine.
Be sure engine is stopped
before switching to
"OFF".
CAUTION
!
You MUST stop the engine before moving the
switch to the "OFF" position.
• "1+2" - you will have
power from both batteries
at the same time. This
parallels the batteries to
assist you, if necessary,
in starting the engine.
Once the engine is
started, the battery switch should be
switched from the "ALL" setting, and
set to charge either battery.

DO NOT operate the boat with batteries in "1+2"
once the engine is started or serious engine
electrical damage may result.
Use the "1+2" position only if both batteries are
near the same voltage. If one battery is strong
and the other weak, high current could cause
battery damage.

• "2" - you will have
When the engine is shut down or not providing a
charge, the system allows for isolation of the number
OFF
"1" battery. This will allow you to run all the boats
functions without affecting the number "2" battery.

In the event the number "1" battery discharges
completely, you will still be able to start the engine by
1+2
turning the battery switch to the number "2" position.
This accesses the charged battery for engine starting.
After the engine starts, return to the discharged
battery (number "1" position).
The Bilge pump, stereo memory and clean power
for the optional DTS system still draw power
OFF
from battery #1, even if the switch is set to
"OFF". For this reason it is recommended that
