Battery
A minimum of 650 cold cranking amps is the recommended battery size for 2011 models.
Do not connect

incorrect Terminal
Post ±. Doing so
may cause a
reverse polarity
current to run
through your electrical system
and cause damage to your engine
and other electrical components.
Damage done to your boat due to
incorrect terminal placement is
not covered under your Axis
warranty.
Check your battery terminals frequently
for corrosion and tightness. Clean terminals
with a baking soda and water solution and a
wire brush. Also, check the fluid levels in
the cells. Usually, a level approximately 1/4 to 1/2 in. above the plates is sufficient. If
needed, fill with distilled water. Some batteries are sealed and this process is not
necessary. Read directions when applicable.
Electrical Distribution-Battery Switches:
All main engine battery cables for 2011 are the larger, 2/0 size. Always use a
Starter/Cranking battery, minimum size of 650 Cold Cranking Amps on the big cable.
This is the starter or cranking circuit.
There are also a set of smaller #2 AWG battery cables with the positive/red coming from
an 80-AMP main circuit breaker (on the smaller boats, a #6 AWG cable and a 60-AMP
main breaker). These smaller cables are the feeder circuit to the boats breakers and
switches. These are referred as the House circuit.
#1 on a Single Battery System:
Both the cranking circuit and the house circuit are connected to the same battery. One
battery running everything all connected together.
#2 on a Dual Battery System:
With a battery selector switch commonly called a "battery isolator switch"; both the
house and the cranking circuits are always connected together at the selector switch. You
have the ability to switch between 1-2 or all of the batteries to connect to the house and
starter circuits. The current to charge the batteries, will come from the starter circuit,
flowing from the engine alternator to the battery switch common terminal. When the
engine is running you will have the ability to charge ether #1 or #2 or both of the batteries
at the same time. When the engine is off, you will pull current for both the house and
cranking circuit on which ever battery you have selected or both batteries.
