Care and Maintenance

Battery

A minimum of 650 cold cranking amps is the recommended battery size.

Do not connect

battery cables to

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 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.
