gerous, causing severe burns, etc. It con-
tains sulfuric acid. Avoid contact with skin,
eyes, or clothing.
Read the safety and maintenance instruc-
tions which are accompaniment to your

Do not coil and/or loop the battery cable even
if the cable has surplus for routing.
When using a house battery, its capacity is
recommended the same as the main battery
for cranking the engine.
For twin-battery wiring, a battery cable for (–)
terminal has to connect between the house
battery and the main battery.

When one battery is used, connect the large
original red cable and the isolator cable to the
(+) terminal.
The isolator cable has to connect to (+) battery
terminal, because an accidental contact of the
isolator cable to the ground will form a short
circuit and may cause a fire.
If plural batteries are used for multi-engine
installation, all (–) terminals should connect to
the same ground.
Obey the local over-current protection compli-
ance such as ABYC part E-11 for wiring the
battery cables and connecting to a conductor.
* Follow the local rules and/or regulations if your
battery is scrapped.
