Connections To The Battery - Honda Marine BF8A Owner's Manual

INSTALLATION

Connections to the Battery

Connect the positive (+) battery cable to the positive (+) battery terminal, then
connect the negative (–) battery cable to the negative (–) battery terminal.
The negative (–) battery cable should always be removed from the battery
when connecting or disconnecting the positive (+) battery cable, so tools
cannot cause a short circuit if they touch a grounded part while being used on
the positive (+) battery terminal fitting.
NOTICE
Be careful to avoid connecting the battery in reverse polarity, as that will
damage the battery-charging system in the outboard motor.
