Note
Connecting to an accessory fuse
prevents the unit from being left
on accidentally, and also
permits operating the unit
without running the engine.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.
Note
Before installing the CB radio,
visually check the vehicle’s
battery connection to
determine which terminal,
positive or negative, is
grounded (positive is the larger
of the two) to the engine block
(or chassis).
A negatively grounded vehicle
has its negative lead grounded
to the chassis.
In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
Connect the black lead to the negative side
of the vehicle. This is usually the chassis. Any
convenient location with a good electrical
contact (remove paint) may be used.
