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.
