DC Power Cable Installation

This MaxTrac radio must be operated only in negative-ground electrical systems.
Reverse polarity does not damage the radio; however, radio protection circuits
cause the cable fuse to open. Check the vehicle ground polarity before you begin
installation to prevent wasted time and effort.
The 10-foot dc power cable shipped with the radio is long enough for installation
in most vehicles. Begin the power cable installation in the following manner:
(1) Determine a routing plan for the power cable with reference to where the
radio is to be mounted.
(2) Locate an existing hole with a grommet in the vehicle fire wall, or drill a 3/8"
access hole at the location for passing the power cable into the engine
compartment. Install a grommet with 1/4" internal diameter in the access
hole to avoid damage to the cable.
CAUTION: A high degree of care should be exercised not to damage any
existing vehicle wires.
(3) From inside the vehicle, feed the red and black leads (without lugs attached)
through the access hole and into the engine compartment. See Figure 1.
