- It all Adds Up
Enclosed with the QMS package is a length of braided cable
used to provide the electrical connection from the QMS box
to the vehicle. On the interior of the QMS box you will notice
that one of the bolt hole surfaces is bare, shiny aluminum.
Here the terminal lug of the braid attaches to the box, and
here a short jumper connects to the ground connection on
the SG-235 coupler unit.
To provide an effective RF/DC ground on your vehicle:
• make a solid electrical and mechanical connec-
tion to the vehicle body
• ensure the body is grounded to the vehicle chas-
sis (in newer cars with unibody construction, this
is done for you).
Route both the cable and ground strap through the rear
hatch or trunk (the weather sealing strip is usually thick
enough to accommodate them while still sealing out the ele-
ments). Once inside, the cable makes the shortest possible
run to the Powercube (in 500-watt installation) or the trans-
ceiver. Attach the braid to a readily accessible bolt that ties
to the vehicle body:
• Remove the bolt and scrape off a small area of
paint around its hole with a thin strip of sandpa-
per to provide a better electrical connection.
• Use a pencil or ball-point pen to push apart the
strands in the center of the braid to form a hole
through which the bolt may pass (you can trim
the strap and solder on a lug, but this may be
inconvenient or impractical).
• Anchor the strap.
Cover exposed strap: Slip a sleeve of heat-shrink tubing
onto the braided strap along the length that will be directly
exposed to the air and to door-sealing surfaces (8 to 10 inch-
es should suffice). Ground the braided cable to the chassis
using existing bolts and screws, when possible. Prepare the
contact surface by sanding away the paint and primer until
