Installation Procedure — Grounding Strap
Installation Procedure:
GROUNDING A TRUCK SEAT:
1.
Identify any adjustable, shock absorbing seat in the truck cab.
These seats will typically have pivot points, hinges, or other me-
chanical design features that make seat adjustments possible.
2.
Find an existing screw or hole near the back of the seat frame,
close to the cab floor. If a hole or screw does not already exist,
drill a 3/8” hole in the seat frame.
3.
Attach one end of the ground strap to the seat frame bracket
using the lock washer, flat washer and nut provided.
4.
Find and existing hole in the part of the seat frame attached to
the seat cushion above any pivots and adjustments. If a hole or
screw does not already exist, drill a 3/8” hole in the seat frame.
Make sure that there are no interfering pivots, guides, or adjust-
ment mechanisms that could interfere with the ground path
between the seat cushion and the ground strap.
If the seat cush-
ion has a wooden base, attach the strap lug to an existing screw
from the metal bracket directly attached to the wood seat where
the seat fabric is attached to the wood. There must be good
contact between the seat fabric and the ground strap lug.
5.
Use the wire ties provided with the kit and tie off the strap so
that it doesn't interfere with the movement of the seat and is
clear of traffic areas in the cab.
6.
Check the strap for a good ground connection. (see right)
Mount ground strap using sup-
plied hardware or an existing
bolt.
Do not use this ground
point if the seat cushion has a
front pivot.
Mount ground strap using sup-
plied hardware or an existing
bolt.
Bundle excess ground wire using
a wire tie.
Checking for good ground connection along the ground strap:
1.
Turn OFF all accessories, including the dome light, to prevent
other currents from distorting the reading.
2.
Take a multimeter and measure the resistance between the
brackets the ground strap bolts are fastened to.
3.
If the resistance is less than 3Ω, the system is grounded ade-
quately. If the resistance is still greater than 3Ω, check for
proper metal to metal contact on both ends of the grounding
strap. Clean any paint, dirt, or oxidation that may block the
grounding point. If the resistance remains above 3Ω, attach
the ground strap to a different point and repeat the process
until resistance is below 3Ω.
