3 Open the ground box lid (1) and disconnect the
wire harness going to the display controller
(DISCON).
4 Remove the DISCON door from the back by
loosening the four Torx head screws (8) and
remove the two ribbon cables (6) connecting
the ground box overlay to the DISCON.
Note the orientation of the cables for reassembly.
5 Remove the DISCON from the ground control
box lid by removing the five hex nuts and
washers (4, 5). Discard the nuts and washers.
Note the lanyard attachment point for reassembly.
6 Remove the old DISCON gasket (2) from the
ground box lid and clean the lid surface from
any dirt, oil or old adhesive residue. Use a 99%
solution of isopropyl alcohol to clean the
surface. Allow the surface to completely dry.
Note: Both the ground box lid and new gasket must
be 70° F / 21° C or higher at the time of application.
Application of the new gasket at lower temperatures
is not recommended.
7 Peel the adhesive protective film from the back
of the new gasket. Carefully line up the new
gasket over the ground box lid, making sure
the cutouts for the LCD screen, ribbon cables
and mounting studs are centered and lining up
with the gasket. Apply the new gasket to the
ground box lid and work from the center out to
eliminate air bubbles and make sure all the
gasket edges are securely fixed.
Note: Once applied it is not recommended to lift the
gasket and attempt to reposition it.
Install the new DISCON onto the ground box lid and
fasten it using the new hex nuts and washers. All
five fastening points must be used. Attach the
DISCON door's lanyard to the DISCON's mounting
stud.
