11. Inspect all components and replace damaged, aged, or questionable parts.
To reassemble, perform this procedure in reverse. Note the following:
• The reflectors are properly seated to the PCBs.
• J5 is +12V, J4 is ground. Do not reverse polarity.
• Dress the PS-DS harness so that it is not pinched when the extrusion is installed.
• Reseal the harness and wire exits with RTV before installing extrusion.
• Do not cut new threads. Back the screw counter-clockwise until you feel the screw
click into the existing thread, and then tighten. Start the ground screw with the
lockwasher first. Do not overtighten.
• Tighten the mounting feet according to the mounting feet kit instructions.
