HYDRAULIC CONTROL MODULE JUMPER WIRES (CONT)
Remove screw (8) and lockwasher (9) and remove wire (5) from steering control manifold (10).
Remove nut (11) and tag and disconnect wire (12) from pressure switch (7).
Soldering fumes are toxic. Avoid breathing thee fumes. Work in a well-ventilated
area or injury to personnel may result.
Rosin core solder contains flux which is corrosive. All soldered connections must
be cleaned of all flux residue or damage to equipment may result.
Using a soldering gun, unsolder wires (12 and 13) from steering pressure indicator light (14).
Using semitrailer electrical schematic (figure FO-1) as a guide, tag and disconnect socket connector (15) from W3
Inspect hydraulic control module jumper wires for missing or unreadable wire markers. If defective, apply new
markings or replace wire markers. Use semitrailer electrical schematic (figure FO-1) as a guide for proper wire
Inspect hydraulic control module jumper wires for frayed or broken wires and loose terminal lugs. If defects exist,
use electrical repair kit and replace defective terminal lugs or entire jumper wire assembly.
Refer to appendix F and, using electrical repair kit and measuring tape, fabricate new hydraulic control module
jumper wires as required.
Using wire stripper, strip wires to designated length to allow for terminals to be installed.
Using electrical repair kit, crimp terminal lugs onto fabricated jumper wires as required.
Aline ground lead of jumper wire (5) with steering control manifold (10) and secure in place by loosely installing
lockwasher (9) and screw (8).
