Rotating parts and lethal voltage levels are used in operating the FDECU. Be sure
power source is disconnected. Injury or death can occur if connected to power
(1) Shutdown the FDECU per paragraph 2.4 and disconnect it from power source.
(2) Open or remove covers and panels as necessary to access repair area.
Extreme cold can cause electrical wire leads and insulation to become brittle. Do
not disturb electrical wiring that has been exposed to extremely low temperatures.
Damage to electrical wire leads or insulation can result if disturbed under these
(3) If access to a repair requires removal of a component, refer to the replacement procedure for that
component for removal instructions.
(4) Cut and discard tiedown straps as necessary to make the repair.
(5) Tag the wire lead, cable, or harness ends as necessary.
(6) Disconnect wire lead, cable, or harness ends.
(a) Cut off and discard splices or crimp nuts.
(b) Disconnect connectors and cut off pins with housing as necessary.
(c) Cut leads at solder connections then remove and discard insulation sleeving pieces from wire lead
ends and component.
(d) Disconnect wire leads from component.
(7) Loosen strain relief fittings as necessary then note routing and remo ve wire lead, cable, or harness.
(8) Insulating Joints. The preferred method of insulating bare electrical joints is by using insulation sleeving.
To apply, slide a piece of insulation sleeving over the wire lead before making the joint. Make the joint then
slide the insulation sleeving over the joint and shrink in place with heat gun.
(9) Crimping Terminals. If the terminal is not insulated, refer to (8) above. To install the terminal, strip 1/4-1/2
inch (0.6-1.3 cm) of insulation from the end of the wire lead. Insert bare wire lead end into the shank of the
terminal. Crimp the shank securely onto the wire lead.
