2-11. GENERAL. Instructions in this paragraph provide the general procedures to be followed in the removal, minor
repair, replacement, or installation of components, and testing to the extent allowed at the unit maintenance level as
authorized by the Maintenance Allocation Chart (MAC). When a special procedure is used in the removal, repair, or
installation of a component, that procedure will be detailed in the section covering the component. If no special procedure
is mentioned, then standard maintenance practices will apply.
High voltage is present on this equipment. Do not perform maintenance with
power on. Death or serious injury may result.
General. Most wires on laundry units, whether run individually or in a harness, are marked or numbered.
Be sure to tag any unnumbered wire upon disconnection to ensure proper installation.
Inspection. Inspect insulation for cracks or frayed material. Pay particular attention to wires passing
through holes in the frame or over rough metal edges. If inspection reveals a cut or broken wire, and the
break in the wire is exposed, the wire must be repaired (step (4) below). If the break in the wire is in a
harness, conduit, or inaccessible area, replace the wire (step (5) below).
Testing. Test wires for continuity by disconnecting one end from the component to which it is attached,
making an open circuit. Touch the test probes of a multimeter to each end of the wire. If the meter shows
no indication, the wire is defective and should be repaired or replaced (steps (4) and (5) below).
Repair. Shave the insulation on the wire to expose 1/2 inch (1.27 cm) of bare wire at both ends of the
break. Twist the bare wire together and solder the connection. Cover the break with electrical friction tape.
Be sure to leave no bare wire exposed. If a terminal lug breaks off a wire, replace it with an exact duplicate.
Replacement. Replace a wire by disconnecting it from the component or components to which it is
attached and remove the wire. Connect a new wire to the component or components. If a broken wire is
part of a harness, disconnect the wire at each end and tape the loose ends with electrical tape. Install a
new wire and attach it to the outside of the wiring harness.
