Wiring.

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 in accessible area, replace the wire (step (5) below).
Testing. Test wires for continuity by disconnecting one end from the components 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 is 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.
