If, however, the wire sheath disappears into a lump of resin:
Snip the sheath with a pair of fine side-cutters as close to the resin
lump as possible.
Cut back the sheath by about 1/4" to expose the ends of the two wires
Remove any insulation from the exposed ends of the two wires.
Twist the ends of the wires together and solder them together.
Now fit a layer of heat-shrink insulation sleeve, preferably
adhesive-lined, so as to insulate the ends of the wires from everything
Poke the wires back into the space between the drive-end end-piece
and the bobbin, and if possible tuck them in so that there is no risk of
them flying out again as the armature rotates.
That completes the 'quick snip.'
If it turned out that there there wasn't enough room to perform
all of the above steps, then you will now need to disassemble the armature
as described in the 'complete works'
