To repair broken or cut wires that are othewise
sound, the mating ends can be stripped and
spliced.
A commercial butt splice can be crimped onto the
ends to join them, or a wire splice can be made.
A wire splice is made by stripping one 1-1/4 inch of
insolation from the wire ends, holding the ends
parallel and facing opposite directions, then twist-
ing each end around the other wire at least three
turns.
Solder and apply insulation.
To install a terminal on end of a wire, strip 1/4 - 1/2
inch of insulation from the end of the wire.
Apply a 1-inch piece of heat-shrink tubing (if the
terminals are of the uninsulated type), and insert
wire-end into the shank of the terminal.
Crimp the shank.
Install heat-shrink tubing if necessary.
The preferred method of insulating electrical joints
is by the use of heat-shrink tubing.
To apply, cut a piece of heat-shrink tubing of suit-
able diameter to a 1-inch length for covering joints
at terminals or connectors, or to a length about
1/2-inch longer than the joint to be insulated.
Slide the tubing over the wire before making the
joint.
After the joint is rode, elide the tubing over the
joint and shrink in place with moderate heat.
Wire connections must be made mechanically
sound before they are soldered.
Solder alone does not provide sufficient strength to
prevent breakage.
Joining surfaces of connections to be soldered
must be dean and bright.
