HEAT SHRINKABLE TUBING
Heat shrinkable tubing (item 15, Appendix C) Is used to Insulate soldered and crimped electrical connections as follows:
1. Cut desired length of new tubing twice the diameter of the connection to be covered.
2. Slide tubing onto wire and out of the way before making connection.
3. After making electrical connections, slide tubing Into place over it.
Do not touch heat shrinkable tubing for at least 30 seconds after heating. Hot tubing can burn you.
4. Hold heat gun 4 to 5 inches away from tubing and apply heat for about 30 seconds. Stop applying heat as soon as
tubing forms to shape of connection.
WIRE TERMINAL AND CONNECTOR REPLACEMENT
Replace wire terminals and connectors as follows:
1. Cut off damaged terminal or connector with diagonal-cutting pliers.
2. Slide new length of heat shrinkable tubing (item 15, Appendix C) onto wire if desired.
3. Using wire stripper, strip enough insulation from wire to allow bare wire to go all the way into hole In terminal or
4. Select proper terminal or connector for wire size and terminal stud or other mating connector.
5. Insert bare end of wire all the way into hole in terminal or connector.
6. Crimp or solder terminal or connector to wire. Make sure that connection is tight.
7. If heat shrinkable tubing is used, shrink it around connection.
Although battery ground cable must be connected to test electrical circuit voltage, disconnect battery
ground cable before doing resistance tests or replacing parts. This will keep you from getting shocked and
prevent damage to parts and equipment.
Replace damaged electrical wires as follows:
1. If terminals or connections of wire to be replaced are covered with heat shrinkable tubing, cut off using sharp knife.
