WIRE REPLACEMENT - CONTINUED
5.
Slide new lengths of heat shrinkable tubing (item 23, appendix C) onto wire ends if desired. Always use heat
shrinkable tubing around wire splices, or wrap them with electrical tape (item 30, appendix C).
6.
Connect terminal lugs to wire by soldering or crimping as necessary. Make sure that connections are tight.
7.
To splice two wires together, twist and tin end strands of each wire separately. After allowing tinned ends to
cool, twist both together, and reheat to fuse ends together.
8.
If heat shrinkable tubing is used, shrink it around connections.
ELECTRICAL GROUND POINTS
Many electrical problems are the result of poor ground connections. You can make sure that ground connections are good
by doing the following:
1.
Remove hardware connecting ground cable terminal lug to ground point.
2.
Clean ground cable terminal lug to ground point mounting hardware.
3.
Remove any rust with wire brush and emery cloth.
4.
Look for cracks, loose terminal lugs, and stripped threads. Replace any defective parts.
5.
Install hardware connecting ground cable terminal lug to ground point.
TEFLON TAPE
New Teflon tape (item 32, appendix C) should be used to keep connections from leaking whenever you are connecting
fuel, oil, and hydraulic system lines and fittings as follows:
1.
Be sure threads are clean and dry.
2.
Start tape one or two threads from small or leading edge of fitting, joining tape together with an overlap of
about 1/8-inch (3.18-mm) for fittings with fine threads. For fittings with course threads, tape should be wrapped
around threads two or three times.
3.
Wrap tape tightly in same direction as you would tighten a nut. Tape must be pressed into threads without
cutting or ripping.
CAUTION
Do not go over specified torque or use power tools to tighten Teflon-taped fittings. Overtightening could
damage fitting threads and cause connection to leak.
4.
Use hand tools to tighten and torque fittings to specified torque.
