(b)
Split the ends of cable into manageable strands and join the two ends by twisting like strands
together.
(c)
Bend the twisted end parallel to the cable and insulate with tape.
(3) Option 3: Clamp, Splicing.
(a)
Remove one inch in insulation from each end
(b)
Fan out the strands on each end.
(c)
Ram the two ends together as far as possible, so that the strands intermesh (figure 7-9).
Figure 7-9. Splicing Cable with Clamp.
(d)
Solder the intermeshed wires together. If a soldering iron is not available, the two intermeshed
ends may be secured with a screw clamp, cable clamp, or safety wire.
(e)
Insulate with tape.
Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the generator using
standard maintenance procedures.
Section IV. ELECTRICAL MOTORS
7-13. General. Repair on electric motors should be restricted to relays, solenoids and brushes. Damage to casings and
winding cannot be expediently repaired.
7-14. Brush, Electrical, Alternator/Starter-Motor, Worn. Many electrical motors use a carbon composition brush to
transfer electrical energy to or from the armature commutators. The transfer of energy creates an electrical arc which
will burn the brushes. Arcing the normal friction will cause the brushes to become worn and inefficient for electrical
power transfer. The brushes can be substituted with the carbon core from a BA30 or BA31 battery. Care must be taken
when opening the battery; the contents are corrosive. Brush retaining springs can be used to transfer the energy or to
hold the old brush wires in place.
