TM 9-2350-358-BD 3-12. HEAVY DUTY CABLES, BROKEN - CONTINUED Procedural Steps: 1. Turn off MASTER power switch. 2. Cut and splice corresponding wires (para 3-10). 3. Wrap insulating tape around first splice and leave hanging. 4. Cut and splice next corresponding wire, approximately 1 inch from first splice. 5. Wrap tape around second splice without breaking tape from first splice. 6. Repeat steps 2-5 until all splices are complete. 7. Record BDAR action taken. When mission is complete, as soon as practical, repair the equipment/system using standard maintenance procedures. 3-13. SHIELDED CABLES, DAMAGED Some high-voltage or high-current electrical circuits are shielded to prevent the circuit from inducing a current in a parallel circuit. The shield is connected to a ground which will stop current from escaping or entering the conductor from any source other than its own circuit. Shielded cables should be replaced. Repairs are possible if replacement cables are not available. Splicing wires is a quick fix for damaged shielded wires. Option 1 Limitations: Radio Frequency Interference (RFI) may be induced. Personnel/Time Required: • 1 soldier • 0.5 hour Materials/Tools: • Solder, lead-tin alloy (item 58, Appendix C) • Tape, insulation, electrical (item 63, Appendix C) • Wire, fuze (item 79, Appendix C) 3-15
