TM 9-2350-274-BD COMMUNICATIONS SYSTEM 11-14. ISOLATION OF NON-ESSENTAIL SYSTEMS (GENERAL) General Information: This procedure lists general guidelines for the isolation of non-essential systems. Limitations: ● Varies depending on which system is isolated. Personnel/Time Required: ● 1 soldier ● 5-30 minutes Materials/Tools: ● Crimp-on end caps, electrical tape or other insulating material. Procedural Steps: 1. Insulate/isolate non-essential wiring or cabling with crimp-on end caps, tape, or any other insulating material. Secure wires to some structure and tag them for rapid identification. 2. Any intercom control box can be considered non-essential if one is willing to operate without it. Disconnect the cable leading to that particular control box at AM-1780 and consider using field expedient means for intercom. Also, consider switching control boxes and/or cables within the vehicle to provide intercom at the desired points. For repairs of this type, existing cabling can be rerouted if the original cables have been ■ damaged. 3. Record the BDAR action taken. When the mission is complete, as soon as practicable, repair vehicle using standard maintenance procedures. Change 3 11-17
