TM 9-2350-358-BD 3-6. BRACKET (WELDED), BROKEN Equipment mounting brackets welded to the hull sometimes break due to vibration or collision with obstacles. Brackets are needed to mount components and devices in locations or positions where they can be used to perform their required function. Mount bracket into place and secure by welding. Limitations: None Personnel/Time Required: • 2 soldiers • 1.0 hour Materials/Tools: • Rod, welding (item 51, Appendix C) • Welding equipment Procedural Steps: 1. Set broken portions of bracket in original position. 2. Weld bracket in place. 3. Elongate holes or slots in bracket to compensate for misalignment. 4. Record BDAR action taken. When mission is complete, as soon as practical, repair the equipment/system using standard maintenance procedures. SECTION III. WIRING HARNESSES 3-7. GENERAL Wiring harnesses are normally replaced when extensive damage occurs. Because of improvements of different configurations, replacement harnesses from other vehicles of the same vehicle family may use some different style connectors. Try to obtain harnesses from an identical model if necessary, connectors can be exchanged with the damaged harness. The same procedure is followed to change a complete connector or splice a complete harness. If a wire is damaged, but the fault cannot be located, it should be replaced with a jumper wire. 3-8. WIRING HARNESS, DAMAGED Wiring harness repairs are generally accomplished using a series of single wire splices. Establishing circuit continuity in a bundle of wires is difficult because individual wires are not color-coded. Wires must be identified before they are connected. Most essential electrical functions can be rapidly restored by using jumper wires. Option 1 Limitations: None Personnel/Time Required: • 1 soldier • 0.5 hour 3-3
