      J100 Proper Power Cable Fastening

      Please take your time when doing this procedure, we have attached walkthrough videos at the bottom!

      J100 Proper Power Cable Fastening


      This guide will teach you how to properly secure the flight motor/esc power cables to the arms.


      Why: Properly fastening power cables can help solve 3 potential issues caused by high amperage and heat.

      1. Make the connection of the cable to the bullet connectors more stable and less prone to high frequency vibration. This vibration combined with high cable heat due to prolonged high current can cause the wire strands to be severed at the base of the bullet connector. This reduces wire diameter and creates excessive heating resulting in a complete separation of the wire at the base of the bullet connector. 
      2. High vibration can cause bullet connectors to wear through the heat shrink and fabric tape if it rubs against the arm or motor mount. This can cause a short circuit. 
      3. From the factory, EAVision uses zip ties to fasten cable to the arm. The zip ties may wear through the cable insulation.

      Process for Proper Cable Fastening


      1. Remove zip ties if they are present.
      2. Ensure the adhesive foam pad is installed behind the cable.
        1. If it is not installed and you do not have adhesive foam you can use multiple layers of fabric tape. Recommend 5 layers.
        2. This Drone does not have adhesive foam.
      1. Ensure that the power cables are individually wrapped with fabric tape.
        1. Only the section of the cable that will will be fastened to the arm needs to be wrapped
        2. The above picture shows cable that are wrapped 
      1. Check if the bullet connectors are the old style or new style.
        1. You can check by feeling the part of the cable that has a larger diameter (this is where the bullet connectors are located). If you feel thin part of the connector that is larger in diameter and sharply protrudes out then that is the old style.
        2. Consider replacing the entire cable harness with a new style if available. 
        3. This picture show the old style connectors with the thin ridge, it is difficult to see in picture. 

      1. Apply 5 layers of fabric tape above the cables on the underside of the motor mount and make sure it covers the motor bolts.
        1. This will remove pressure on the cables as they will be pressed firmly against this area.

      2. Ensure there is enough slack in the cables to allow one side of the bullet connector to align with the gap between the motor and ESC.
        1. If not then carefully cut back the fabric tape around the cable harness coming out the end of the arm.
        3. Cut Here if more slack is needed

       

      1. Arrange the cables such that the power cables are on the top and bottom with the signal cable in the middle.
      2. Tape the cables between the motor and ESC
        1. Attach tape roll to the bottom of the arm
          1. Above picture shows this
        2. Push the cables up against the motor mount and back toward the ESC so that that part of the bullet connector will be under the tape
        3. Begin rolling tape around the arm and over the cables ensuring the press the cables firmly against the arm.
        4. Wrap 4 times leaving the end of the tape on the bottom of the arm.
      3. Tape the cables diagonally 
        1. Attach tape roll to the bottom of the arm and end of the motor mount closest to the ESC.
        2. Press the cables firmly against the arm up against the motor mount
        3. Wrap the tape diagonally across the cable and over the end of the arm just below the bolt holes for the pad.
        4. Wrap 4 time leaving the end of the tape on the bottom of the arm.
      4. For front arms, tape the cables diagonally in the opposite direction
        1. Attach the tape roll to the bottom of the motor mount in the center on a ridge
        2. Wrap diagonally between the motor and ESC.
        3. Wrap 4 time leaving the end of the tape on the bottom of the arm.
      5. Check the cables and connectors
        1. Try to move the cables in each direction.
        2. If the connector part of the cable is able to wiggle and be moved freely in any direction then apply tape with more pressure. 
        3. Ensure that the cables are all pressed against each other, pressed against the arm, and pressed up against the motor mount while you are wrapping tape.
