    注
    2x nuts, 8mm, 2.5 Nm
  19. Remove the electrical harness terminal from the mounting stud and move aside.
  20. Use the fuse puller to remove the power conversion system fuse from the mounting studs.

安装

  1. Perform a zero adjust of the Hioki resistance meter in preparation to measure resistances later in this procedure. See 电阻表（零点调节）.
  2. Use the fuse puller to install the power conversion system fuse onro the mounting studs.
  3. Install the electrical harness terminal onto the mounting stud.
  4. Install the nuts (x2) that attach the power conversion fuse to the mounting studs.
    2.5 Nm (1.8 lbs-ft)
  5. Use the Hioki resistance meter to measure the resistance at the HV joint of the power conversion system fuse and the positive DC busbar.

    警告
    Do not short the side of the probe tip to the edge of the fuse lug.
    Informational PurposesAn informational icon, calling your attention
    注
    The resistance must be less than 0.145 mΩ (145 μΩ). There is too much resistance in the High Voltage joint. Remove the fastener, clean areas with isopropyl alcohol, install fastener back and test again.
  6. Use the Hioki resistance meter to measure the resistance at the HV joint of the power conversion system fuse and the electrical harness terminal.
