Warning

Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional safety information.

    Warning
    HV insulating gloves and leather glove protectors must be worn throughout the remainder of this procedure. Do not remove gloves or protectors until otherwise noted.
  2. Install the A/C compressor fuse to the ancillary bay bus, and then install new nuts (x2) to attach the fuse to the bus.

    Tip: Use of the following tool(s) is recommended:
    • Insulated tools:
      • 8 mm socket
      • Ratchet/torque wrench
  3. Use the Hioki resistance meter to measure the resistance at the HV joint of the A/C compressor fuse and the positive DC busbar.

    CAUTION
    Do not short the side of the probe tip to the edge of the fuse lug.
    Informational PurposesAn informational icon, calling your attention
    Note
    The maximum acceptable resistance is 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
  4. Use the Hioki resistance meter to measure the resistance at the HV joint of the A/C compressor fuse and the electrical harness terminal.

    CAUTION
    Do not short the side of the probe tip to the edge of the nut's captive washer.
    Informational PurposesAn informational icon, calling your attention
    Note
    The maximum acceptable resistance is 0.105 mΩ (105 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
  5. Measure the voltage across the pyrotechninc battery disconnect mount points, and then install the pyrotechnic battery disconnect. See Pyro Disconnect - HV Battery (Remove and Replace).
  6. Install the ancillary bay cover. See Ancillary Bay Cover (Remove and Replace).
    Informational PurposesAn informational icon, calling your attention
    Note
    Before installing the ancillary bay cover, inspect the ancillary bay cover seal and confirm there is no visual damage. If the seal is torn and/or delaminated, replace the ancillary bay cover.
