  2. Use IPA wipes to clean charge port busbar contact surface of the residual Penetrox.
    Informational PurposesAn informational icon, calling your attention
    Note
    Allow 1 minute dry time for each surface.
  3. Apply 2 drops of Penetrox A-13 about 5mm in diameter to either side of the hole on both leads on the HV connector joints, and then spread the liquid evenly until the contact surface is fully covered.
  4. Install the nuts (x2) that attach the charge port busbar leads to the charge port studs.

    CAUTION
    If excessive force is required to seat busbars, they may have been bent. Inspect for damage and replace if necessary.
    Tip: Use of the following tool(s) is recommended:
    • 10 mm deep socket
    • Flex head ratchet/flex head torque wrench
    • Ratchet/torque wrench
    • Electrical Protective Gloves
  5. Perform Hioki resistance test at each HV joint from the HV busbar lead to the charge port stud.
    Informational PurposesAn informational icon, calling your attention
    Note
    The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.270 mΩ (270 μΩ).
    • If the resistance is greater than 0.270 mΩ (270 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.
    • If the resistance is lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again.
    • If the resistance is repeatedly between 0.00 mΩ and 0.050 mΩ (50 μΩ), Hioki test passed, proceed to the next step.
  6. Install the 3-phase charge port to HV battery busbar safety cap. See Safety Cap - Busbar - Charge Port to HV Battery (3-Phase) (Remove and Replace).
