-
Perform Hioki impedance test at the positive and the negative HV joints of the fast charge busbar DC link side.
NotaThe resistance of the positive HV joint should be 25 𝜇Ω or less, and the resistance of the negative HV joint should be 40 𝜇Ω or less.
-
Install the ancillary bay left terminals cover.
Nota2x tabs, 1x datum
-
Install the harness clips (x2) to the fast charge contactor cover.
-
Connect the LV fast charge connector.
-
Attach the locking tab to install the A/C filter harness to the fast charge contactor cover.
-
Connect the connector that attaches the power conversion system to the A/C harness.
NotaPush the connector downward, and then push the locking tab downward to install the connector. Make sure the connector is fully seated.
-
Install the ancillary bay harness clip around the negative pack contactor area.
-
Install the pyrotechnic battery disconnect. See Pyro Disconnect - HV Battery (Remove and Replace).
NotaStop this step after inspecting the ancillary bay walls and cover seal for damage.
-
Position the ancillary bay cover to the HV battery.
NotaEnsure all accessible insulators are present.
-
Use IPA wipes to clean the HV connector contact surface and the busbar HV connector contact surface of the residual Penetrox.
NotaAllow 1 minute dry time for each surface. The new busbar comes with the penetrox applied to the HV connector. It is necessary to clean the HV connector during the re-use of the busbar.
- 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.
-
Position the busbar kit connector and lower it onto the HV header.
NotaShift the rear end of the busbar assembly upward to help ease installation. If excessive force is required to seat the busbar, they may have been bent. Inspect for damage and replace if necessary.
-
Install the A/C charge port inlet harness clip.
-
Install the bolts (x2) that attach the charge port busbar kit to the HV header.

-
Perform Hioki resistance test at each HV joint from the HV busbar lead to the bolt head.
NotaThe acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ).
- If the resistance is greater than 0.195 mΩ (195 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.
-
Install the bolt that attaches the busbar cover access door.
