    Note
    Verify meter is zeroed out before performing measurement, Measure single cable. Verify ammeter is installed in correct direction. If current > 0.5A do not proceed with disconnecting HV connector. In this case, start vehicle electrical isolation again to make sure that all was properly shut down. Escalate for assistance as required if current < 0.5A, OK to disconnect and check voltage at HV plug on battery side.
  18. Release the RDU HV harness from the HV battery.
  19. Verify that there is no high voltage at the RDU HV header.
