Inspect HV insulating gloves
注Check gloves for damage prior to use, Refer to service document TN-15-92-003 R1, for information on inspecting HV gloves. https://service.teslamotors.com/protected-doc/ServiceBulletins/External/TN/TN-15-92-003_High_Voltage_Awareness_Care_Points_R4.pdf
-
Put on HV insulating gloves and leather over gloves
注Make sure to wear Electrical Protective Gloves any time Hioki tester is used
-
Install amp clamp to RDU HV harness
注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 requiredIf current < 0.5A, Ok to disconnect and check voltage at HV plug on the battery side.
-
Release RDU HV harness from HV battery
