Inspect HV insulating gloves
NoteCheck gloves for damage prior to each use, Refer to service document TN-15-92-003 R5, for information on inspecting HV gloves, https://service.tesla.com/docs/ServiceBulletins/External/TN/TN-15-92-003_High_Voltage_Awareness_Care_Points_R5.pdf
-
Put on HV insulating gloves and leather over gloves
NoteMake sure to wear Electrical Protective Gloves any time Hioki tester is used
-
Perform Hioki resistance test at each HV joint from HV busbar lead to bolt head
Note2x HV joints, The 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 next step
