  18. Use the Hioki resistance meter to measure the resistance between the charge port busbar connector lead and the DC input HV header bolt head.
    Informational PurposesAn informational icon, calling your attention
    Note
    The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ). If the measured resistance is above 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.
    Informational PurposesAn informational icon, calling your attention
    Note
    If the resistance is lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again. If after 4 attempts the resistance is consistently lower than 0.050 mΩ (50 μΩ), the test has passed; continue to the next step.
