Garage Gurus | Insulation Testing on Hybrid Vehicles

Автокөліктер мен көлік құралдары

With its high-voltage battery, servicing a hybrid vehicle brings new procedures that have to be followed. To ensure that no voltage is leaking from a high-voltage wire or lead, you should do an isolation test. Follow along as Master Trainer Mark Kenyon of Garage Gurus demonstrates how to perform this important test.
Using an insulation testing meter, Mark explains that by inducing voltage from the meter, you’re able to determine if there is any voltage leaking. Check out the other Garage Gurus videos on working with hybrid vehicles: Service Disconnect and Live-Dead-Live High-Voltage Verification Test.

    I have in the shop a 2016 Hyundai Sonata Hybrid with DTC POAA6 EV battery insolación fault. And I am having difficulties to figure out where this insulation fault actually comes from. Dealer told customer that they need a transmission but I’m not to sure about it it’s only $14,000 USD for a new trans.

    Do we have to take out the MSD to begin with this test ? Also should the 12v auxiliary battery cutoff switch be turned off ?? Really need some guidance

    So you just pulled the service plug? You left the cable connected to the battery?

    I think I understood the test? after removing the safety switch did you tested the actual hybrid battery? To make sure it’s not grounded to the chases ground?

    He probably only tested the *cables* coming from the batteries. The battery contactors are probably closed, so the battery cannot be measured easily this way. See also the WeberAuto channel "Megohmmeter - Loss of Isolation Diagnostics".
