Hello guys,

I've read that there are some experts on Hyundai/Kia hybrids on this forum but I can't remember their user names.
The error code is P0A78 subcode 103 wich they claim is related to either the invertor(which i replaced) or with motor insulation. Can someone please say what motor insulation refers to and how should one test that?

I don't know to whom you have been before that they didn't have fees for the diagnostics, but it's common for all services. It doesn't matter if they have repaired your car or simply plugged in their laptop and made a fast diagnostic. It also works that someone does and it must be paid and taxed. If you don't want to pay taxes or money for such work then just buy an automotive diagnostic device and do it by yourself at home, I can recommend you to buy this one https://thinkdiag.co.uk.
