Has anyone charged a US Model Y before changing the module to a European one?

Hmm, it does not work with the Tesla or Fiat AC charger. I fit and lock the adapter, but they do not recognise each other and I get Cp_a004 charging equipment not recognized. I have not tried a universal AC charger.

Thank you all! The problem was the grounding of the socket! Thanks to Ludmil as well for responding and helping solve it.
