EV Service required - Contactor weld(?) help needed

[Dilbert100]

Hi All, hope someone here can help out or maybe point me in the right direction.
My Outlander is displaying 'EV system service required' and has restricted performance etc which happened after my first (and last) ever attempt to rapid charge. Research and other forums etc have led me to believe that the issue is most likely to be a contactor weld issue that has triggered the fault code. A longshot perhaps but it has also been suggested a strategically aimed 'wallop' or two with a rubber mallet/piece of wood might encourage said contactor to let go and return to its resting position. I'm not holding my breath on this but it has to be worth a try, the only problem I have is knowing where the contactor is located and where to target the blow!

Does anyone have any ideas.....
