@LilahTovMoon That multimeter measurement is terrifying, especially if you can pull a decent amount of current through the chassis like that. (Though I would have expected reports of people being shocked/electrocuted making the news already.)

The first part looks a bit sus, like they might have the red wire stuck in the charging socket while it's charging.

When the bulb arcs, you can see the charge port status indicator goes from charge complete to fault, and the tail of the red wire appears to have been pulled out from between the charger plug and socket as the person on the left backs away.
