@LilahTovMoon He should use his meter to verify that he has ground continuity from the earth pin on the charging cable. The earth pin of the socket on the vehicle should be bonded to the chassis - easy to verify with the meter. This means the vehicle body should be connected to the local earth when charging - if it isn't then there is a wiring fault in the charger or less probably the bond wire has fallen off in the vehicle. My money is on a charger wiring fault. 5 comments
@X31Andy @LilahTovMoon @Stinson_108 @LilahTovMoon Tesla home chargers are AC - that is why you can AC charge Teslas on other vendor chargers - lookup the specification for J1772 (they send a 1KHz PWM signal to select charge speed). Fast chargers are DC but cost a fortune and are not used at home unless you have a seriously oversized supply and stupid amounts of cash. In any case the vehicle should be connected to the local earth via the connection - this is a basic safety requirement.  @X31Andy @LilahTovMoon I agree with this. It's pretty standard for automobile wiring to connect the negative side of battery systems to chassis. Something is energizing the chassis, and I'd bet it's something wrong with the charger. |

Pff. The charger should detect continuity on all lines before delivering 300-900 VDC.
