I thought since my garage isn't air conditioned, and the temperature in there has been hovering in the 90s, maybe charging at 120v with the "Spare Mobile Connector" cable would be easier on the car. It turned out not to be easy on the cable! I came back and found charging had stopped -- pretty quickly, looking at the range readout. The display told me to connect the power cable, but it was still connected. Uh oh! Further investigation has shown this 120v connector to be dead as a door nail. It does nothing. There's no light. The reset button does nothing. The test button does nothing. There's no evidence of power even going into it. So. . . Any suggestions? Is this a known problem? Is it something easy to fix? Or are those electronics in the "snake head" part of the connector even needed, really?
