I just tried to plug my car in at home after a long road-trip and discovered that my spare connector won't light up green anymore. It occasionally blinks once or twice if I wiggle it in the socket but it won't charge the car at all. Bummer! The plug is labeled with model number from North Shore Safety that doesn't fully match anything on their website, so I wrote to them (as well as Tesla) to see if repair parts are available. I wonder if the current limit for the GFI was custom-adjusted for Tesla? I know that the GFI current sensitivity allows higher ground-current leakage for cars than indoor equipment. Does anybody know if the plug circuitry is custom-designed for Tesla?
