Good news everyone! The Supercharger is operational! ... I think.
I stopped by a little after 8AM this morning. Tesla's contracted electrician was there tearing down the barricade. He asked me if I wanted to charge, since the station was operational! He told me Tesla was on site last night charging cars at each station and testing everything out.
Unfortunately, my car refused to charge. It could see voltage, and popped up the message that charging would start momentarily. Then it stopped and popped up an error to try reseating the plug. I tried this a few times, and also tried a different charger. No juice. I called Tesla support, but the site isn't even in their support systems yet so the rep couldn't log into it to do any diagnostics.
I suspect there is something wrong with my car more than the site. I had charging problems when I first received the car back in July and had to have the AC charging hardware replaced. This is the first time I've tried supercharging. I figure I'll try again in a few days when the site is official, or at the opening event. If I still have problems I'll follow up with the SC. If anyone else successfully charges, please post!
EDIT: Oh, one thing... apparently they painted the lines wrong. If you back into a stall aim for the white line.
The guy that was there this AM was working on getting someone out there to fix it.
