I purchased the high wall power charger with the Model S and have had since last March. After my house was re-built after Sandy, which was completed last June, I had the electrician upgrade the power service and install a separate 100 amp service directly to the charger. The charger has never worked. The green light lights, the car recognizes the connection, but that's about it. Back then I had read that the chargers were not able to put out 100 amp service without tripping circuit breakers and that it was being worked on. I also read that Tesla would replace the chargers once the problem was solved. So I figured I'd be patient and had the electrician install a 14-50 50 amp fixture, which I have been using as the primary charging source. So now that some time has gone by, has anyone heard if the home high wall power charger problems have been solved? Any news? Thanks.
