I just got my used 2018 Model S, and had the Wall Connector installed last week. It worked when it was installed, but the next day, after driving the car and plugging it back in, it stopped working. Every time I plug it in, the voltage goes up to the 240's, but the amp stays at 0-1, then a clicking sound from the Wall Connector occurs, then the voltage goes back down to 0, and then this cycle repeats until I unplug the Wall connector.
The whole time, the Wall Connector is green signifying it is working well. I took the car to a friend's house who only has a NEMA 14-50 but it charged well. It also charged well on my home 120V outlet and on the supercharger. I checked the dip switches, with 1 down, 2 up, and the circular one on 9.
I called Tesla and they are sending me a new Wall Connector. However, I just wanted to get the opinion of people on this forum whether that will fix the issue...I hope it's not something to do with the electrical supply here in Ohio, which is not great.
