Is anybody using a level 2 GE Wattstation for i3 charging? I purchased a used unit and it is giving me a fault with the i3Rx and the X540e. Does not charge either car. I thought the unit might be defective, but a friend of mine was in my home yesterday and charged his Chevy Volt without issues. I read somewhere in the Wattstation manual that it might be incompatible with cars that have fan activation while charging. Has anyone gone through this issue or has any recommendations other than getting a new charger?
