Hello everyone, I’m new to the TMC forums. I just got my 2018 MX last week. I had a 240v outlet put in my garage. After reading posts I set the charge to about 80%. When I plug the car in overnight, the next morning the light at the connection is solid red. Was flashing green when I plugged it in. I read that the light should be solid green when fully charged and red means a problem with wiring. Am I doing something wrong? Thank you.
