I was excited as I am sure most of you were to finally having an electric car. I drove a friend around picked up my kid from the movies. I have a 15 mile drive to work so I pulled in the garage and plugged in the charger. It turned green then flashed red. We have a detached garage, but it has been updated in the last 6 years with new wiring and GFCI outlets. I tried it in the plus inside and on a couple external plugs and it changes color a couple times but then turns green. I tested the ground with a volt (no pun intended) tester and it tested just fine. Has anyone else had this error with the charger? If so how did you fix it?
