I just purchased a used 2016 Ford Focus Electric yesterday but I am having an issue I'm not sure I should be concerned about. When I brought it home last night and tried charging the car with the supplied Ford 120V EVSE, the red 'Check Outlet' light on the EVSE started flashing about a half an hour in. I unplugged everything and moved it to another outlet on a different circuit in the garage. I didn't see the red light this time so I went to bed. This morning the red Check Outlet light was flashing again, but this time the red 'Fault' light was also on. I moved the EVSE to a dedicated 20 amp outlet in the laundry room this morning and a short time into the charge, the flashing red Check Outlet came back on. The car appears to still be charging while the Check Outlet light is on, but eventually it stopped when the Fault light came on. I looked at the activity in My Ford Mobile and it shows an External Fault from early this morning but nothing is showing for the fault light that just came on about 20 minutes ago. What could be causing this? Is it the EVSE or something wrong with the car itself? Is it still ok for me to charge while the Check Outlet light is flashing? Any advice is greatly appreciated.
