My Gen1 80A HPWC started acting up a few weeks ago and I cannot figure out what is going on. A few weeks ago I started getting a "Charging Stopped" message and the car would not start charging. I can hear the switch click in the HPWC like it wants to connect. Sometimes I could pull the charger in and out of the car a couple of times and it would finally connect and charge. This has gone on for a few weeks before getting progressively more tempermental and just showing the "Charging Stopped" message all the time. When I open the HPWC, I am getting a single flashing red. I know this is supposed to indicate a ground fault so I called an electrician and he came over and sunk a new ground rod and tightened everything. The ground is fine. Even after turning off the breaker and letting it sit or resetting the HPWC, the flashing red persists. The red light comes on right away when the HPWC is energized--even without being connected to the car. My mobile charger works fine but I have dual chargers and want 80A charging so I'm trying to figure out if there is a component on the motherboard that is bad, if it's the cable or something else.
Can anyone help or provide advice on what do try next?
