Well, Friday the 13th rears its ugly head. Among about 5-6 other breakages around the place, my original 3 1/2 year old HPWC has decided to stop working. The HPWC still provides a pilot signal to the car, the green light is still lit on the HPWC. When the car sends the signal to start charging, there is no contactor close. I isolated a car failure by trying it on a different car, and trying my other HPWC on the same car. I isolated a cable fault by putting the HPWC in test mode and holding down the reset button -- no luck and no voltage goes to the contactors. It appears the board had a fatal failure. The main board of the wall connector has a red LED that's slow-blinking. I can hear a high-frequency noise coming from it. It's dead, Jim. Anyone else experience a similar failure?
