After a heavy rain storm, the outside ground fault outlet was tripped and the car had not charged. I disconnected everything, reset the gfci, and reconnected the cable. The green light came on and the red fault light flashed. I unplugged and left the cable in the sun. After several hours I reconnected the cable. Sometimes it tripped the gfci and sometimes the green and flashing red appeared.
Later that day I plugged in the cable. No green light and a solid red fault. I tried a different gfci circuit, and no lights at all came on. The cable is dead. The car is 3 years and 4 months old. I have purchased a new cable, and put a plastic bag over the box on it in order to protect from the rain.
