This has happened a couple of times recently : Plug the Tesla in to the home charger. It's low, around 15% of battery. It starts to charge, then disengages, then starts to charge, disengages. It repeats until I unplug it, roughly 10-15 seconds for each on and off. I can hear the relay in the charger clicking on and off and it's kind of alarming. Unplugging and checking the charger port and cable didn't fix it. I ended up rebooting the car with the steering wheel button trick and viola, charging resumed as normal. Can't tell if this is a problem with the car or the charger now. Anyone else encountered this?
