I have a nema 14-50 charger at home with 50 amp circuit. At times my model S will charge great, but almost every other night it charges intermittently - on for about 20 minutes then off for 40 minutes, then on for 20, off 40, etc etc. I have this documented because we have the PG&E home monitor which shows either continual charging or a saw tooth pattern of on / off / on. I replaced the charger cable and that didn't fix it. Anyone else have this? Any ideas? THANKS!
