I plugged in the ModelS today and the power ring turned red. Looked at the Universal wall connector and it was red. I tried unplugging it and replugging it in and no better. I then took the NEMA 14-50 adapter off from the cable and this is what I found.
I've got a 50-amp dedicated line from a single breaker into my garage so I'm only wondering if this could have been some sort of power surge. I called service today and was able to talk to a tech after hours (more awesome Tesla service) and he said he hadn't heard of this happening before.
Meanwhile, I'm stuck in Sammamish without charging for the weekend. Luckily I have a 85kw battery so I should be good until I take it into the service center on Monday. They said they have extra cables I can swap this one out for. My main concern is a fire hazard if this happens again. Anyone have any ideas on how to troubleshoot on my end?
