Weird behavior of a new UMC that the Tesla service center gave me about a month ago in exchange for a perfectly working one.
As you can see in the video, 35 seconds after starting to charge, the current reaches the nominal value (32 A), but then, 1 min into the video, the current starts to fluctuate, and drops to 10 A, together with the maximum current (at about 1:20), then increases back to 32 A (just before 2 min) and then drops back to 10 A again, etc. Later it drops to 13 A or 14 A. It's not the power source since it did that at two different locations (both with the NEMA 14-50 connector), and it's not the car charger because it charges steadily at 40 A on the HPWC at home.
So I suspect something wrong with this new UMC. I'll try to see if, by any chance, the service center still has my old one.
Anyone else has seen that?
