Hello,
I Just picked up my new MS75 on Saturday, and I have been having issues with the UMC. This is the new Gen 2 UMC that has a max of 32 amps.

The UMC will be green, I plug it into the car and the charge port turns red, and the UMC T flashes Red once. If i unplug the UMC and the car, then plug it back in, then it will charge, sometimes i have to go through this process a few times.
I looked up the single flash and it states:
"1 flash Ground fault. Electrical current is leaking through a potentially unsafe path. Unplug the Mobile Connector from the vehicle and then plug it back in. Try a different outlet. If the error persists, contact Tesla."
Whats Odd is if i plug in our clipper creek j1772 into the same outlet and use the J1772 adapter it has no issues. The UMC is using a 14-50 with #6 wire on a 50 AMP breaker, Installed by a licensed electrician.
Once the UMC starts charging i get 28mi/hr at 241v and 32Amps.
Any chance i have a bad G2 UMC ? Any Advice would be helpful.
