My dad was doing some experimenting with the UMC to discover how it determines which adapter is plugged into it. The goal was to get 24 amps from a 120V source without buying the proper adapter from the Tesla store. It turns out that the two communication pins (shown in the picture below) have a resistance across them, and this resistance tells the UMC which voltage and current it should look for.
Drill till you get an open between ground and sense. Adjust the pot to 30k Ohms and it will take 120-240vac at 24amps.
What do you guys think?
