Just to confirm, are you setting the dip switches as shown below?I have a 2014 Model S and a Gen 1 HWPC. I just installed it on a 60A breaker. When I set the dip switches to 60A, the car only charges at 12A. However if I set the dip switches to 50A, the car will charge at the correct rated 40A. Any ideas what is going on here? The HWPC is giving no error lights or anything.
