Has anyone else seen this (or know how to resolve it)? I had a HPWC installed the other day and during the install we followed the directions to perform a self test and everything looked good. Today, a few local Model S owners graciously came by the house to try it out. When we plugged in the cord to the 2 cars, the charging ring on the car went red (immediately), the charger showed a red light and the dashboard flashed an error stating that there was a "Charge Cable Fault". When we removed the charging cable, the HPWC light went from red to green. We tried a reset of the unit (a few times, in fact). During the install, I was very careful to make sure the dip switches were set to allow 80A charging (maximum throughput). The electrician followed all of the advice: used 3 gauge wire, a 100A breaker and he assured me the breaker box had the capacity to handle the load (the circuit never tripped during our tests). Our house has 2 x 200 Amp boxes. It seems to me that everything is set up correctly. We connected 2 different S85s with the same result. I've initiated a call with Tesla and I am waiting for a call back. I'm scheduled to pick my car up next weekend and I want to make sure that the charger is working before I get it. If anyone has any thoughts, I'm all ears! Thanks!
