Greetings, I am inquiring whether anyone in the SF Bay area has an original Tesla HPWC that I can charge my 2010 Roadster Sport on as a test. I have an evolving problem charging my car that has been difficult to understand. Charging just stops at approx 55% of battery capacity. The local Tesla Service center has done diagnostics and an annual service and says that my car is fine and there must be a problem with my home circuits or my charger. They recommend that I try charging the car on someone elses equipment. I find this hard to understand since I have the same problem at 3 different homes on their 115 V outlets with the original yellow cord, at 2 different homes with 2018 and 2020 S/X/3 240 V wall chargers and my Sharp CAN Sr, and at a home with the 240 V Mobile connector 14-50 Adapter and my CAN Sr. Still, I want to comply with the service center’s suggestion and eliminate the CAN Sr as the cause. Thanks, W
