Just got new 75D. apparently charging cable is 'smaller' gauge and won't charge as fast-no problem. However, when I plug it in to my outlet and then to the car, the circuit breakers trips on the cord. When I look at the panel in the car it says 48V. I manually reduce it to about 20, unplug/replug at the wall outlet and it works fine, then I can increase the 20V to 32V and fine. But every time I plug in, it resets to 48V and circuit breaker trips?? I had a P85D for 3 years using same exact wall outlet and never had a problem. Don't think its the outlet so not sure what to do next. Advice?
