Hi bought roadster 2.5 used came with three chargers. I use the high capacity charger without problem. Just installed a 50 amp 240 outlet to use the mobile charger. The outlet tests at 250 volts. When plugged into the outlet no red light when test button pressed. When plugged into the car I get the usual blue light followed by a brief red the car is not charging. I have tried 40 amp rate and 32 amp without change. Any ideas on how to trouble shoot? I don't have another outlet with that type of plug had bought nema 6-50 connector and installed that outlet. They have been out of the 14-50 plugs for a while. It's hard to find another 6-50 outlet to try it on.
