So I charged overnight the other evening, but when I went to leave in the morning I noticed the car hadn't fully charged. Drat. Checked the OVMS messages and noted that it was getting #954 DMC FW: Line Voltage lost Sync and #981 DMC FW: Bad State Transition alerts periodically throughout the night (as it tried to restart the charge, I guess). Tried to restart the charge manually, it started but stopped after about 5 minutes with the same alerts. Fast forward a few days... Came home from a business trip tonight and the car had fully charged using the 110v cable. Tried to plug in the UMC and the UMC is now just flashing green (8 slow flashes then continuous fast flashes). Test does nothing, reset flashes both red and green. My nearest service center is 150 miles away. Their Roadster tech is over in China and won't be back until mid to late November (I am also due for my annual). Anyone have any thoughts about the UMC? I will probably give it a shot in another location, but i checked the connections for the NEMA 14-50 and everything was tight so I don't think it's the wiring. If it is fried, what would you do? Model S wall connector plus Can II? Model S mobile connector plus Can II? One of the Model S connectors with the Roadster head on it (if this is even possible)?
