    Went to charge today.

    Plugged in UMC, got red ring and red LEDs on UMC flashing 3 times.

    Disconnected from car, disconnected from wall for 30 s. When I reconnected UMC to wall, it began flashing again.

    Will call SC, but since UMC is flashing without connecting to car, assume it has gone bad.

    Glad I don't need a charge right now...
