Hi jFrey04,
i guess the flashing and beeping should actually indicate, that you are starting the motor but you are still hocked up to a power plug. The control unit gets the signal from the AC battery charger which is located under the drivers seat (in my Columbus 540AD). It is a green or green and white wire if i recall it correct. I had to rewire it when i updated to my new Votronic Triple charger. When this wire gets 12V, the control unit assumes that the car is plugged in to AC.
So maybe your charger is broken or the wire got damaged or gets wrong signal from somewhere.
