It has proven useful to me to understand the workings of the EC2 and may be useful in diagnosing what is happening with your system. It requires either a laptop with a serial interface or a USB to serial adapter, or an IPAQ with a serial interface. A voltage level converter which converts the 5 V EC2 signals to RS232 levels and costs about $20 is also required. If the EC2 is accessible and a 1-inch long connector can be inserted between the EC2 and the existing connector, no wiring changes are required. If you are interested in trying this system, let me know, and I'll send you a CD with the software and instructions.
