When I power up my EC2 the program select button glows red.  I am hoping that this is normal – although green would have been a more re-assuring color.  The interesting thing is that when I supply power to the main buss (but not the EC2) the LED also glows red.  Is this normal?  The juice is getting to the EC2 via the injectors (which are powered by the main buss).  If I unplug the injectors the LED goes out.  Seems strange, but I’m hoping everything is OK and hope I don’t have to start re-wiring.
