I will test it out as soon as I have some spare time !!!

Looking closely at Nick's solution I was wondering what exact problem he had found on the power supplies. I'm having a related problem with the relay switching (grounding outputs) after 2 min. from start up (however on a CS8416). The only connection to the relay from the controller chip is an "input port controller". Must there be voltage on this?

To work correctly, DIR9001 must be connected to that resistor

What will happend if it is not connected?
I´m running mine without it connected.
