Kevin,
Did you perform a tug test on the Robo Rio power cables? I have seen this when power wiring is just a little too short in the push type connectors. Others have reported damaged power connectors that appear to be OK but in fact are partially depressed allowing a pretty good connection but not a perfect connection. The only sure sign is to look down into the terminal with a bright light and watch for the contact to return to fully closed after pushing on the actuator.
