I recently installed two ACU 400's and two type 3 rams. Obviously only one can be powered at any given time. I daisy chained the two ACU's off of one rudder sensor. One of your moderators indicated that could create problems so I disconnected the second ACU. Both units work perfectly without the rudder sensor, however if I connect the ACU to the rudder sensor it sometimes goes into violent oscillation, perhaps once an hour, more often if the weather is rough. I can stop this by grabbing and briefly holding the wheel. I've run setup as indicated in the manual and ensured that the system is thoroughly bled. Any suggestions.
