I run an older cable steer Minn Kota, so take the Ulterra part of this with a grain of salt. But that paused message is worth reading into.
If both stow and deploy pause, the board has usually lost its position reference, not the motor. It counts travel, and when it ran past the stow rest it stopped knowing where the bottom is. Then it thinks it is mid cycle and refuses to move either way.
First thing I would do is listen. Hand on the trim housing, hit trim down. If you hear the motor run a second and quit, the board is refusing the move. If it is dead silent, you have a relay or board problem and no button pushing is going to get those 2 inches back.
The ram on these is basically a screw jack. With the cover off, and the motor unplugged, you can often back it off by hand. I have not done it on an Ulterra myself, so read the stow section in your owner book before you put a wrench on anything. The gear housing in that tower does not forgive a slip.
Cheap thing to try first. Unplug the motor from the boat harness, wait a minute, plug it back in. That cleared a half stowed state on a friend's Terrova once.
Does the trim button itself do anything, or is it only stow and deploy that are dead?
thanks
