    A few weeks back I noticed the the tabs were not evenly positioned when I started up the boat and the port side would not adjust fully to the up position (still had about a quarter of the way left). I saw the online video on how to calibrate, which I tried. Now, all I get is the alternating (left/right) flashing. I have tried the calibration process a few times, and the tabs seem to be moving fine while in that mode. Not sure where to go from here.

    Thanks, Vince

    I know this message is a year old but it does not say if you fixed the problem. I had the same issue when I upgraded to the ATP. I spoke with Bennett tech and was able to pin point the problem to a broken wire. The leads should have 240 - 260 Ohms and the controller looks for that. I cut the wire at the bad spot and then reconnected with low temp solder/heat shrink connectors. Everything was good after that.
