2016 Tomcat F21 Surf system help

[cafish]

Hey there - been scouring forums trying to find some help. I'm trying to diagnose surf system trim tab operation and have some solid ideas. What I can't find is just a video showing normal and expected operation of the surf system digital display. We have the surf switch system under the throttle (switches for R/L and center tab and a red button for "switch"

 

Re the computer, is there a video showing normal operation? Interested in switching from manual to auto operation of the surf tabs and adjustment. At this point, I can't even confirm if I am indeed in manual mode so unsure if the tabs are responding normally.

 

Problem description:

Turn boat on, wait for system to boot up. Fill ballast tanks hard and soft both sides. Put boat in Surf Right, wave shapes up great. Try to enter manual mode to play with how much tab is deployed and no response. Switching to Surf left, the right side wave is garbage and so is the left side. Center tab works fine.

On the fly, if I press the little button below manual while in surf R and then press surf left, the tab deploys but never more than 75-85% on the guage. The surf R tab deploys to 100%.

Neither tab seems to respond to tab switch input when I press the button underneath "manual" on the computer screen.

 

Plan right now is to check wiring, fuses, and test actuators using a 12V battery but in the mean time, a video showing normal operation and what we should be seeing would be very helpful.

Thanks for the help!

On my 2016 F22, manual operation requires using the switches down by my right knee.  FWIW anything less than full deployment makes the wave worse, not better.
