I tried this on another forum, with no takers.
My boat came "equipped" with the Unipass linear actuator below, neatly wired into the black box shown, with a cable from the box leading...nowhere.
The "head" unit for the autopilot had been removed a long time ago.
Does anyone have access to any manuals on this unit? Or just:
1) How to test the actuator to see if it still works?
2) Is it even possible to connect a new "head" to this old unit?
