any help on this would be appreciated. I have bennet trim tabs on my boat, have had them for about 5 years. About 3 years ago we put the automatic adjuster onto the system as well as the manual adjustment joystick. My question is this, I know that the automatic always cuts out when you make an adjustment on the manual stick, however recently the manual comes on, but when you try to level the boat (set zero) it cuts out. I can't find any blown fuses in the line. any help? thanks.
