On a alpha One I have 2 trim sending units that connect to each side of the lower unit how do they work right side does one function and the left does another? If so what ?<br /> I notice when I move the right side the trim guage moves but when moving the other one nothing happens and how do i reset them since I took them off last year becasue the wire broke its never been right when I move it and look at the gauge an it moves ok a bit and then jumps to the far right....
