My trim has been working fine all along and then suddenly the other day it would not do anything when I got to the lake. Later on that day it was working fine again. Then again as I was coming back from the lake the trim only went up about half way. I have a 1968 Mark Twain with a Mercruiser 120. Is there a certain wire that I need to check or something. I have never dealt with trim before so I don't know.
