Just when I think I've got my boat ready for the summer more problems arise. I went to put it on the trailer Sunday and to my dismay the trim does not raise. I pulled off this lines, lifted the outdrive and tied it up to make it home. So far I've determined: Battery power is good, Up solenoid is good (I replaced it), power is making it to the trim switch on the throttle and back out, power is making it to the port side limit switch (I haven't checked the starboard, but it doesn't look like the upper wire is running to it). This is where I'm stumped. I pulled the limit switch off, but I was unable to figure out how it worked. Does anyone have a link to an article on how these are supposed to work along with adjustment/instalation procedures? If the current is supposed to run back up on the other wire I think I have a ground somewhere on the return wire (the one that runs back in to the boat). How do these wires run through the transom? Do I have to take my outdrive off to figure out where its grounded? Any advice is very much appreciated.
