Re: trim limit switch
Which tilt n trim unit is this? Some don't have one and rely on hydraulic pressure limits to stop the travel out under load.
At any rate, the auxiliary switches in the boat are probably spliced into the control harness. Some I've seen use idc connectors (scotchlock, for instance) that expose the conductors to atmosphere, and in time they will rot and break off.
The trouble is either in the up switch itself or in the wiring from that to the common point, probably at the above mentioned splice. It wouldn't be a fuse if the down switch in the handle works. A limit switch would be common to all.
hope it helps
