First let me say welcome to the site. Those trim wires can get messed up pretty easy so I would double check those in the motor compartment and then I would use a meter to check to see if my switch is pushing current. Sorry for the lack of info but this is becoming a more frequented site and I hope the info will follow.
Now there may be more info about trim on the Minnesota site that might help, it has been around for a while.
Just acquired 11th boat, red 1988 cvx23. Well played with, runs well, hope to use it this summer and then do some restoration this winter.
3rd Glastron, (second Carlson was a GT150 ) this ones a keeper. I'll post images soon.
One issue that I haven't found any posts related to is the trim switch will not lift the outdrive every time it's used. Both limit switch and trim sender were
replaced 2 seasons ago. I've ran the boat 4 times now and it's only worked a few times, I've had to use the trailer switch to trim up.
I've followed all the directions to adjust the sender and the indicator works just fine, no matter how I adjust the limit switch no joy.
