Was having a problem trim would not go up . I have jumpered the sensor out and the trim works up , Is there a way to rebuild the sensor on the trin for alpha one , or replace without going through pulling the leg bellows ect . I opened it and scrached the visiable conections not sure if theer is a swich in side the unit ?.

Cleaning Trim Limit Switch & Trim Position Sender

For the trim/tilt problem you are experiencing, if the wires from the limit switch (port side) and trim position sender (starboard side) are in good condition, they (Switch or sender) can be disassembled to clean out the old hardened grease. SCRIBE the sides of each one and the OD for a reference mark before removal. Clean out the old grease and pump fresh Mercruiser 2-4-C grease thru the zerk fittings before reinstallation. Clean the small brass contact points with solvent and a pencil eraser until shiny; repack w/ 2-4-C grease and reinstall by aligning reference marks.
 
Hate to be the downer but the OEM wires for the trim sender units get brittle and break. You can either try and splice which will be temporary at best or replace the trim sender unit and wires which have to be fished through the gimbal transom assembly. You can find replacement kits just about anywhere for about $90.

OR you can jumper and hardwire the trim/tilt to just tilt full up or down with no limit switch. You just have to make sure you never raise the unit too far while under power. That's how I got mine set up. With Bennett tim tabs it's no problem lower the drive and leaving it there.
