my drive will go into full up with the trailer trim switch on the dash. it will also go full down with dash and throttle switches .but I get no upward movement from the dash or throttle. im getting 12 volts out of both switches for up.
also my trim indicator is not working
any ideas

Bad trim sending unit on the drive.

thank you

could nt get mercury site to open so I just ordered standard trim sending units. was locating wires and found that I had 3 on one side .I believe I have a smart craft unit..Does that sound correct? would the same hold true as far as repair goes

the wires break where they go thru the transom.
