Just had the transom rebuilt on the boat, the tilt/trim was working fine, but know the tilt/trim works fine on the motor up and down no problem. On the control it will trim up fine but not down. When you push the button in the relay doesnt click. I check the power and I have power on the wire coming from the control but cant trace the wire due to the harness wrap. Its a light brown wire. I feel like its something simple like a bad connection,fuse, or bad wire. I cant find any in line fuses. Any suggestions?
