Motor trims down fine, but won't trim up. Can hear the 'up' relay click in when the motor or helm switches are operated, but the trim/tilt motor doesn't run (with either the helm or the motor mounted switches). Tried swapping the 'up' relay with another, but no difference. I suspect a wiring problem, but haven't checked it out yet.<br /><br />Motor had been fine a few weeks ago, prior to changing the lower voltage regulator to the new style.<br /><br />Any suggestions?
