I have a 2003 Tahoe by Tracker 3.0 mercury inboard fish and ski boat. Recently I replaced the trim switch cause it was old. Now that I have replaced it and checked/cleaned all wires, replaced solenoids beside the trim motor it shows that power is getting to the motor but still won't move up and down. What else should I try to do? The trim motor makes no noise at all when I pres the switch but the test light confirms power to the motor.
