Been trying to get the trim gauge to work properly. When adjust the drive all the way down then set the sensor to show it's down. When i move the drive up it never shows any movement on the gauge.But when i start to use the trailer button to put the drive all the way up the gauge jumps past full up. My trim gauge has three lines in it full down middle and full up.By the fuel filter is where the wires disconnect for the trim sensor. Some one before me made a wire repair. If the wires were reversed would this cause it to act strange?
