2017 Mercury 150 4 Stroke

Trim gauge not working. Shows down all of the time. Turn key off gauge jumps to up position. Turn key on gauge goes to down position. I have changed the position sensor and the digital to analog converter. I have by passed the brown wire with white stripe from the analog converter to the gauge and still no change. Every now and then it will start working and just as quickly stop again. I have checked all known connections. I’m at a loss!
