I have a 2015 75hp Mercury serial number2B197510 model 1F754131D and the trim gauge quit working. I checked the fuses and bought a new gauge but the needle just stays up by the H and will not move with the motor. I have the brown wire with white stripe on the S terminal the black on the GND ternimal and purple on the I terminal is the wiring right. I am not sure what to try next any ideas would be appericated if you have one.
