[h=2]2018 Merc 90 EFI 4 stroke - Power Trim Up Does Not Work - Troubleshooting[/h]
2018 Merc Serial 2B4937##
Power Trim "Up" Stopped working - Need some additional troubleshooting help or direction.
1. Down Works on Both Motor and Throttle switch.
2. I Reverse Blue and Green wires to lift motor and Down switch elevates motor, motor runs fine in either direction, power is good, hydraulics good. Not Motor.
3. Reversed existing relays, still same symptoms.
4.Replaced Both Relays, still same symptoms when Blue and green leads are reversed and normal. Swapped relay positions and still same symptoms. Assume relays are good at this point.

5. Next Steps?
Does any one know where I can get an accurate wiring diagram?
Is there a fuse somewhere I am missing?
What would inhibit the Up only function? Is there interaction with a limit switch somewhere?
Does Calibrate do anything beyond a trim gauge calibration?
Any additional help greatly appreciated!
