bad tilt trim?

[teamster98]

I have a 1990 Alpha 1 that does not go down.The switch when pressed for down puts the drive up(probably reversed wired on cylinoid ?).I had to bleed to get unit down.Does nothing when trying to put down,no noise from pump.Could it be bad cylinoid or limit switch?

Head up to the adults only sticky at the top of this forum.
Download Mercruiser service manual #6
Troublshooting section give details on testing and wiring diagrams.

You could probably spend an hour or two in the Adults only sticky, there IS that much information there to look at.

Sounds like the wiring is all scrambled up at the pump/silenoids.
