malfunctioning autohelm ST4000

[sailgirl20776]

My auto pilot is no longer functioning. The electronic unit is working and receiving data from sea talk except information is not going to auto pilot motor. It seems like there is no electricity going to the drive port. Checked if motor is working and it is. Any ideas of what else to check?

Been there....

I have replaced all of the components of my ST4000 over the last few years, flux gate compass, the head, and the wheel drive.I suspect your control head may be bad. Have you called RayMarine, they will help you diagnose the problem.
