S-1000 terminology

[Captrichie]

Hello!
My S 1000 wireless auto pilot's computer has been checked as recommended, "Should the drive unit move the rudder in both directions, then the fault has been isolated to the autopilot's course computer, necessitating that it be serviced or replaced." The drive has polarity, and moves both directions, per the polarity change tests but only moves starboard when connected to course computer. (It moves starboard when I press controller in either direction).

Are the S-1000 computers still being serviced? (The hand held controller the hydraulic pump are in good condition.) Where should the computer be sent for service?

Re: upgrade: I don't need anything but a simple system, (the clover leafs, fig. 8, and circle patterns are nice), however I do not need point to point chart navigation, etc. What would be the most practical way to proceed if the computer cannot be reasonably serviced/repaired? For me, a compass guided autopilot would even work.

(My boat is a Sea Hunt Victory, 22.5, with a single 150 Yamaha 4s and upgraded with offshore Sea-star helm and hydraulics.

Thank you. The s 1000 system is /was so simple and effective it helped me land many fish when nobody could take of work. I fish 3-4 days, April-November- weather permitting.
Respectully, Chaptrichie
