Hi Chuck - hoping you have some insight.

My new to my WJ from 1999 has a complete Raymarine AP system that I've been trying to get operational. It includes a Type 100 CPU, Type 1 pump, Gyro, Rotary Rudder Ref, ST6000+, M81161 Joystick. There's also a remote KVH compass that I _think_ is attached.

Step 1 - the LCD screen was burned in, so I replaced it. I was then able to see the rudder indicator didn't move as I moved the helm, so I replaced the M81105. I was then able to drive the rudder both directions with the ST6000+, but only to starboard with the joystick.

Step 2 - I had a marine electrician look at the joystick, he reported the wiring was broken (this comes up the Stidd chair and out to the joystick at the arm) and fixed it.

Step 3 - I took the boat out, engaged the AP, it turned a bit to starboard and hung there - didn't center back and the boat continued on a long arc to starboard. I engaged the joystick in Manual, it moves the rudder to starboard, does nothing to port (just like before). But now I cannot drive the rudder to port using the ST6000+.

Before I replace the AP with an EVO (which I installed on my previous trawler) I would really like to get it working. In particular, I plan to re-use the rudder reference and the pump (I REALLY don't want to get into the hydraulics!).

I get that they joystick might not be working, but the Type 100 turning to port and no longer doing that has me buffaloed. Can you think of a simple test I can do to isolate the issue? Or - even better - a connection that might have failed that I should check?

Any guidance greatly appreciated.
