[C320-list] Re-sending: Autopilot Issues - Possible rudder position sensor?

[Brad Kuether]

Didn't get any responses and thats not typical.  Anyone spar with their 
autopilot on the ST60 instruments set, specifically around the rudder sensor 
malfunctioning?

I was going to start by cleaning the connection.  Not sure what to do beyond 
that...

Well, first day out after Irene filled up the Chesapeake with debris, logs, 
barrels, and farm animals, we were told that most of it had cleared and 
decided to do a quick late afternoon jaunt.

When I engaged the autopilot (Raymarine ST60s), I was watching the display 
and it LOOKS like the rudder deflection sensor was malfunctioning, causing 
the the autopilot to steer left and right with no rhyme or reason.  It was 
tracking the magnetic course just fine.  It essentially rendered the unit 
un-usable.

Has anyone ever experienced this and if so, what did they do?  I have never 
really spent much time down in the locker so I am not even sure what the 
sensor looks like.

Any help would be greatly appreciated.  Thanks so much in advance!!!!!
