[DG11] ST2000 sudden hard course changes
Hello!

we are using an ST2000 tiller pilot on our boat. It is an older unit and still has the name 'Autohelm' printed on it. During the summer, it happened a few times that the autopilot would very suddenly give hard rudder (to starboard). The pushrod was pushed out to the maximum extent, while the motor was still working against the stop. The conditions were very calm with perhaps 12 knots of wind and reaching. I immediately disconnected the power supply and re-started the device. Afterwards, it worked just fine but this behaviour can obviously be quite dangerous in some circumstances. Has anyone experienced a similar issue and knows if it can be fixed (and how)?

Kind Regards
Robert
