[CA11] ST80 compass testing
I have the st6000+ auto pilot and no problem for the 2 yrs we have used it. We left a port and noticed the heading flashes once per second and varies plus or minus about 15 degrees. When Auto mode or Auto and Track are engaged the rudder is turning erratically for a few seconds and then goes hard to port. This is consistent when we have tried multiple times.

I have tested and confirmed the rudder reference M81105 is working.

The system components include:

E80 classic

ST6000+Autopilot cont,(which has the fluctuations on heading)

Type100 autopilot,(the ST80 is not wired directly in the ports marked fluxgate)

ST60 Tridata,(working)

ST60 compass, (which seems to work)

ST80 fluxgate compass, (it’s a steel boat and the compass is mounted above deck on a 6’ mast)

DSM300

Seatalk hs network

Is there a way to test the ST80 compass?

If it’s bad, what unit could replace it?

We are on a trip and hope to get the autopilot function back.
Any help would be appreciated
