Autohelm ST 4000

[Tom H31]

We noticed recently that our Autohelm, when engaged, turns the boat in a big circle, instead of holding a reasonably constant course. Noticed also that the flux gate compass readout doesn't change with changing heading. Any suggestions as to what is happening would be appreciated. *o

How about wiring

Sounds like the flux gate unit is not sending data to the control head. When in standby mode, the compass heading should change. Could be wiring. Wire routes, and connection in back of unit. What happens if you "turn the boat" to set the autopilot as per manual set-up instructions?

have you added anything near the fluxgate

compass that could interfere? Ferrous metal, stereo speakers, wiring, atomic particle accelerator?

Thanks

Thanks for the advice. I will check out the wiring and hopefully it's a simple fix. And the atomic particle accelerator is mounted in the v-berth, so that shouldn't be an issue!
