Re: Wheel pilots - which one?
watching this post because I have the same issue with my ST4000.
It works fine for 1 hour or 2 then stops and the off course alarm goes off. Push stand by, then auto again it works for 10 seconds then stops. Hard to diagnose what the issue is, getting hot? The motor (drive unit) is fine.
You can still get a replacement flux gate compass but that doesn’t sound like a compass issue. I thought I read somewhere that the newer drive units work with that control unit, but if you’re sure your drive unit is ok that won’t help you. If anything goes wrong with the control unit, you either can try to find a used one online and and take a chance or spring for a new wheel pilot. I believe my issue is in the control unit, and I have no interest in a used one. Let me know what you end up doing.
