Autopilot Installation

Hi All

I installed a RM wheel pilot last summer and am having trouble gettting it to work consistantly. I have tried the fluxgate in numerous locations but the AP will only hold course for a short period of time before, along with heading drift, changing course. I am wondering where other 36T owners have their electronic compass installed or any other ideas??

Thanks

Re: Autopilot Installation

If this is happening while under sail I would suspect a manufacturing defect or a really poor installation.
If this is happening while motoring they're are a number of things that could be incorrect.
The fluxgate can be effected by vibration from the engine, rf from the engine, electronics nearby, not mounted virtically, moisture, heat, power cables nearby, electric motors nearby, etc.
Where does your data wiring for the unit run. Is it near other power cables?
It's a sensative instrument that needs to be mounted accordingly.
Also, if you find that the unit is "hunting" for a course correction the rudder control variance may need adjusting to suit your steering ratio.
Good luck.
