Re: Raymarine Autohelm/Pilot ST4000

Capt. Dan:
I just posted a problem with my ST4000+. You may be able to help.
The head always reads 50 Deg. I disconnected the wires from the Fluxgate at the head and reconnected. Not help. I will disconnect and measure the resistance per the manual. Any thoughts or suggestions?

Dan, thanks - had a look inside the motor/gear casing and can see what to do now. All I need now is a controller of some kind to drive the thing.....

Thanks for your help, much appreciated

To convert to a 2 wire, remove the small circuit board on the back of the motor. Solder two wires to the tabs on the motor and you are done.

Hi Brewgyver

Thanks! We have a 40 year old Fisher 30 - a very sturdy motorsailer. When she was built she would have been considered a large yacht and she is still capable of squashing some of the newer bigger but lighter boats as she weighs in at around 7.5 tons laden. Sailing here has been good this year but the gales are just starting to get a bit too frequent - another gale warning just broadcast.

I must post a profile picture showing the boat.

All the best

Speaking of posting more.... a friend of mine sails a Fisher 25. We all sail on the Columbia River in Portland, OR.
Fishers are quite rare around here.
I've been out for a sail and was impressed at how much boat interior there was and how solid it felt. Takes quite a bit of wind to move it, though, and pointing is not what it likes....

Anyhow, do contribute when you can. Everyone has something to add! (Well, almost everyone...!)


ps: I used an Autohelm 4000S on my current boat for a decade, and then upgraded to a Raymarine X5. The software is supposed to be better, but I do not see any obvious changes in the hardware quality...

Andrew, to help with your post count, what do you sail, and how is the sailing in your part of England?

Andrew.. from what I understand Dan is very helpful (and knowledgeable) with this sort of thing.. once you get a few more posts you might send him a PM if he doesn't notice the resurrection of this thread. I think his email is somewhere on this board too...

Re: Raymarine Autohelm/Pilot ST4000

Dan, hi. I saw your post (from last year) about the conversion of a four wire Autohelm motor to two. I have one of the old compass rose type AH3000 from which I want to use the motor on another pilot controller - not sure which yet. I've identified that the red and blue wires will drive the motor fwd or reverse, but don't quite get the yellow and green, other than measuring that they sit at around 4v when the pilot is not turning the motor and (depending on rotation) 8v or 4 v when it is. Wondered whether they were either feedback or damping in some way?

I'd really appreciate your advice about what the wires do and how to convert.

Many thanks

Andrew Thompson, Fisher 30 "Jojac"

You would also need to add a plug to the motor wire to attach to the control head. The 3000 and ST3000 heads can usually be found on ebay or maybe in a local used marine store. Email me if you need more info about the 4 wire conversion.
