NECO Autopilot Update

Cool, good to know.
My idea was more like being able to give a signal directly to the steering relais or give the steering unit a wrong compass signal. This way it would be possible with a bit of DIY to fit any digital remote control. I just have to know where my connection points would be. I've already studied the wiring diagram and figured that pin 12 and 13 must be the one but I didnt come up with an elegant solution yet :)
 
I think sending a wrong compass signal might be challenging. Also intercepting the selsyn output would need some maths. An elegant solution? Something that can remoting mechanically rotate the course setting knob to the new course you require?
 
Good morning All.
I have an Oyster 46 from 1981 which I am refitting in Viareggio. I have decided to remove the old Neco Auto pilot and therefore have a lot of spares which could be useful to someone refitting their system. Please PM me if this could be of interest to you.

The Neco Drive cannot be driven like a reversing motor. Inside it does not have permanent magnets but two coils (one "shunt" and one "series") that need to be fed with fixed polarity. The change of turning direction is accomplished by reversing the polarity of the "armature" only. You can drive the Neco motor with any modern autopilot that is able to drive "solenoid" valves but you have to keep the existing relays and fit a new third relay to control the clutch and the "shunt" coil. The changes can be made by anybody with a little DIY ability and will cost just the price of the third relay: less than £5.
Whoever needs further directions is invited to PM me and I will be glad to help.

ps: angelsson, I realized we are already in touch...

Hi guys,

Can somebody send me

Yes I have a copy of Daniele's tests for the Neco. PM me an email address and I'll forward it. I have notes of adapting the Drive Unit to 'mate' with an Onwa Auto Pilot. The procedure will probably explain how you can 'mate' a pypilot. All the Neco Drive Unit wants is some commands. A basic relay will be needed in the Neco (simples)

Hi, could you please send me Daniel's test for the NECO? Thanks :D

Hi can you pass me those notes please? My Neco has been integrated with a Garmin GHP 12 and I'm interested to know how it was modified in case I need to maintain.

If I get some free time I’ll put together more detailed information and photos of my setup so you can fill in the gaps with your expertise. My setup should work with any current autopilot designed to control a hydraulic motor. It should also work with any NECO motor regardless of power draw or voltage.

Hi Patrick, I've got a Fisher 37 with a Neco drive and compass, now linked to a NMEA 200 networked Garmin GHP 12, it has a Veco rudder reference. Would the drive have been modified to work with the Garmin?

Good day,
Would you maybe send me the test document for the neco as well? My email is sbast (at) xs4all (dot) nl .
I am trying to figure out why its not working properly.
I've taken it out and have it on the table now. I have a drawing from a pypilot rebuilt video and the document from Daniele about conecting another type of CU to the DU. I have a 17dr8 with 24V engine. The engine is turning, but the clutch does not properly engage when I put 24V on 3 and 4 of the 16 part block and then manually switch one of the relays. From what i understand this can be because the clutch needs to be engaged seperately, but I am unsure about the voltage to use, since the CU seems to work on 12V and the motor on 24V and in the drawing they both seem to be connectes to the clutch. Same when I follow Daniele's drawing where the clutch relay is connected to 7 and 9.
I would be very happy with just the test pdf, but if anyone has any other tips for me they would be very welcome. I am just starting to get to know more about electronic systems 🙏😊.

Thanks in advance,
Best regards Sanne (SV Ilios)
