This is a good device. Ray marine has an extensive library on-line. I have usually been able to find what I need there. May take some digging though.

Hi, If you are looking for Autohelm service manuals you may find them at http://sdmarine.online.fr/Service%20Manuals/Autopilot%20Systems/

Try this pdf manual. Its for the latest model but I also have an ST4000 and the instalation looks pretty much the same. http://www.raymarine.com/ProductDetail.aspx?SITE=1&SECTION=2&PAGE=88&PRODUCT=4176

There is a screw that hold the lever.If that screw gets loose the lever gets loose and drops down when get jerked or passes through bump. A short loop of chord around handle and drive housing which seems to do the trick.----------- Open the round cover and have a look.If the belt looks worn out it also needs to be replaced.check the tension of the belt as it is an "over center" clamp so should stay engaged even without the aforementioned bump.If the belt tension is loose then it has to be made proper tight ,if its got worn out then it needs to be replaced. ------------- There are many other ST 4000 Ray-marine users facing the same problem:--- some users mentioned that they attach a small length of elasticated cord to the binnacle (like thin bungy cord) and this blocks the lever from dropping by itself or getting disengaged. ------------- In some other cases,this was the reason of problem:--- Read as follows:--- The lever moves a cam that tensions the belt. The pin that locates the lever position relative to the cam gets corroded. This cause the cam-position-to-lever-position relationship to change slightly which means that the lever didn't quite positively lock (due to the belt tension on the cam). If this is the case in yours then it can be fixed temporarily with a handy bit /nail or drill bit of something to take the place of the pin until you could get a new lever and cam assembly.--------------- This troubleshooting will help.Thanks.Helpmech.

Check power supply to the unit with a 50W 12V bulb as load,voltage should be at least 12V,with batteries full charged

what type of pilot?
Is there a rudder reference unit installed? if yes check rudder ref unit.
Does it does this only in auto?

Set standby and check if +10 and -10 pilot is turning in correct direction.If not See manual for installation drws and setup instructions.

The clutch lever for the black wheel unit st4000 has Autohelm reference N011,see at Westmarine,is sparepart is available

Search in e-bay ,there is a supplier

Hello,

You can get it at either amazon.com or ebay.com.

Take care.

No data would have to indicate a problem with the GPS input, I would think, although I've never had one of these. Check the cord, it could be defective. Couldn't find much technical info on these units on the net, but some parts aren't available anymore, so that's bad news. Anyway, hope this helps.

CHECK FLUXGATE COMPASS ,see google for check autohelm fluxgate.

Remove the connection to the drive unit and check if freezing persist.If not check drive motor and cable.
If freezing persist and compass is ok the control unit is faulty.
Verify if the compass reading is ok in four directions on standby.if not check compass or compass wiring.

Try to make new brackets for adapting to the screw holes on the rim ATTENTION the screws should NOT
go deeper in the rims as the original ones as they will interfeer with the internal parts and damage will result.

The wheeldrive is only a mechanical actuator ,it will not pilot ,it will only drive the wheel ,you need a control unit ,several 4000 or 3000 units are suitable ,
some have an internal compass others need an external compass

If the remote is the wire type ,check continuity of the wires in the cable ,specially at the bending places where the cable comes out of the connector and the control unit.,Cut away internally broken part of the cable,and solder again respecting the coulours ,or change the whole cable respecting the connections.

You can check it in 2 places:

1) the back of the control head
2) the motor itself. The wire plugs into the motor or the shaft coming off the wheel portion.

You should have approx. 12 VDC coming from the control head to the motor.

Normally the belt should be slipping around the drum if the pilot is disengaged,sometimes the belt does not slip smooth due to the conditio of the belt or dirt,grease or oil on the drum inside ,take the unit apart ,check for belt condition,exessive belt tension ,if necessary belt tension can be adjusted on the rear of the backplate.

The clutch lever shearpin is on the outside through the body of the clutch lever
