Question about Raymarine ST6001 S1G Hydraulic GPS Receiver

1 Answer

The S1G display occasionally shows no data. The autopilot works fine for hours then fluxgate seems to hang up.

My problem is as follows: My S1G unit is on my trolling boat now for 20 months always working fine in all wind conditions. Since 2 weeks the unit seems to have a problem. It suddely shows no data on the 6001 display and the fluxgate compass looks as if it is hanging. It stays put at a certain position. After a while the display shows that the fluxgate is working again and I can then use the autopilot again. You can then drive for hours in zig zag lines whilst fishing for salmon and seatrout, then it suddenly hangs up again. This problem is absolute new for me and very annoying. The unit always worked fine. What problem do I have?? When I drive a circle using the autopilot it nearly makes a full circle, but just before I close the circle the unit shows no data. Its crazy.... I have checked if ferous material is the reason for the disturbance, but I found nothing that was not there before as it worked fine. A reserve fluxgate compass shows the same problem!!! I have also checked if all cables to the S1G unit are fine and properly installed. Hope someone has an idea whats wrong. Thanks, Cay

Try to borrow a computer unit to detect if the fault is in the computer unit or the display unit

Raymarine told me the unit was faulty. I stripped and found corrosion on one side of the circuit board. After cleaning it worked again. I suspect there is probably corrosion on the other side of the board as well but not sure how to acces it. Afraid to break the CB trying to remove from housing

Check if rudder reference unit is installed as before ,it seems that the pilot sense that the rudder is turning the wrong way. check when giving +10 command the
rudder turns to increase the heading,if yes, it could be the wiring of the rudder reference unit or it was installed the wrong way after service on the rudder.
Is rudder position indicating correctly?

It sounds like the rudder feedback has a dead spot in the center of it. The replacement part numbers:

Autopilot shows "no rudref"

The rudder sensor works like a light dimmer, so you get 5V and ground on the outside two connections and a varying voltage between about 1 and 4 volts depending on rudder position

The linear drive should have an adjustment screw on the arm so that it can be adjusted to show when the rudders are central. you will need to centre upm the rudders then loosen the screw and adjust until the guage shows the centre position. May take some fiddling to get right cause sometimes when you centre it the guage won't read correctly in the port or starbord directions (won't go all the way over). May need to re-position the whole unit.
