I am not familiar with your particular model autopilot, but I do know that Raymarine autopilots can be fussy. All must have a compatible gps feeding it, of course. All must have a rudder angle indicator if your auto pilot connects to the wheel or rudder instead of directly to the tiller.

Your description of the motor running but no output certainly does sound mechanical. Sometimes things get stripped. Usually there is some other sounds, sometimes not, based on the number of teeth, etc.

For example: extended or retracted always has the unit stop.... The reason is imagine a tooth missing at one position, ....if you somehow got past that position, presto function....until the unit went back across the problem position....
I expect that there are electronics that decide what your auto pilot should do, but it boils down to a motorized unit, and IF, as you describe, that units' motor is actuated, I would expect output of some kind. The picture shows what looks to be a tiller mount controller, also there are other designs that may connect to your wheel, or some connect down at the rudder post...All need to go one way or the other when the motor is energized.
Do keep after and make this unit work, I think it helps you be able to run the vessel with less help....

The Raymarine ST8002 Smartpilot the unit powers up but does not work when the auto mode is selected. The hydraulic motor does not engage when a course is set. What could be the source of the fault?

According to a post on the Raymarine forum, this error message could indicate an issue with either the steering, the drive unit, the rudder reference unit (if fitted), or the course computer . The post suggests a few tests that you can do yourself to figure out which item is causing the issue.

I suggest that you try the following steps:

Check the connections between the ST8002 SmartPilot and the other components of your autopilot system.
Check the calibration of the ST8002 SmartPilot and the other components of your autopilot system.
Check the hydraulic fluid level and the hydraulic pump pressure.
Check the hydraulic pump motor and the hydraulic pump solenoid valve.
If none of these steps work, I recommend that you contact Raymarine customer support for further assistance.

How do i recalibrate the st4000 tiller for the starboard side

Hi Tina!

The ST 4000 is factory default to the starboard side. If you require a port side mount, see chapter 7 of the manual to which I have provided a link below. (3.16 MB) About halfway down the page.

The text reads as follows:

OPERATING SENSE REVERSAL

Press +1 and -1 keys together for five seconds.
The display will then show port or starboard and the phase of the autopilot will automatically change.
The control head will automatically revert back to its normal operation within 5 seconds.
Note: This should normally only be required if the actuator is port hand mounted.

Hope this helps.

(Sorry about the orientation of the manual, it's pretty cheesy coming from Raymarine.)

jimtippettau:
Which drive are you using with the AP24, is it just a hydraulic pump on a powerboat, like our RPU80, or is it a hydraulic linear drive (like our HLD-2000) or draglink drive (like our DD-15) on a sailboat?

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

Raymarine ST6002 Smartpilot Alarm Message ''Seatalk Fail 2''

Very possible that the Wind instrument has a defective Seatalk interface - it happened to me. You could try your Wind in another boat, just connecting it temporarily to the Seatalk Bus - if it jams those it is the problem

Your autopilot should have a separate Course Computer such as the 100, 400, S1... somewhere. Some models have two SeaTalk busses, and the recommended installation is to use one bus for the 6002 control head alone, and the other bus for instruments etc, so a SeaTalk fail on the instrument bus will not disable he Autopilot. I retired my boat this way (after the dealer took the one-bus shortcut).

The real solution is to have the Wind instrument fixed. The cheapest work-around is to cut the yellow SeaTalk wire between the 6002 and the Wind, so that the Wind instrument gets power but does not affect the data bus. That should let the AP and Wind each work normally and independently (no Wind-angle mode on the AP).

Raymarine have a forum you should join for more info and help.

Sea talk failure

Remove all wiring from 4000 head, hook up only 12V, if seatalk fail continues, it is the head. if seatalk fail goes away, hook in instruments one by one until the bad head is found. Seatalk is 12V red, Ground Screen(bare wire) and Data yellow (pulsing voltage). good luck 847-746-0100 John Barry
