Hi there Bruce...

Did it ever work correctly for me; No! I'm the second owner of the boat
Hunter 40 85 model.

I did open up the controller box - tested the transistors; all OK;
checked
out the pn# of the IC's several nor and gates where I will have to
completely dismantle the board to test - and build a logic table test bed
as
well...
Is it possible the previous owners electronics installer guy made a
reverse
wiring booboo - Does not look like it though?? Why; When the unit is
turned
on it is not supposed to spin all the way around to hard over and stop?

I kinda wondered how it knew the boat is going forward - Did the hold a
course for 20 seconds; then engage; where on one occasion over a minute
decide to slowly veer towards a buoy... others - hard over

Boats far away to far to check right now

I'm close to pushing the button on the purchase of a Navman autopilot off
of
ebay new
Since the drive motor is apparently compatible with the autopilot where I
do
not currently need to also buy a hydraulic pump and ram;

Apparently the drive motor is permanent magnet with replaceable bearings

Ought to be OK with a new setup; Includes rudder position sensor arm

Thanks Glenn Strazds


Like I stated, if it never worked correctly from the "Get Go", then
the most common problem would be a reversed drive power. Seen it
to many time to ignore. Try reversing it and see what happens, you
can't be any worse off by doing this test.

I have an Autohelm 500 on my CSY 33 . It works fine.

Couple of questions. You do have a manual and understand how to use
this, yes?

Second, is it possible that there is interference with its internal
compass?

(I could not figure out why the PO mounted the controller so far away
from the nav station. When I read the manual I understood why).

I haven't seen anything to confirm you have checked your rudder
reference transducer. If you haven't you should disconnect first and
then check for red to green of 5K ohms and green to blue of 0 to 5K
ohms for 0 to 360 degrees of rotation.

Hi there..

Where is the rudder transducer located?
I would be pleased to take a couple resistance measurements

No schematics


thanks Glenn Strazds

Follow the wires from your control head to the Sailpilot and the
reference unit. They both are going to be physically attached to the
rudder quadrant but mounted to something fixed on the hull. The
reference unit is a black device that rotates as your quadrant moves.
This makes the resistance value in the leads from the reference unit
change. Disconnect them and take the resistance measurement.
