Default Autohelm 5000 Boat going in circles

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

Did it ever work for you, correctly? If not, then first thing I would
check is to see, if the controller to actuator wiring is hooked up
backwards. Ie controller says turn right and actuator is turning left.
This happens alot more often than one would think, with consumer
installations.

Autohelm 5000 Boat going in circles; Hunter 40

Hi there I thought I should ask this group; members with an Autohelm 5000
that have experienced their boat going in circles while endevoring to
make
the autopilot work and what they did to get it to do what it i ssuposed
to
do....

Is the controller defective? a nor and gate needs replacement? The
fluxgate
compass is close to a magnetic article?

Followed the owners manual for setting it up ?

Pondering replacement - Navman system to go with the 3100 series
instruments
already purchased and sent back for warranty - which do work well
otherwise
including nema

Thanks Glenn Strazds
