autohelm 4000 schematic

[sailoroffortune]

I started a new topic becuase the other one started in early 2000's

MY autohelm 4000 is not working and Raymarine does not support a 1986 vintage so I am looking for a schematic to repair it myself and help if anyone is familiar with this item
Logic seems to work in that red indicator lamp shows correctly in auto and standby mode and unit beeps as expected when power is applied.
drive motor turns in both directions when voltage is allpied.
supply voltages are ok but no voltages are present at drive out
put cable.

sailoroffortune thank you

Thank you anyway

I was able to get a schemaulkhead connector were tic from Raymarine
and then figured out to make a LED display to tell if I had the
correct out put which luckily I did .I then figured that the connectors both in line going to the motor and the bulkhead were
corroded.


I replaced them and it all works very nice now
