I have an Autohelm 5000
(linear drive to rudder
that has worked well until recently. The problem seems to be in the cockpit remote
control unit (company designated as Auxiliary Control Unit
). This control has two dials: Set - Duty
which connects or disables the remote
control, and Left - Right
which is a direction override to the Set heading.
I used to be able to power up the master control unit in the cabin
, then switch the control to remote, then run up to the cockpit
where I would steer to the desired course, switch the ACU from "Set" to "Duty" and let it take over.
The a/p still works fine when set at the main control down below. But now when I switch to remote the boat starts veering off in one direction. I cannot get it to stop by using either right/left control on the remote. Only turning the remote off stops the problem.
This is a new problem. I think this did not fail all at once. I had the problem suddenly late one night, but on a sail a couple weeks later it worked fine. Then a couple days after that it happened again, and has stayed faulty.
I am thinking there must be some sort of short in the ACU? I have a search set up on eBay for a used remote unit. But does anyone have any ideas here? I'm willing to tinker and splice. (Wondering if something went bad on the L-R dial? Maybe I could disable it?)
I really need to be able to turn the remote off, steer to a desired heading, and then switch it on - from the cockpit. Going below and back is a drag.
