I can't find that file on this computer and it should be on another that is
not on line right now. I will try to recover that file and post it for you
in the next couple days.

Google told me that Steve of "Good Intentions" appears to have once
had old Autohelm schematics. I have a working tiller pilot that
strongly resembles the one in this manual

http://www.raymarine.com/raymarine/S...H800Analog.pdf

and I have a second one in superficially better shape that isn't
working and has the sound of small pieces moving inside the casing.

So my plan is to fix the non-working one, or scavenge parts. The best
way to do either is with a schematic. So if anyone can guide me to
one...

One puzzle is that I could have sworn the units were called Autohelm
1000s. They are pre-interface with anything, and work simply with an
"off/calm/rough/vane" switch, and a compass heading dial. But the
AH1000 manual on the Raymarine site shows a push-button (more recent)
model, with the only "dial" tiller pilot being the AH800. Mine has the
standard two-pin 12 v plug and mounts on the starboard locker top and
just "sits" on a pin on top of my tiller, around the mid-point. It
works so well that I see no need to change it, particularly if I can
revive or scavenge its twin, disposed at the "free stuff" locker at my
boat club.

So hailing Steve, or anyone with a lead on how to troubleshoot these
old machines.

TIA,
R.
