| Subject: | FW: Autopilot Problem |
I am looking for advice on how to troubleshoot the following problem with m
y autopilot. My setup is as follows. I have a King KCS-55A Compass system
with the KI-525A HSI indicator. This is coupled to an STEC 60-2 autopilot
. Also connected to the HSI is a King KX-165 and Northstar M3 Approach GPS
.
The problem=2C which happened during my last flight is=3B when the autopilo
t in set to the heading mode=2C it will not track to the bug setting=2C it
will either roll to the left or right all the way to the aileron stops. Th
e closer it is the bug setting the slower the roll and just about stops at
the bug. The same thing appears to happen in the NAV mode when driven by t
he VOR or GPS.
I have checked and reseated all connections on the turn coordinator=2C auto
pilot controller=2C roll computer and HSI with no luck.
Thanks for the advice.

Mike,
Same issue as what I'm having with my S-Tec System 30 except it is only to the
left.
S-Tec told me to check the outputs of my HSI (Century NSD1000) to match +- 5VDC
depending on which side of the bug you're on. Haven't been able to do that as
my GPSS module crapped out and I had to sent it in for repairs - it's back and
I haven't had time to test it again.....
I need to test that and the alt hold module - in case I need to reverse pins 3
and 4.....
Check with S-Tec about what the specs should be for your King HSI...
Let me know what you come up with...
Ralph

That sounds like a polarity reverse. Rather than going through all the
block connections why not just reverse the polarity of the aileron actuator
motor... Be sure to mark this change on your block interconnect diagram if
you made one.

The further you are off course the more deviation goes to the controller and
the more power is fed to the aileron actuator. The problem is your aileron
actuator is going the wrong way this can only be because either the inputs
to the controller from the HSI are reversed or the power wires to the
aileron actuator are reversed. One, not both, of these things are the
problem. I recommended reversing the power wires to the actuator forgetting
that most of the planes on this list are certified. For a certified plane
triple check the polarity of the controller inputs from the HSI to the
autopilot controller. If that is perfect, then reverse the polarity of the
two wires going into the aileron actuator. Do not change any other wiring (
assuming everything else works properly).

Woops.... if this only happens ONLY when the heading hold is selected then
the output from the HSI to the autopilot controller must be reversed. If
the auto pilot always reverses the correct input then the actuator wires are
reversed.

BTW did you draw up an interconnect diagram and can you scan it so we can
see what/how you have your system installed.
