REFLECTOR: BMA Autopilot

[Brett Ferrell]

Yes, I had this exact experience, and my was busted.  Did you use BMA cables or did you build your own?  I built mine, and they recommended that I try a standard DB9 serial cable.  It can't carry quite the needed current, but will prove that the wiring is correct, and that the controller is bad.  I sent mine back to BMA, and they repaired it and returned it within a week, now it just clicks once when I power it up, and and clicks when engaged.  If I engage it and change heading, it steps up gradually just like the manual says.

  Anyone out there with Blue Mountain Avionics Autopilot experience?  I tried engaging for the first time today and the servos came to life as soon as I applied power to the controller, which is in direct conflict with the book.  It says it shouldn't do anything until you "engage" it.  When I do try "engaging" it, the servos just jump around, and the display flashes "DISENGAGE".  I have a EFIS LIte with 2.23 software.  This was all on the ground, although it does the same thing in flight also.  Any suggestions?
