KFC 200 will not engage

Recommended Posts

Hello all. 

 

On the way back from OSH, my autopilot will not engage. From my reading, the panel switch is magnetic. Mine will not stay in up position. Panel fuse operates normally and makes no difference. 

 

Is there an inline fuse somewhere?  Anyone have a wiring diagram? 

 

Trim works fine. 

 

tks

There’s no other fuse. Did it pass self test? Does the flight director work?

Expect when the BK AP starts up... it does a self test...

the celebration of a good self test is the light and sound show... beep, beep, beep (about five or so) with a blinking light to match...

This is based on fuzzy memory of a KAP150... slightly newer than the KFC200...

It has a test protocol of all the servos, computer, and the trim servo is the one that often gets forgotten...

 

If the trim servo CB has been shut off, the test fails, no light and sound show is given, and the AP sits there and does nothing...

PP thoughts only, stuff I learned by reading the KAP book a while back...

Best regards,

Thought I remembered seeing a similar post about a year ago.  Found the post I remembered. But not totally your issue but mat help in troubleshooting. Also I highly recommend calling Autopilot Central.  They will troubleshoot over the phone with you - walk you through the steps then provide a recommendation.

Just went through the same thing. Contact Bob Weber at webairconsulting.com

It’s a fairly easy and cheap to fix if it is the same problem as mine. The clue is that the autopilot works if you hold the switch in the on position but it won’t magnetically latch in place. Bob can talk you or your hangar fairy through it.

Fixed. The same problem as Mark. The magnet on the On-Off arm had slipped out of it's socket. Two cent fix. Big clue for the future is if your On-Off switch does not seem to travel like it used to, there could be something blocking it. Like the magnet. Whew!

 

For you more experienced should I post this fix as a new post? I'd hate to see anyone pay loads of money for a loose magnet. 

 

Thanks to all.

Nice work!

You can edit the title a bit if you want...

Great solution to a vexing challenge.

One other challenge...

I can’t see the video.

It is easy to share videos using YouTube, then post a link here...

Best regards,
