king 200 autopilot/garmin 430 problem

[dham1956]

I have a Mooney 231 with a king 200 autopilot and garmin 430. When in coupled nav mode the cdi deviation needle is always consistently delected a few needle widths to the right. same with approaches. I went through the config process of showing the garmin where 150 degrees is with no improvement. Any ideas?

The problem is likely related to the 200 AP NAV/CDI centering adjustment. I can also be related to dirty contacts on the AP connector NAV input pins. Try contact cleaner first.

I wish I could look at it in the shop but the fact that your GNS430 deviation display matches the HSI tells me something is wrong with the 430. the 430 puts out what ever information you see on it to the HSI then the HSI sends that info to the AP. I think you have an issue with the 430.

Aside from the AP issue check the oil pressure. It is a little bit on the low side. Low oil pressure readings are related to:

 

Low oil amount

Over 50 hrs on the oil

Oil temp too high

Pressure relieve valve setting or stuck

Bearings wear

Time for an overhaul.
