Yes, it is a Bendix/King KCS-55A HSI. No...it does not work, even on the ground or in flight - only when the knob "slave - free" is switched and back again. As you can read, the german avionic Company tried to replace "everything"...but all units in the Mooney are working correctly....there is not the Problem...and -> this is the Problem!....we don't know how to proceed...

Hello Mooney Aviators, I have a avionic problem with my Mooney 201, D-EMOA, and want to ask our community, whether anyone knows/had that problem too and could give me a fitting solution. The gyro compass in my Mooney does not follow the heading when the plane is turning - unimportant if it is moving on the ground or in flight. The EMOA is IFR-equipped and when I change the switch "Slaved - Free" from slaved to free and back the gyro compass gets the right heading but does not follow when the plane is turning again. A leading german avionic company tried to fix the problem for 5 weeks now - not successfull. They told me, that they replaced every important part...the compass, the switch, the flux valve transmitter, the main compass in the stern...cleaned all the contacts...-> no success until today... Now I am asked to fly the plane to the HQ of the avionic company for "further attempts to solve the problem"... ->-> Has anyone of you had this problem,too...? or an idea what the reason of the problem could be?...and what I could do to fix it very soon now?... Thank you all!....
