This one was a difficult one. NAC3 autopilot computer is showing error "clutch overload". Although I was able to fix that kind of problems, this one was more specific.
I have been strugling for hours to draw some kind of schematics (a few parts are missing in schematics) trying to figure out how microcontroller monitors current passing through clutch. It is monitoring through op amps connected in series, and when I changed faulty op-amp problem seemed to dissapear. But during the load testing "clutch overload" error would come up somethimes. I figured out that one of the resistors was out of spec value. Good thing I have working NAC3 so I could compare values, without it it would be almoust impossible to solve this kind of problem.
