3389T is a 112A serial#224. the flap indicator shows 10" of flaps when they are all the way up. the flap indicator guage is a stewart warner and was rebuilt 6 mos ago. that did not fix the problem. I removed the position transmitter from under the rear seat, and cleaned it up and noticed that where the shaft runs over the coils there is a grove. i'm sure this is the problem. Commander does not carry them, and general aviation will send them out for rebuild. anyone have any spares or thoughts?? thanks vince
