Autopilot Servo

You should be able to turn on master, pull knob and turn the knob left or right in which the ailerons should follow. The servo motor should operate incrementally. When AP is on you should not be able to turn the yoke. This is a manual overide and has nothing to do with the AI. The autopilot has feedback from the attitude indicator and turn info from the heading select bug on the DG. This test is basically putting a correction voltage from the pot directly to the servo. The outer ring is used to compensate for fuel load or trim and centres the should be trimmed so the heading bug aligns with top dead centre.

fyi
