Camplate notch lags the bolt position indicator arrow by 90 degrees.
Use hand crank to manually rotate gun until bolt position indicator is pointing 1/4-in. before COOKOFF ZONE (cross-hatched area). While performing resistance check between pins L & M on motor/turret plug, have helper look through bolt position indicator glass and hand crank gun slowly until the actuator roller falls into the camplate notch. Did a reading of less than 0.5 ohms occur when roller fell into the camplate notch?
