Servo Assembly

CAUTION: If Orange-Yellow lead is shorted to either White-Pink or Grey-Black leads it may be necessary to replace the amplifier.
  1. Separate servo-to-amplifier connector. Connect an ohmmeter between Orange-Yellow and Grey-Black wires at servo connector. Resistance should be 40-125 ohms.
  2. Connect ohmmeter between Orange-Yellow and White-Pink wire leads. Resistance should be 60-190 ohms.
  3. Start engine. Connect Orange-Yellow lead of servo connector to battery positive post and White-Pink lead of servo connector to ground. Momentarily touch Grey-Black lead of servo connector to ground. Servo throttle actuator arm should pull in and the engine speed should increase. The arm should hold this position or slowly release. If White-Pink wire is removed from ground, servo should release immediately.
