Servo Assembly

NOTE: If Orange/Yellow lead is shorted to either White/Pink or Gray/Black leads, it may be necessary to replace amplifier.
  1. Separate servo-to-amplifier 8-pin connector. Connect an ohmmeter between Orange/Yellow and Gray/Black wires at servo connector. Resistance should be 40-125 ohms.
  2. Connect ohmmeter between Orange/Yellow and White/Pink wires. Resistance reading 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.
  4. Servo throttle actuator arm should pull in and engine speed should increase. Arm should hold this position or slowly release. If White/Pink wire is removed from ground, servo should release immediately.
