Yes No Prior to starting engine: Disconnect electrical connector from controller. Disconnect the linkage, bead chain or With an ohmmeter probe connector Cavity "J ** cable from servo to throttle. (circuit 150) to known good ground. Make sure the electrical connector to Measure the resistance. the servo is still disconnected. Start the engine and let it idle. Does resistance measure 0 ohms? No Yes Manually actuate the servo vent and vacuum control valves by connecting Find open in circuit 150 (Pin "J" of Find open in circuit 150 (Pin ""C" of jumper wires from Positive ( + ) Battery controller to ground Point G150), Post to Pins ""A" and ""E"" on the servo servo to splice $260) · See Schematic See Schematic assembly. With another jumper wire connect one end to Pin "C"" on the servo and the other end to a known good ground. Repair or Replace as required. Repair or Replace as required. With the brake (and clutch) pedal in free position, does the servo pull in full stroke? No Yes Remove the larger of the 2 hoses to the servo and Remove jumper wire from Pin "E"" on servo. plug the now open fitting (orifice) on the servo. Does servo stay at full stroke?
