Trouble Shooting
- Set brakes. Place transmission in Neutral or Park. Start engine. If cruise control engages when engine is started, or does not disengage when brake pedal is depressed, electrical circuit is faulty.
- Release brakes and accelerate vehicle to desired speed. If cruise control engages without actuating "SET" button, electrical circuit or switch is faulty.
- Depress and release "SET" button. Remove foot from accelerator. Speed should be controlled. If speed setting is too high or low, electrical circuit is faulty or system has a vacuum leak.
- If there is no speed control when button is pressed, sensor is faulty, fuse is blown, system has a vacuum leak, cable is disconnected, electrical circuit is faulty, or speed control switch is improperly adjusted.
- If there is speedometer noise, excessive needle waver, or erratic servo lock-in performance, speedometer cable is damaged, cable core is bent or too long, speedometer head is noisy, or the cable ferrule nut is loose at the speedometer head, transmission or control servo.
- Drive the vehicle over a rough road. If unit disengages, brake light and speed control switch adjustment is incorrect. Tap brake pedal lightly. If there is no disengagement of system, brake light and cruise control switch adjustment is incorrect, cruise control chain is damaged, or electrical circuit is faulty.
- If in step 6 carburetor does not return to idle, cruise control chain is damaged, misadjusted, or throttle linkage is faulty. If in step 6 cruise control disengaged, depress "RESUME" button. Vehicle should resume previous speed.
- If there is no resume when button is depressed, switch or electrical circuit is faulty. If vehicle resumes speed, cruise control is okay. If resume speed is possible below 25 MPH, electrical circuit is faulty.
