Speed (Cruise) Control Servo
- Turn ignition switch and speed control switch to ON position. Using a voltmeter, connect negative lead to a good chassis ground. Disconnect speed control servo 4-pin connector. Measure voltage at servo harness connector terminal No. 3 (Dark Blue/Red). See Fig 1
. Battery voltage should be present when brake pedal is released and not present when brake pedal is depressed. If battery voltage is not present with brake pedal released, check for loose connections, check brake switch adjustment, or repair circuit as necessary.
- If battery voltage is present with the brake pedal released, connect a jumper wire between servo harness connector terminal No. 3 (Dark Blue/Red wire) and speed control servo terminal No. 3. See Fig 1
. Battery voltage should be present at servo's 3 remaining terminals. If battery voltage is not present, replace servo.
- If battery voltage is present, turn ignition off. Connect one lead of ohmmeter to good chassis ground. Using other lead, probe servo harness connector terminal No. 4 (Black wire). See Fig 1
. If no continuity exists, repair open in Black wire (ground circuit). If continuity exists, test is complete.
