TESTING



4-Cylinder Models
  1. Place the ignition switch in the OFF position.
  2.  
  3. Disconnect the ignition coil terminals.
  4.  
  5. Using a suitable ohmmeter, measure the pick-up coil resistance between the pick-up coil terminals.
  6.  
  7. The standard resistance should be 140-180 ohms. If the resistance is not within specification, check the wiring and connectors. Replace the pick-up coil if defective.

  1. Disconnect the pick-up coil wiring.
  2.  
  3. Switch the ohmmeter to the middle ohms scale.
  4.  
  5. Measure the coil resistance between either of the pick-up coil leads and the housing. Infinite resistance should be read.
  6.  
  7. Connect the ohmmeter probes across the coil leads and measure the resistance. It should read 500-1000 ohms. Flex the lead wires at the coil and connector by hand to check for intermittent opens in the wiring.
  8.  
  9. If the resistance readings are not within specifications, replace the coil.

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the distributor cap, with the spark plug wires attached, and place aside. Remove the rotor cap.
  4.  
  5. Unfasten the harness attached to the distributor and pick-up coil.
  6.  
  7. Remove the pick-up coil retainer. Unfasten the pick-up coil wire harness plastic connector at the side of the distributor. Slide the pick-up coil off the distributor shaft.
  8.  

To install:
  1. Lubricate the distributor shaft lightly with oil. Slide the pick-up coil down the shaft and position in place. Install the pick-up coil retainer clip to secure the coil in place.
  2.  
  3. Attach the wire harness to the side of the distributor body, making sure none of the wires could get caught in the distributor while it rotates.
  4.  
  5. Attach the wire harness to the distributor and pick-up coil.
  6.  
  7. Install the rotor and distributor cap.
  8.  
  9. Connect the negative battery cable.
  10.  
  11. Check for proper vehicle operation.
