See Figure 1

IGNITER UNIT



  1. Check and service any Honda engine codes before proceeding.
  2.  
  3. Check the No. 32 50A fuse on 1985-91 models, or the No. 39 50A fuse on 1992-95 models in the dash fuse box before testing.
  4.  
  5. Remove the distributor cap, rotor and the leak cover.
  6.  
  7. Disconnect the wires from the igniter.
  8.  
  9. Turn the ignition switch ON .
  10.  
  11. Check for voltage between the BLK/YEL wire and ground. If there is no voltage check the BLK/YEL wire and ignition switch.
  12.  
  13. Check for voltage between the WHT/BLU wire and ground. If there is no voltage check the WHT/BLU wire and the ignition coil.
  14.  
  15. Check the continuity between the WHT wire and body ground. Service the wire or connectors as needed.
  16.  
  17. Check for continuity between the BLU wire and body ground. If no continuity check the wire and connectors between the igniter unit and the tachometer or the A/T control unit.
  18.  
  19. If any tests were not passed, replace the igniter unit.
  20.  
  21. Turn the ignition OFF .
  22.

IGNITION COIL



1988-89 Models

See Figure 2

  1. With ignition switch OFF , remove the distributor cap.
  2.  
  3. Remove the two screws to disconnect the BLK/YEL front terminal A and WHT/BLU from terminal B of the coil.
  4.  
  5. Using an ohmmeter, check resistance between terminals. Replace coil if resistance is not within specification.
  6.  

Resistance will vary slightly with coil temperature. Specifications are at 70°F (21°C)

  1. Check that the primary winding resistance between terminals A and B is 0.3-0.5 ohms.
  2.  
  3. Check that the secondary winding resistance between terminals A and the coil tower is 9,440-14,160 ohms.
  4.  
  5. If not within specifications, replace the coil.
  6.

  6.  

Resistance will vary slightly with coil temperature. Specifications are at 70°F (21°C)

  1. Check that the primary winding resistance between terminals A and B is 0.6-0.8 ohms.
  2.  
  3. Check that the secondary winding resistance between terminals A and the coil tower is 9760-14640 ohms.
  4.  
  5. If not within specifications, replace the coil.
  6.  

1992 Models
  1. With ignition switch OFF , remove the distributor cap, rotor and cap seal, then remove the leak cover.
  2.  
  3. Remove the two screws to disconnect the BLK/YEL front terminal A and WHT/BLU from terminal B of the coil.
  4.  
  5. Using an ohmmeter, check resistance between terminals. Replace coil if resistance is not within specification.
