TESTING



Carbureted Engines

The ignition coil should be approximately 68°F (20°C) when tested.

  1. Disconnect the negative battery cable.
  2.  
  3. Detach the lead wires and coil-to-distributor wire from the ignition coil.
  4.  
  5. Remove the ignition coil.
  6.  
  7. Using an ohmmeter, measure the primary coil resistance between the positive (+) and negative (-) coil terminals. The primary coil resistance should be 1.35-1.65 ohms.
  8.  
  9. Using an ohmmeter, measure the secondary coil resistance between the positive (+) terminal and the coil-to-distributor wire terminal (on the coil). The secondary coil resistance should be 11.0-3.5 kilohms.
  10.  

If the primary or secondary resistance is not as specified, replace the ignition coil.

  1. Install the coil, and attach all wires to it.
  2.  
  3. Connect the negative battery cable.
  4.  

TFI and MFI Engines

See Figures 1, 2, 3, 4 and 5

The ignition coil should be approximately 68°F (20°C) when tested.

  1. Disconnect the negative battery cable.
  2.  

Disconnecting the battery cable on some vehicles may interfere with the functions of the on board computer systems and may require the computer to undergo a relearning process, once the negative battery cable is disconnected.

  1. Detach the lead wire connector and coil-to-distributor wire from the ignition coil.
  2.

Fig. Fig. 3: The ohmmeter should be connected to the terminals shown for ignition coil testing-1996-98 models

  1. Using an ohmmeter, measure the primary coil resistance between the positive (+) and negative (-) coil terminals. The primary coil resistance should be as follows:

    1.3L engines-0.9-1.1 ohms
     
    1989-93 1.6L engines-0.72-0.88 ohms
     
    1994-95 1.6L engines-1.08-1.32 ohms
     
    1996-98 1.6L engines-0.7-0.9 ohms
     

  2.  
  3. Using an ohmmeter, measure the secondary coil resistance between the positive (+) terminal and the coil-to-distributor wire terminal (on the coil). The secondary coil resistance should be as follows:

    1.3L engines-10.2-2.8 kilohms
     
    1989-93 1.6L engines-10.2-3.0 kilohms
     
    1994-95 1.6L engines-22.1-29.9 kilohms
     
    1996-98 1.6L engines-2-18 kilohms

Fig. Fig. 5: For 1989-95 fuel-injected Sidekick and Tracker models, attach the ohmmeter to the ignition coil as shown for secondary circuit testing

If the primary or secondary resistance is not as specified, replace the ignition coil.

  1. Install the coil, and reattach all wires to it.
  2.  
  3. Connect the negative battery cable.

REMOVAL & INSTALLATION



Carbureted Engines
  1. Disconect the negative battery cable.
  2.  
  3. Label and detach the positive and negative lead wires from the ignition coil by loosening the wire terminal securing screws.
  4.  
  5. Detach the high-tension coil-to-distributor wire from the ignition coil by grasping the wire BOOT with your fingers and pulling it off of the terminal tower.
  6.  


WARNING
Whenever disconnecting spark plug or coil-to-distributor high-tension wires, always pull on the boot. If you pull on the wire itself, the metal terminal inside the boot may become detached from the wire, requiring you to purchase a new wire.

  1. While supporting the ignition coil, remove its two mounting fasteners, then remove the coil from the engine compartment.
  2.  

To install:
  1. Position the ignition coil in the engine compartment so that the mounting fastener holes are aligned with the coil mounting bracket slots.
  2.  
  3. Install and tighten the two coil mounting fasteners until secure.
  4.  
  5. Reattach the high-tension coil-to-distributor wire; be sure that the wire is fully engaged on the ignition coil terminal tower.
  6.  
  7. Reattach the positive and negative lead wires to the coil and tighten the wire terminal securing screws snugly.
  8.  
  9. Connect the negative battery cable.
  10.  

TFI and MFI Engines

See Figure 6, 7 and 8

Disconnecting the battery cable on some vehicles may interfere with the functions of the on board computer systems and may require the computer to undergo a relearning process, once the negative battery cable is disconnected.

  1. Disconect the negative battery cable.
  2.  
  3. Label and detach the lead wire connector from the ignition coil by disengaging the connector retaining tab.
  4.  
  5. Detach the high-tension coil-to-distributor wire from the ignition coil by grasping the wire BOOT with your fingers and pulling it off of the terminal tower.
