See Figure 1
- Disengage the wire(s) from the coil.
- Use an ohmmeter, connected as illustrated, to measure the resistance on the primary side of the coil; the resistance should be 0.8-1.6 ohms.
- Use an ohmmeter, connected as illustrated, to measure the resistance on the secondary side of the coil; as illustrated. the resistance should be 6-30 kilohms.
- If the resistance readings are not within specifications the coil is defective and must be replaced.
- If resistance readings are within specifications, there may be a larger problem with the EEC system. It may be necessary to have the system further tested (because of the extensive experience and knowledge necessary, and equipment to perform this testing) by a professional automotive technician.
REMOVAL & INSTALLATION
See Figure 2
- Disconnect the negative battery cable.
- Disengage the ignition connector and coil wire from the coil.
- Loosen the ignition coil mounting nuts and remove the coil and bracket.
- If removed, install the bracket to the ignition coil.
- Place the ignition coil and bracket into its mounting position and tighten the mounting nuts.
- Engage the ignition connector and coil wire to the coil.
- Connect the negative battery cable.
