The ignition coil is an integral component of the distributor assembly.
Prior to testing the coil, perform a secondary spark test. If spark occurs at the spark plug, the coil is functioning properly.
- Turn the ignition OFF .
- Disconnect the negative battery cable. On the Cirrus, Stratus and Sebring convertible models, disconnect the remote negative battery cable connection on the left strut tower.
- Disconnect the 2-pin electrical harness from the distributor.
- Inspect the harness connector and ignition coil terminals for dirt, corrosion or damage. Repair as necessary.
It may be necessary to use jumper wires for testing access to the terminals.
- Using an ohmmeter, measure coil primary resistance between the terminals of the 2-pin connector on the distributor. Resistance should be 0.6-0.8 ohms.
- Measure coil secondary resistance between the ignition coil tower and one terminal of the 2-pin connector on the distributor. Then, measure coil secondary resistance between the ignition coil tower and the other terminal of the 2-pin connector on the distributor. Resistance should be 12-18 kilohms.
- If resistance is not within specifications, the coil may be faulty.
REMOVAL & INSTALLATION
The ignition coil for the 2.5L engine is located in the distributor housing. If the ignition coil is defective, the distributor assembly must be replaced. Refer to Distributor removal and installation.
