Mazda 323 Ignition Coil
The part that increases the 12 volts from the battery to tens of thousands is the Mazda 323 Ignition Coil that enables a spark to jump the plug gap and ignite the mixture of fuel and air. The shell is made of plastic or epoxy, inside of which is an iron core, a heavy primary winding, and a much finer secondary winding. As the current passes across the primary side, a magnetic field is generated, and the moment the ECU or breaker points are opened the field collapses and forces a surge of current into the secondary winding, which is 15,000 to 40,000 volts; the energy then passes through the high tension lead or directly to the plug. Early Mazda hatchbacks applied a single coil to energize a distributor, thus a single voltage path was applied by all the cylinders. The design was modified later to an Ignition Coil pack on subsequent models of the 323 which accommodated two or more coils, emitting paired sparks in a waste spark pattern and reducing the part count. New versions of Mazda have Coil-on-Plug units that can be found immediately above each spark plug, which shorten the path the charge takes and eliminate the use of long wires. Coil packs and COP designs reduce energy losses, enhance idle quality, and reduce the risk of misfire compared to the older design due to the smaller number of plugs served per Ignition Coil and the lower heat exchange. It may still overwork any Mazda coil with age, high resistance, and widened plug gaps, still causing rough running, but rapid resistance checks or scope traces will diagnose the weak Ignition Coil before performance declines.

Mazda 323 Ignition Coil Parts and Q&A
- Q: What steps should be taken to check the ignition system and replace ignition coils on Mazda 323?A:Check ignition system by cranking the engine and also a strong blue spark at the coil or at the spark plug wire. On models since the year 1994, with no spark, unplug the connector to the ignition coil and confirm that there is a battery voltage on the positive terminal with the ignition switch on. In case of zero voltage, check the main fuse, ignition switch and wiring harness. Test the primary coil winding resistance using an ohmmeter, if out of specification replace coil. Measure Coil winding resistance of secondary coil. Likewise, replace coil in case of need. In 1995-1998 models, do ignition system tests and remove the 3-pin connector off distributor, on 1995 models and 1996 1.5L DOHC California models. Check the primary and secondary coil resistances; substitute the distributor where above specifications. To check the resistances of the 1996 models (except 1.5L DOHC California) and all 1997 models, remove the 7-pin connector and measure resistances as above, as required, changing the distributor. To 1999 and subsequent models, disconnect the fuel pump relay and test secondary spark with a spark tester on the plug wires. Measure resistance on both coil-packs and change on test failure. Depending on the model, the coil replacement may be different; 1994 and older be replace the coil, 1995-1998 replace the entire distributor (distributor assembly), unbolt and disconnect coil-packs (1999) and 1999-2001 and 2001-2003 (1.6L and 2.0L, respectively) have all coils mounted to spark plugs. Disconnect the negative battery cable, take off the heat shield, label and remove wires off the coil terminals, and take off mounting screws. In the case of 1.6L and 2.0L DOHC engines, lift the coil carefully in an upright position to prevent damages. Removal is reversed in order to be installed.
