Ignition coil — checking and replacement (Mazda Capella GE)

Examination

Ignition systems with a distributor

1. Check that the ignition is off.

2. Disconnect the ignition coil connector and check the resistance of the primary winding: on 1993 and 1994 models, check the resistance between terminals A and C; on 1995-1997 models, check the resistance between terminals A and B.

3. Check the resistance of the ignition coil secondary winding: On 1993 and 1994 models, check the resistance between terminal C and the high tension wire terminal; on 1995-1997 models, check the resistance between terminal A and the high voltage wire terminal.

4. Replace the ignition coil if necessary.

5. Disconnect the connector connecting the primary windings of the coil. Measure the resistance between the negative terminal and each of the positive terminals.

6. Label the high voltage wires and disconnect them from the coil. Check the resistance between pairs of terminals: On 4-cylinder models, check the resistance between the upper and lower pairs of terminals; on 6-cylinder models, check the resistance between terminal pairs A–B, C–D, and E–F.

7. Replace the coil if necessary.

Replacement

Ignition systems with a distributor

1. Disconnect the negative battery cable.

2. If the ignition coil is integrated into the ignition distributor, the distributor must be replaced.

3. To replace the external ignition coil, disconnect the connection connectors from the coil, unscrew the mounting nuts and remove the coil.

4. Installation is carried out in the reverse order of removal.
