Ignition Coil Resistance (MX-3 1.8L)

Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between terminals "A" and "B" of coil. See Fig 3 . Resistance should be as specified in IGNITION COIL RESISTANCE table. If resistance is not as specified, replace ignition coil.
Check secondary resistance between terminal "A" and coil tower. See Fig 3 . See IGNITION COIL RESISTANCE table. If resistance is not within specification, replace coil.
