Ignition Coil Resistance

Disconnect electrical connector and distributor wire from ignition coil. To measure primary resistance, measure resistance between terminals of ignition coil electrical connector. See COMPONENT LOCATIONS  under INTRODUCTION. To measure secondary resistance, measure resistance between Black/Orange wire terminal of ignition coil electrical connector and coil secondary tower. If resistance is not as specified, replace ignition coil. See IGNITION COIL RESISTANCE  table.
