Ignition Coil Resistance Check
- Using an ohmmeter set to low scale, connect ohmmeter leads to positive and negative primary terminals of ignition coil. Resistance reading should be 0.75 - 0.81 ohms.
- Change ohmmeter to the x1000 scale and connect ohmmeter leads to coil negative terminal and coil tower. Resistance should be 10, 000-11, 000 ohms. If either reading is not to specifications, replace ignition coil.
