Ignition Coil Resistance Check
Using an ohmmeter set to low scale, connect ohmmeter leads to ignition coil primary terminals No. 1 and No. 15. Take reading. Connect ohmmeter leads (set to x1000 scale) to negative terminal No. 1 and coil tower terminal No. 4. Take reading. If ohmmeter reading is not within specifications, replace ignition coil. See IGNITION COIL RESISTANCE SPECIFICATIONS table .
