Ignition Coil Resistance
- Connect ohmmeter leads to positive and negative terminals of ignition coil. Ignition switch should be "OFF" and wire should be removed from positive terminal of ignition coil to isolate it from system. Primary resistance should be 0.70-0.85 ohm.
- With ignition switch still "OFF", connect ohmmeter leads to coil negative terminal and coil tower terminal. Secondary resistance should read 9,000-11,000 ohms.
- If either reading is not within specified range, replace ignition coil.
