Ignition Coil Resistance
- Connect ohmmeter leads to positive and negative terminals of ignition coil. Ignition switch should be off and coil positive terminal wire removed 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 to specification, replace ignition coil.
