Ignition Coil Resistance Test
- Connect ohmmeter set in low scale to coil primary (positive and negative) terminals. Resistance should be .48-.61 ohm. See Fig 1.
- Connect ohmmeter set in the x1000 scale to positive coil terminal and its secondary tower. Reading should be 9,000-11,000 ohms. If either reading is not to specification, replace ignition coil.
