Ignition Coil Resistance Test

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