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.

Fig 1: Ohmmeter Hookup for Making Ignition Coil Resistance Tests Be sure ignition is off and coil wires are disconnected before making this test.
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.
