Ignition Coil Resistance (Externally Mounted)

Remove coil connectors and secondary coil wire. In test "A", use high ohmmeter scale. Resistance value should be very high (infinite). See Fig 1. If not, replace coil.
In test "B", use low ohmmeter scale. Reading should be very low or near zero ohms. If not, replace coil. In test "C", use high ohmmeter scale. See Fig 1. If there is no continuity, replace coil.
