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