Ignition Coil: Testing and Inspection
Primary Tests
Coil
1.
With the ignition switch OFF, disconnect the primary wire connector and the coil wire.
2.
Using an ohmmeter, measure resistance between the terminals A - D:
Resistance value
0.3 - 0.4 ohms
3.
Using an ohmmeter, measure resistance between the terminals B - D:
Resistance value
2.09k - 2.31k ohms
4.
Using an ohmmeter, measure resistance between the terminal A - secondary windings:
Resistance value
9.04k - 13.56k ohms
5.
If ignition coil fails any of the above tests replace ignition coil
NOTE: Resistance will vary with the coil temperature, specifications are at 68°F (20°C)
