Primary Tests
Ignition Coil:
Coil Schematic Diagram:
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 - B:
Resistance value
0.6 - 0.8 ohms
3. Using an ohmmeter, measure for continuity between the terminals A - B. If no continuity, replace coil.
4. Using an ohmmeter, measure resistance between the terminal A - secondary windings:
Resistance value
14,000 - 22,000 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)
