Ignition Coil Test
1. With the ignition switch OFF, remove the ignition
coil.
2. Using an ohmmeter, measure resistance between
the terminals. Replace the coil if the resistance is
not within specifications.
NOTE: Resistance will vary with the coil
temperature; specification is at 77°F (25°C).
Primary Winding Resistance
(Between the A and B terminals): 0.9—1.1 ohms
3. If primary winding resistance is OK, substitute a
known-good ignition coil, and check the system
operation.
If the system is normal, replace the original ignition
coil.
