Ignition Coil: Testing and Inspection

Ignition Coil Test

1. Turn the ignition switch OFF.




2. Disconnect the 3P connector and the ignition coil wire.




3. 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; specifications are at 68°F (20°C)

Primary Winding Resistance
(Between the terminals 1 and 3):
0.34-0.42 Ohm

Secondary Winding Resistance
(Between terminal 2 and secondary winding terminal):
17.1 - 20.9 k Ohm
