Ignition Coil: Testing and Inspection

Checking Coil Primary Resistance:





Inspect Primary Coil Resistance
- Using an ohmmeter, measure the resistance between positive (+) and negative (-) terminals.

Primary coil resistance (Cold): 1.1 - 1.7 ohms

- If the resistance is not as specified, replace the ignition coil.

Checking Coil Secondary Resistance:





Inspect Secondary Coil Resistance
- Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.

Secondary coil resistance (Cold): 9 - 15 k ohms

- If the resistance is not as specified, replace the ignition coil.
