Ignition Coil: Testing and Inspection

Checking Primary Resistance:

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

Primary resistance:
0.3 - 0.6 ohms at -10 - +40°C (14 104°F)

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

Checking Secondary Resistance:

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

Secondary resistance:
9 - 15 k ohms at -10 - +40°C (14 - 104°F)

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