Ignition Coil: Testing and Inspection

- Disconnect harness connector and coil wire.
- Measure resistance between positive (+) and negative (-) coil terminals.
Resistance should be 1.2 - 1.4 ohms

- Measure resistance between secondary and negative (-) coil terminals.
Resistance should be 8600 - 13000 ohms

- Measure resistance between coil insulation and all terminals.
Resistance should be more than 10 M ohms

- Replace coil if not as specified.
