Ignition Coil Wire: Testing and Inspection

Testing Coil Wire:

1. Remove coil wire.
2. Check wire visually for cracks, rub marks, oil saturation and corrosion at terminals. Replace if needed.
3. Measure overall resistance of wire. Reading should be between:

1200 - 2800 ohms

If reading is correct, coil wire is good, move to step 4.
If reading is incorrect, measure resistance at the two connectors. Reading should be between:

600 - 1400 ohms

If reading is incorrect, replace and retest with new connector(s).
If reading is correct, replace and retest with new wire.
4. Reinstall coil wire.
