Ignition Cable: Testing and Inspection

1. Inspect spark plug wires for signs of arcing or burning.
2. Check resistance of wires using an ohmmeter. Resistance should be:

6 K ohm for solid core wires with resistor ends
5.6 ± 1 K ohm for carbon core wires

3. If resistance is not within specifications, replace spark plug wire set.
