Ignition Cable: Testing and Inspection


NOTE: Never stick a needle or the pointed end of a probe into the cable. An increase in resistance would be created which would cause the cable to become defective.




1. If the cable has broken or cracked insulation, it must be replaced.
2. If the terminals are corroded or loose, the cable must be replaced.
3. Check the cable resistance with an ohmmeter. Replace the cable if resistance exceeds 22.4 k-ohms.
