DIAGNOSTIC PROCEDURE

COMPONENT INSPECTION
Ignition wires
1. Inspect wires for cracks, damage, burned terminals and for improper fit.




2. Measure the resistance of wires to their distributor cap terminal. Move each wire while testing to check for intermittent breaks.

Resistance: 13.6 - 18.4 K Ohms/m (4.15 - 5.61 K Ohms/ft) at 25°C (77°F)

If the resistance exceeds the above specification, inspect ignition wire to distributor cap connection. Clean connection or replace the ignition wire with a new one.
