CAUTION: Carefully remove the Ignition Wires by pulling on the Rubber Boots. Do not bend the Wires; you might break them inside.





1. Check the condition of the Wire Terminals. If any Terminal is corroded, clean it, and if it is broken or distorted, replace the Wire.





2. Connect Ohmmeter Probes and measure resistance.
3. If resistance exceeds 25 K Ohms replace the Ignition Wire.

Ignition Wire Resistance: 25 K Ohms max. at 68°F (20°C).
