- When disconnecting the tip of the high-voltage wire from the spark plug, do not pull on the wire, but only on the tip, while turning the tip half a turn in one direction and the other.
- Check for cracks or damage to the wire and cap insulation.
- Measure the resistance of all high voltage wires, which should not exceed 22 kOhm (pic. 9.4)
