2. If the engine will not start due to moisture on the high voltage wires or in the distributor cap, a dispersant can be used to absorb the moisture.
Low voltage circuit
3. See procedures given in Chapters 6, 8 or 10.
High voltage circuit
4. Damage to the high voltage circuit will be limited to the spark plugs, high voltage wires, distributor breaker cover, distributor runner or ignition coil.
5. Disconnect the high voltage wire from the spark plug and connect it to a spare spark plug securely pressed against the cylinder head. The replacement spark plug must be in good condition and, if necessary, can be grounded to the cylinder head or a suitable grounding point. It is not desirable to keep the high voltage wires close to the head, as this may damage the electronic ignition components.
6. Turning the engine over quickly with the starter, check for a good spark at the spark plug. Do not repeat this procedure on models equipped with a catalytic converter.
7. Connect the high voltage wire and repeat the test on the remaining spark plugs.
8. If there is a good spark on all cylinders, remove the spark plugs, clean or replace them.
9. If there is no ignition spark at all, check the high voltage wires. Also check the ignition coil and distributor cap.
10. Remove the switch-distributor cover, check the wear of the surface between the high-voltage parts (internal and external). Replace cap if necessary.
11. Check the distributor slider in the same way. Note that the distributor runner on the 7A engine is attached to the drive shaft and cannot be replaced.
12. Check the carbon brush in the cover of the breaker-distributor.
13. Clean the carbon deposits in the cover of the breaker-distributor and on the segments of the distributor slider, but do not remove the metal.
14. Install the distributor slider and the cover of the breaker-distributor, connect the high voltage wires.
