3. SPARK PLUG WIRES

The high voltage or spark plug wire conveys the high-voltage impulse produced by the coil to the spark plug.
The spark plug generates the spark between its electrodes. For proper operation, the contacts between the
high-voltage wire from the coil and the high-voltage wire to the spark plug must be perfect.
During the inspection according to the maintenance guidelines, check the following before fitting new wires into
the engine:
The condition of the connection between the high voltage wire and the coil, removing sulphated
-
compounds if any.
- The tightening torque of the coil fixing screws in the event of a screwed coupling.
- The resistance of the high voltage wire is 5k; therefore, it must be in the range of 4 to 6k.
Otherwise, change the wire for a new one.
