PROCEDURE:
– Check that the engine is not hot. We recommend
performing the assembly minimum
0.5 hours after the engine is switched off.
– Check that the ICU control unit is not on
(the indicator is not on or flashing)!
CONNECTING THE MOUNTING TOOL FOR SPARK PLUG TESTING
1) Remove the boot holder from the spark plug
boot and remove the boot.
2) Screw the spark plug out using a spark plug
spanner. Check the spark plug and possibly dry it.
3) Insert the spark plug back into the spark plug
boot.
4) Place the cap on the top of the spark plug (electrode).
5) Attach the big crocodile clip on the metal part
of the spark plug.
6) Attach the small crocodile clip on the ground
cable eye terminal.
7) Disconnect the 4-pin connector (marked with a
red cable tie) which is connected in the connector
holder.
CHECK OF THE SPARK PLUG AND TIMING SENSOR FUNCTION
8) Insert the key in the switch in the control handle
for approx. 5 seconds (you should hear the
sound of the pump). Remove the key.
9) After 3 seconds reinsert the key in the engine
shut-off switch (the starter switches on). Under
the cap of the mounting tool, you should see a
spark on the spark plug electrode.
10) Switch off the ICU by placing the shut-off key
to the indicator.
11) Remove the mounting tool – disconnect both
crocodile clips, disconnect the connector for the
ICU charging and insert the connector in the
blind plug, remove the cap from the spark plug.
12) Remove the plug from the boot and if it is
not faulty, insert it back in the engine seat.
FIRST SCREW THE SPARK PLUG IN BY HAND in order
not to damage the thread. When the spark plug
is in the seat, tighten it carefully with a spark plug spanner.
If the spark plug is brand new, tighten it with a spanner by 2/3 of a turn.
If the spark plug has been used before, tighten it only by 1/8 – 1/4 of a turn.
13) Place the boot on the spark plug. The boot is
mounted correctly when the spark plug insulator
is covered completely with the boot.
Remark: In daylight, it may be more difficult
to see the spark. It does not have to be one
spark but you can see more tiny sparks.
Warning: The spark test can be repeated
maximum ten times. Overusing the starter
may cause it's overheating and damaging.
