6.6.6 CHECKING THE IGNITION COILS

Remove the fuel tank, see 7.1.6 (REMOVING THE
FUEL TANK COMPLETELY).
NOTE
The following steps refer to a single coil, but are
valid for all.
Disconnect the connector (1) from the coil ignition (2).
WARNING
When reassembling,
connector (1) is properly connected.
Pull the cable from the coil (2).
Use a tester to measure (A) and (B) as shown in the
figure.
It is necessary to check the continuity of the primary and
secondary windings.
It is not necessary that the Ohm reading be precise, but if
the windings are intact, the resistance values must
approximately match those indicated.
Standard values:
measurement (A): 0.6 Ω ± 10%
measurement (B): 10 kΩ ± 10%
WARNING
This measurement method is only approximate; if
possible, make sure the coil is in good working order
by using another one you know functions properly.
Repeat the operations for the other coils.
6.6.7 CHECKING THE CRANKSHAFT POSITION
SENSOR
With the engine off:
Remove the left fairing, see 7.1.28 (REMOVING THE
SIDE FAIRINGS).
Disconnect the two-way connector and take the
measurements directly on the sensor.
Use a tester (scale x 1000 Ω)
resistance between the terminals of the sensor,
observing the polarity as shown in the figure.
Standard value: 560 Ω ± 10%
If the resistance is infinite or different from the
prescribed value, the sensor must be replaced.
