6.4.4 CHECKING THE IGNITION
Remove both side fairings, see 7.1.26 (REMOVING
THE SIDE FAIRINGS).
NOTE
The following procedure refers to a single coil,
though it is applicable to both.
Disconnect the terminals (1-2) from the
a
CAUTION
When reassembling, make sure the electric terminals
(1-2) are connected up properly.
Slip off the spark plug cap (4) (belonging to the coil of
interest) and disconnect it from the cable.
Measure the values of (A) and (B) indicated in the fig-
ure by means of a pocket tester.
It is important to check the continuity of the primary and
secondary windings.
The reading in Ohms does not necessarily have to be ex-
act but if the windings are sound, the resistance values
must correspond approximately to those indicated.
Standard values:
Measurement (A): 2.8 − 5.2 Ω;
Measurement (B): 9.1 − 16.5 kΩ.
a
CAUTION
This measuring method is approximate; if possible,
check the correct operation of the coil by replacing it
with another one in perfect condition.
Repeat the procedure for the other coils.

6.4.5 CHECKING THE PICK-UP

With the engine switched off:
Lift the fuel tank, see 2.8 (LIFTING THE FUEL TANK).
Disconnect the two-way connector (5) (coloured white)
and take the measurements (on the engine-side termi-
nals).
a
CAUTION
When reassembling, make sure the electric connec-
tor (5) is plugged in properly.
Using a pocket tester (scale x 100 Ω), measure the re-
sistance between the terminals of the blue/yellow (B/G)
and white/yellow (Bi/G) cables.
Standard value: 150 − 350 Ω.
If the resistance is infinite (
scribed level, the sensor must be changed.
6.4.6 CHECKING THE CAMSHAFT POSITION
SENSOR
With the engine switched off:
Lift the fuel tank, see 2.8 (LIFTING THE FUEL TANK).
Disconnect the two-way connector (6) (coloured white)
and take the measurements (on the engine-side termi-
nals).
a
CAUTION
When reassembling, make sure the electric connec-
tor (6) is plugged in properly.
Using a pocket tester (scale x 100 Ω), measure the re-
sistance between the terminals of the blue/yellow (B/G)
and white/yellow (Bi/G) cables.
Standard value: 150 − 350 Ω.
If the resistance is infinite (
scribed level, the sensor must be changed.
