Ckp Sensor Inspection - Suzuki Intruder VZ1500 Service Manual

1H-8 Ignition System:
Ignition Coil Resistance
• Disconnect the spark plug caps. Refer to "Spark Plug
Cap and Spark Plug Removal and Installation
(Page 1H-4)".
• Measure the ignition coil resistance in both the
primary and secondary windings. If the resistance is
not within the standard range, replace the ignition coil
with a new one.

CKP Sensor Inspection

Refer to "Electrical Components Location in Section 0A
(Page 0A-7)".
CKP Sensor Peak Voltage
1) Remove the left frame side cover. Refer to "Exterior
Parts Removal and Installation in Section 9D
(Page 9D-5)".
2) Remove the left frame lower cover. Refer to "Exterior
Parts Removal and Installation in Section 9D
(Page 9D-5)".
3) Disconnect the CKP sensor lead wire coupler (1)
and connect the multi-circuit tester with the peak volt
adaptor.
NOTE
Be sure that all of the couplers are connected
properly and the battery is fully-charged.
4) Connect the multi-circuit tester with the peak volt
adaptor as follows:
CAUTION
!
Before using the multi-circuit tester and peak
voltage adaptor, refer to the appropriate
instruction manual.

5) Measure the CKP sensor peak voltage in the
following procedures:
a) Shift the transmission into neutral, turn the
ignition switch ON and grasp the clutch lever.
b) Press the starter button and allow the engine to
crank for a few seconds, and then measure the
CKP sensor peak voltage.
6) Repeat the b) procedure several times and measure
the highest CKP sensor peak voltage.
