IGNITION COIL RESISTANCE
• Remove the front frame cover. (!8-8)
• Disconnect the ignition coil read wires.
Measure the ignition coil resistance in both the primary and sec-
ondary windings. If the resistance is not within the standard
range, replace the ignition coil with a new one.

NOTE:
Be sure that all couplers are connected properly and the battery
used is in fully-charged condition.
• Remove the right side leg shield. (!8-8)
• Disconnect the CKP sensor lead wire coupler

• Turn ignition switch to ON.
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the CKP sensor peak
voltage.
• Repeat the above test procedure a few times and measure
the highest peak voltage.
$ CKP sensor peak voltage: 2.0 V and more (W – G)

If the peak voltage is lower than the standard range, check each
coupler connection or replace the CKP sensor and inspect it
again.
If the peak voltage is within the specification, check the continu-
ity between the CKP sensor coupler and ECM coupler.
#
Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
Normally, use the needle pointed probe to the back-
side of the lead wire coupler to prevent the terminal
bend and terminal alignment.
