CKP SENSOR PEAK VOLTAGE
Remove the seat.
( - 7 - 4 )
Disconnect the ECM coupler.
NOTE:
Make sure that all of the couplers are connected properly and
the battery used is in fully-charged condition.
Measure the CKP sensor peak voltage in the following proce-
dures.
Connect the multi circuit tester with peak volt adaptor as fol-
lows.

Before using the multi circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
Shift the transmission into the neutral, and then turn the igni-
tion switch to the "ON" position.
Pull the clutch lever.
Push the starter button and allow the engine to crank for a few
seconds, and then measure the CKP sensor peak voltage.
Repeat the above procedure a few times and measure the
highest peak voltage.
