Exciter Coil Peak Voltage
NOTE
Install the spark plug into the cylinder head and meas-
ure the peak voltage under normal cylinder compression.
Remove the rear fairíng (page 2-3).
Remove the CDI unit disconnect 2P connector from the CDI
unit.
Connect the peak voltage adaptor EB probe to the exciter coil
(black/red) wireterminal of 2P connector, and the e probe
to the body ground.
Crank the engine with starter motor and read the exciter coil
peak itoltage.
Connection:
Black/red wire terminal EB-body ground e
Peak voltage: 100 V minimum
Toavoid possib/e electrica] shock during voltage mesure-
rnents, do not touch test probe metal parts.
If the peak voltage measured at the CDI unit connector is ab-
normal, disconnect the alternator wireconnector (black/redl
and connect the adaptor probes to the exciter coil terminal and
body ground.
In the same manner as at the CDI unit connector, measure the
peak voltage and compare it to the voltage measured at the
CDI unit connector.
If the peak voltage measured at the CDI unit is abnormal
and the ene measured at the exciter coil is normal; the wire
harness has an open circuir or loose connectíons.
If both peak voltages measured are abnormal, check each
ítem in the troubleshooting chart. If all items are normal,
the exciter coil is faulty.
Pulse Generator Peak Voltage
NOTE
Install the spark plugs into the cyiinder head and meas-
ure the peak voltage under normal cylinder compression.
Remove the rear fairing (page 2-3).
Remove the CDI unit from the rear fender and disconnect 4P
connector from the CDI unit.
Connect the peak voltage adaptor EB probe to thepulse gener-
ator (blue/yellow) wire terminal and the e probeto the bodv
ground.
Crank the engine wíth starter rnotorandreacthe pulse gener-
ator peak voltage.
Connection:
Blue/yellow wire terminal EB-Body grounde
Peak voltage: 0.7 V mínimum
