ALTERNATOR EXCITER COIL PEAK
VOLTAGE
• Check cylinder compression and check that the
spa rk pl ug is installed correctly.
Remove the seat assembly (page 2-3).
Disconnect the 4P and 2P connectors f rom the
leM.
Connect t he peak voltage adaptor or peak voltage
tester probes to the connector terminals of the wire
harness side.
TOOLS :
Peak voltage tester
Peak voltage adaptor
MTP07·0286
(U.S.A. only) or

Shift the transmission into neutral.
Crank the engine with kickstarter and read the peak
voltage.
PEAK VOLTAGE: 100 V minimum
IGNITION SYSTEM
If the peak voltage measured at leM connector is
r-~~~~-=:~:~~t~~~~~'l
abnormal, measure the peak voltage at the alterna-
tor exciter coil connector.
Disconnect the alternator exciter coil connector
(Black/red) and connect the peak voltage adaptor or
tester probes to the connector terminal of the
exciter coil side and ground.
In the same manner as at the
[eM
connector, mea-
sure t he peak voltage and compare it to the voltage
measured at the
leM
connector.
• If the peak voltage measu red at the leM is abnor-
mal and the one measured at the alternator
exciter coil is normal, the wire harness has an
open ci rcuit, or loose connection .
• If both peak voltages are abnormal, follow the L _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ---'

REMOVAlIlNSTALLA TION
Disconnect the spa rk plug cap from the plug.
Disconnect the primary wires from the ignition coil.
Remove the bolt and ignition coil.
Installation is in the reverse order of removal.
Tighten the ignition coil mounting bolt to the speci-
fied torque.
