Ignition Timing - Honda CRF110F Service Manual

Disconnect the ignition pulse generator wire connector
(Blue/yellow) (1].
Connect the peak voltage tester or adaptor probes to
the ignition pulse generator wire connector and body
ground.
In the same manner as at the ICM connector, measure
the peak voltage and compare it to the voltage
measured at the leM connector.
If the peak voltage measured at the leM is abnonnal
and the one measured at the ignition pulse
generator is normal, the wire harness has an open
or short circuit, or loose connection.
If bolh peak voltages are abnormal, follow the
._checks described in the troubleshooting chart
(page 4-4).
Refer to procedure for alternator stator replacement
(page 11-5).
