Ignition Coil; Ignition System - Honda Metropolitan CHF50 Service Manual

If the peak voltage measured at the ECM connector
is abnormal, measure the peak voltage at the pulse
generator connector.
Disconnect the alternator/starter 6P (W) connector
and connect the peak voltage tester or adaptor
probes to the connector terminals of the alternator/
starter side.
In the same manner as at the ECM connector, mea-
sure the peak voltage and compare it to the voltage
measured at the ECM connector.
• If the peak voltage measured at the ECM is
abnormal and the one measured at the alterna-
tor/starter is normal, the wire harness has an
open or short circuit, or loose connection.
• If the peak voltage is lower than standard value,
follow the checks described in the troubleshoot-
ing chart (page 16-4).
Install the removed parts in the reverse order of
removal.
