Alternator Exciter Coil Peak Voltage - Honda 2000 XR50R Service Manual

If the peak voltage measured at
reM
connector is
abnormal, measure the peak voltage at the pulse
generator connector.
Disconnect the ignition pulse generator connector
(bluelyellow) and connect the peak voltage adaptor
or tester probes to the connector terminal of the
ignition pulse generator side and ground.
In the same manner as at the leM connector, meas-
ure the peak voltage and compare
it
to the voltage
measured at the leM
connector.
• If the peak voltage measured at
the leM is
abnor-
mal and the one measured at the ignition pulse
generator is normal, the wire harness has an
open circuit or loose connection .
• If both peak voltages are abnormal, follow the
checks described in the troubleshooting chart
(page 14-2).

Avoid touching the sp.rk plug .nd tester probes to
prevent electric shock.
NOTE :
Check. cylinder compression and check. that the
spark. plug is installed correctly.
Remove the seat assembly (page 2-2).
Disconnect the 3P and 2P connectors from the ICM.
Connect the peak voltage adaptor or peak voltage
tester probes to the connector terminals of the wire
harness side.
