Ignition Switch Circuit Inspection - Honda Metropolitan CHF50 Service Manual

BATTERY/CHARGING SYSTEM
Check the following at the harness side connector
terminals.
BATTERY LINE
Short the Green/White wire terminal on the body
ground with a suitable jumper wire.
Measure the voltage between the Red wire terminal
and ground.
When the ignition switch is turned to OFF, there is
no voltage and when the ignition switch is turned to
ON, there should be voltage.
If the measurements are abnormal, inspect the main
relay (page 15-11).
GROUND LINE
Check the continuity between the Green wire termi-
nal and ground.
There should be continuity at all time.
If there is no continuity, check for an open or short
circuit in the wire harness.
CHARGING COIL LINE
Measure the resistance between the Red/yellow,
Red/White and Red/blue wire terminals.
STANDARD: 0.05 - 0.5 Q (20 °C/68 F)
IGNITION SWITCH CIRCUIT
INSPECTION
Remove the front cover (page 2-4).
Disconnect the ignition switch 3P (Black) connector.
Measure the voltage between the Red/blue wire ter-
minal and ground.
There should be battery voltage at all time.
If there is no voltage, check the following:
- Open or short circuit in wire harness.
- ECM battery line (page 15-9).
Disconnect the ECM 26P connector.
Check the continuity of the Red/green wire termi-
nals between the ignition switch 3P connector and
ECM 26P connector.
There should be continuity.
