Alternator Charging Coil; Charging Voltage Inspection - Honda Metropolitan CHF50 Service Manual

BATTERY/CHARGING SYSTEM
CHARGING VOLTAGE INSPECTION
NOTE:
• Make sure the battery is in good condition before
performing this test.
Do not disconnect
the battery or any
cable in the
charging system
without first
switching off the
ignition switch.
Failure to follow this
precaution can
damage the tester
or electrical
components.
Start the engine and warm it up to the operating
temperature; then stop the engine.
Connect the multimeter between the positive and
negative terminals of the battery.
NOTE:
• To prevent a short, make absolutely certain
which are the positive and negative terminals or
cable.
With the headlight on high beam, restart the engine.
Measure the voltage on the multimeter when the
engine runs at 5,000 rpm.
Standard:
Measured BV < Measured CV < 15.5 V
- BV: Battery Voltage (page 15-7)
- CV: Charging Voltage (page 15-8)
ALTERNATOR CHARGING COIL
INSPECTION
Remove the luggage box (page 2-6).
Disconnect the alternator/starter 3P (Black) connec-
tor.
3P (BLACK) CONNECTOR
Measure the resistance between each wire termi-
nals of the alternator side connector.
STANDARD: 0.05 - 0.5 Q (20°C/68°F)
Check for continuity between each wire terminals of
the alternator stator side connector and ground.
There should be no continuity.
Replace the alternator stator if resistance is out of
specification, or if any wire has continuity to
ground.
Refer to page 11-4 for alternator stator replacement.
