HEADLIGHT VOLTAGE INSPECTION
RegulatorlRectifier With Built-in AC Regulator:
For a regulatorlrectifier with a built-in AC regulator, measure
the headlight lighting voltage.
CAUTION
.
Failure to measure the headlight voltage may lead to
electrical damage of lighting components.
If the model is not equipped with a tachometer, connect an
engine tachometer.
Remove the headlight and start the engine
Turn the headlight on Hi-beam.
With the headlight wires still connected, measure the
headlight lighting voltage between the terminals connected to
blue
(+)
and green
(-)
wires.
Gradually increase the engine speed and read the voltage at
the rpm specified in the Model Specific manual.
Refer t o the Model Specific manual for service data.
Select the AC range on your multimeter. (AC current flows t o
the headlight)
Use the specified multimeter. The measured headlight-
regulated voltage may vary depending on the multimeter used
because of the characteristics of the output waveform.
