VOLTAGE REGULATOR INSPECTION
Remove the front cover. (screws x 3 x 2).
Remove the front cover mounting
screw(screws x 1)and remove the headlight
wiring connector.
Disconnect the 4P connector on the diode,
and check the continuity between main wire
terminals according to following method.
Main wire circuit inspection
Item (wire color) Judgment
Check voltage between
battery terminal (red) and
ground (green).
Battery voltage
Check continuity between
ground(green) and frame.
Continuity
Check illumination wire
(yellow) to ground.
(disconnect the connector of
the resistor’s pin and
automatic by-starter pin.
Illumination switch is in OFF)
Continuity &
resistance
Check charging coil (white) to
ground) Continuity &
resistance
If the measured value is abnormal, check the
abnormal wire circuit. If components are
good, it could be a poor wire circuit.
If all items are in good condition, then
replace the voltage regulator.
If main wire circuit check is in normal and
there is no loose in the pins of voltage
regulator connector, then measure the
resistance between the connector of voltage
regulator.

If the resistance values are abnormal among
the pins, replace the voltage regulator.
Caution
z Do not touch the probe of multi-meter by
fingers, then the resistance values will be
incorrect because there is some resistance
existence in human body.
z To use the multi-meter recommended by
E-TON. Otherwise, the measured
resistance might be different.
