Alternator - Honda CB250N Shop Manual

Unit
Inspection
Provided the
circuit
on the wire harness
side
is
normal and there
are no loose
connections
at
the connector, inspect the
regulator/rectifier
unit
by measuring
the resistance
between
the terminals.
NOTE
•
You'll get false readings
if
the probes touch your
fingers.
Use
the specified multimeters. Using other
equipment
may
not allow you to obtain the correct
results.
This
is
due
to
the
characteristic of
semiconductors,
which have
different values
depending on the applied voltage.

•
An
old
battery stored
in
the multimeter could cause
in-
accurate
readings.
Check
the battery
if
the
test results
are
not
as
expected.
•
When
using the
KOWA
multimeter,
remember
vaiue that
all
readings should be
multiplied
by
1
00.
Replace the
regulator/rectifier unit
if
the resistance value
between
the terminals
is
abnormal.

Removal
Remove
the
fuel
tank (page 2-4].
Disconnect
the regulator/rectifier connector..
Remove
the
mounting
bolts
and
regulator/rectifier unit.
Installation
is in

REGULATOR/
RECTIFIER
Disconnect the
alternator
3P
connector.
Measure the resistance between
the
two
Yellow wire
ter-
minals.
Standard:
Yellow-Yellow:
0.2-0.6
SJ
(20°C/68°F)
Replace the
stator
if
the resistance
is
out
of
specification
or
if
there
is
continuity
between
the Yellow.
